ExchangeDefender Redundancy: Technical Implementation Details
In August our core data center in Dallas Texas suffered its worst outage in the past 8 years after an ATS power failure. Since the power outage was due to the ATS, backup power was not able to be routed to the redundant feeds to all our servers and as a result critical services were knocked offline. ExchangeDefender’s core focus is on-time clean mail delivery, and inbound mail delivery speed was impacted but was still available and processing mail for all customers. One of the most beneficial features of ExchangeDefender is LiveArchive which acts as a continuity solution for ExchangeDefender clients by keeping an additional copy of all client inbound and outbound mail. During the outage, LiveArchive was knocked completely offline for the first time since release. The full scale outage of LiveArchive prevented clients on Hosted Exchange and ExchangeDefender from being able to reach their continuity solution, creating lots of issues for partners and their clients. The outage caused us to reevaluate the redundancy in our solutions across the board starting with additional ExchangeDefender nodes and implementation of LiveArchive in our Los Angeles Data Center.
Today, I would like to update you on what we’ve done and announce the immediate availability of the new solution that will work even if one of our data centers is offline completely for an extended period of time.
Complexity & Size Problems
The biggest complexity of the additional LiveArchive network was accepting mail between multiple datacenters and routing it to the nearest network, and finally synchronizing the mail between with remote networks. Due to amount of mail processed by ExchangeDefender on a daily basis, we were prevented from using the built in redundancy in Exchange 2010 like Database Availability Groups and Microsoft software load balancers for OWA and SMTP.
On average our Dallas LiveArchive network processes and stores over 115 million messages a day. By adding redundant LiveArchive networks we will automatically double our message processing count on our Exchange transport servers due to synchronization between networks. The additional overhead would also create immense load on our network if we utilized Database Availability Groups as our Dallas network is already storing over 382 TB of data. The notion of having a desynchronized network or increasing LiveArchive mail delivery time was not a viable solution as LiveArchive would then fail as a continuity solution.
The Solution
To overcome the obstacles and limitations we faced, we started to develop custom solutions to tie in with our LiveArchive networks and redesigned our network layout and made minor changes to the LiveArchive storage length in Los Angeles to one month.
The first issue to tackle was the Active Directory layout as we could not tie Active Directory into our already established and quite frankly rock solid Dallas Active Directory network. In the event of another catastrophic failure in Dallas the inability to contact the primary Active Directory network would render the Los Angeles copy useless unless we create them as unique sites. Although this was possible, we felt with the power of our automation between ExchangeDefender and LiveArchive was better suited for the job as the above solution would cause too many changes to occur during a failure, including many DNS changes. We decided to have unique Active Directory domains between sites and we hooked user account creations for Los Angeles into our ExchangeDefender provisioning.
The second issue was mail delivery design between sites. The original design of LiveArchive mail routing would cause the LiveArchive copy of inbound mail to always be routed to Dallas for delivery to LiveArchive. The Achilles heel of the design was always in mail that was delivered to Data Centers outside of Dallas as it would cause the original mail delivery to be delayed a few seconds as a copy was dispatched to Dallas. Up until a few months ago our original design was acceptable and was only cause minor delays about twice a year. As the amount of mail processed increased, the delays became more noticeable. Mail delivered to networks outside of Dallas began to see increased processing time and eventually took twice as long compared to mail that was accepted by Dallas. By adding an additional LiveArchive network in Los Angeles we were able to route mail that arrived in Los Angeles to our Los Angeles LiveArchive network.
The final issue was mail synchronization between sites. We took advantage of the powerful extensions into Exchange by creating a custom Transport Agent that would copy submitted messages from each ‘local’ LiveArchive message to the remote network for processing. By utilizing custom routing and Edge servers we were able to successfully copy mail and provide real time processing and delivery between both LiveArchive networks.
In the event of a failure in either site, ExchangeDefender mail will automatically fail over to an additional DC and all LiveArchive mail will route to the network with available heartbeats. Upon creating an outage notification, our team will modify the DNS records for https://livearchive.exchangedefender.com to route to Los Angeles.

How to position and sell Exchange messaging
Have you considered adding hosted Exchange or other cloud messaging solutions to your portfolio? If not, you’re already behind Microsoft, Google, IBM and many others. Even if you have considered it, the marketplace is getting flooded with cloud marketing and you need to be savvy to get your solution front and center and not get displaced by he competition. Here is how!
Hosted Exchange 2010 + SharePoint 2010 and Exchange 2010 Essentials: while they’re only two simple, reliable solutions, they pack a powerful punch that solves a wide variety of small business messaging and collaboration challenges. When we surveyed our partners, 90% of them told us that Hosted Exchange is their single best “foot in the door” or relationship builder product. This is because small businesses are becoming more and more dependent on their messaging technology, while the cost of deploying and managing it continues to skyrocket. They need affordable, reliable messaging technology to support their unique businesses – and Hosted Exchange + SharePoint and Exchange 2010 Essentials from ExchangeDefender offers small businesses of all kinds an attractive combination of rich features, affordability, security and flexibility.
Differentiation
Our small business clients certainly have options when it comes to cloud-based messaging solutions – Microsoft Office 365 and Google Apps for Business are two major alternatives with which many small business clients may be familiar. Hosted Exchange 2010 + SharePoint 2010 and Exchange 2010 Essentials from ExchangeDefender are fundamentally different, offering users the familiar Microsoft Outlook user experience at an unbeatable value with the flexibility to deploy just the right tools that the business needs.
Some SMB clients don’t want or need a full-featured messaging and collaboration solution and want to minimize their costs of maintaining basic functionality. While Google Apps for Business offers an attractive price point with “pared down” messaging features, its unfamiliar interface may turn off folks who are comfortable with the Microsoft user experience. Exchange 2010 Essentials delivers the best of both worlds – minimal complexity using Outlook Web Access protected by ExchangeDefender Essentials along with the ever-popular Public Folders and Distribution Groups at a competitive price point, just $6 per month per mailbox. Clients can even integrate with their existing copies of Outlook to get that fat client experience they know and love.
Feature/Benefit Discussion
Some SMB clients will require more advanced features like message encryption or archiving for regulatory compliance, and may find the messaging features included in Microsoft Office 365 and Google Apps for Business lacking – security, encryption, and archiving aren’t included in Google Apps for Business, and while Microsoft Forefront protects Office 365 email users, archiving, encryption, and e-discovery aren’t included. Hosted Exchange 2010 + SharePoint 2010 delivers the full Microsoft Outlook experience with SharePoint’s powerful online portal and groupware functionality, including ExchangeDefender protection and our Live Archive service. Integrate with Blackberry Enterprise Server, split domains, brand the portal experience and leverage the “tried and true” Public Folders feature if desired, as well, all for only $10 per month per mailbox.
Whatever your clients’ needs are, you can get your foot in the door and start building a strong relationship (or deepen an existing one) with the powerful combination of Hosted Exchange 2010 + SharePoint 2010 and Exchange 2010 Essentials from ExchangeDefender. Now you can offer your clients an attractive combination of rich features, affordability, security and flexibility on our globally-redundant infrastructure that even most large enterprises cannot build in-house.
Do you find this information useful?

Introducing Geographic Redundancy to ExchangeDefender Services
As you may be aware, we had our first network-wide outage in our primary data center (Dallas) back in August and our redundancy plan did not deliver on the promise that we should expect. Our CEO went over the details of the outage and during his webinar, we made a promise to revamp our network and infrastructure to prevent the impact this had on our partners moving forward. Once all services were restored, we began playing the outage backwards to figure exactly what went wrong and how we can eliminate the possibility of it ever happening again.
The items that floated to the top were LiveArchive’s failure and an unforeseen level of reliance on Dallas by our Los Angeles ExchangeDefender network. Our Exchange Architect and lead engineer, Travis Sheldon, outlines the changes made to our LiveArchive structure to ensure that if Dallas goes lights out, LiveArchive can keep on to ticking without missing a beat.
That leaves changes to our mail processing. Once the outage happened, our ExchangeDefender NOC team was overseeing the mail flow going to Los Angeles, however, the failure point was the processing speed. The processing speed delay basically blew out all of our disaster recovery metrics that showed us that LA could handle the load on its own. The team’s task quickly became finding the delay within the process. In this case, our transparency became our worst enemy. The fact that we log everything to make it accessible to our partners for their clients was causing the delay. Our Los Angeles nodes were attempting to write data back to an unresponsive database. Think about that for a second, every step of the way for every email we process, was now attempting to update data to an unresponsive network. Needless to say this delay in processing caused all of our queues to grow explosively, thus causing massive delays in delivery.
The other major part of the outage was our outbound network. At the time, our multihomed smart host cluster was at the time housed primarily in Dallas, with standby nodes in Los Angeles. Here’s the problem, since these nodes weren’t in production they did not have active access tables, which basically rendered them useless. So now we had our trail of blood and tears of how and why we failed, but we also had a blue print on how to ensure history didn’t repeat itself. Here is what LiveArchive side of LA looks like now:
So in addition to the new LiveArchive Exchange 2010 cluster in Los Angeles, here’s what we did:
1. We increased the hardware and bandwidth capacity by 80% in Los Angeles. This brought it on par with our Dallas network, which has in the past and with ease handled the load during peak on its own without delays. In addition, we also increased our capacity in Dallas an additional 20%, this is accommodate future growth without having to experience any processing delays.
2. We deployed master to master replication of all of our core processing databases. So now our ExchangeDefender Los Angeles nodes do not rely on any Dallas resources for mail processing. This means two big gaps were closed, if there were a Dallas outage, processing speed would not suffer and that our logging would not need to be sacrificed in the name of processing speed.
3. We doubled our outbound capacity in Los Angeles and they’re live servers instead of standby. This way if an outage occurs, all routing/access/archiving/encrypting rules are already up to date and ready to go. As an added benefit this expansion increased our outbound processing speed and capacity by 80%.
The lessons we learned from this event will only allow us to provide you with better and faster service, so you can in turn deliver the same to your clients. We’ve already successfully stress tested our new infrastructure on multiple occasions with great success and we’re confident about the future of our solutions.
I have worked with many of our partners through the years and, if you don’t mind, I wanted to share some resources that I find most of our partners are not aware of. As the person that oversees all of our support services I can tell you that frustration is a part of the game and we can extend a much better service when you’re plugged into everything that the support side of ExchangeDefender as an organization offers. Here are some tips:
1. Make sure all of your employees are reading our NOC site. http://www.exchangedefender.com/noc While the NOC alerts sync up with Twitter, Facebook and our support portals, our NOC site provides a lot of useful information about how to explain the problems that happen. Our clients are aware things will go down from time to time so keeping them in the loop is critical.
2. Make sure all your employees are in the support portal and that the information is correct. Have you ever had the frustrating experience of opening a ticket only to be asked for more information? We find that most tickets that aren’t addressed by us immediately (and our average response time is a topic for a different blog) can drag on and a quick call can often resolve it. We’re in support, we won’t call you to sell you stuff. But if we have a number to call we can figure things out very rapidly.
3. Rely on the portal. https://support.ownwebnow.com is where we live. All of our communications, alerts, NOC, service monitoring and staff have this open whenever they are at their desk. Monitors around the office show how many issues are being worked on, what everyone is up to, which changes are being made. While we love to talk to our partners we have to take your security into account so make sure that everything goes through there. Yes, we do escalate stuff to Vlad from time to time.
4. Most importantly: Save the info below.
I have been with Own Web Now for years and I often like to tell people that I’ve known Vlad Mazek before he knew how to speak English. If there is anything on the support side that I can help with please feel free to contact me. So much for the introductions, look forward to with you all.

July Update
We have so much new stuff ready to go this month that I just couldn’t wait for the newsletter to be published. I’m taking a moment away from all the craziness to update you on what we’ve been up to this month. For full details you will have to look at the newsletter and join us for the webcast:
New ExchangeDefender
https://www1.gotomeeting.com/register/275688153
August 4th, 2010 at noon EST
You really want to clear your schedule and attend this webcast, some of the stuff discussed during the show will not be in the recorded webinar, nor will be the offers that we’ll extend to our partners that are on top of it all. Plus you’ll get exclusive peak of all the new stuff joining the Shockey Monkey family!
New Office
Last weekend we moved into a beautiful new office on the 12th story of The Plaza in the heart of Downtown Orlando. We’ll soon have live webinars, webcams and other stuff to let you interact with the staff and keep an eye on us. If you’re ever in Orlando we’d love to have you stop by at 121 S Orange Ave.
New ComplianceArchive
We’ve spent a lot of time working on the new ComplianceArchive product. This effort was far too big to bundle in with the ExchangeDefender 7 launch and we’ve learned a lot about how different parts of our client base rely on archiving. On the high end, we have financial and regulated industries that need high end compliance for legal reasons. In SMB though, we have the packrat mentality, and archiving is done more for locating items quickly. Obviously there is a price difference between different solutions as they are built to a different spec for a different purpose.
New International Numbers
ExchangeDefender 7 launch caught us by surprise – huge surprise. We haven’t been this busy in years and we’ve never seen a faster adoption of our product than in the past few months. As a result we have had to shuffle personnel around for training purposes and addressing the peak hours. Temporarily, we’ve been forced to reduce our phone support hours for Tier 2 from 24/7 to 4AM – 8PM EST and our support portal hours from 24/7 to 4AM – 1AM.
We have also had to evaluate a lot of negative feedback we’ve received about our phones. This was addressed in the move and I hope many of you can appreciate the difficulty in establishing a VoIP presence in multiple countries. So here are the new numbers we are currently testing:
Australia: 02 9037-4202
UK: 08435570373
New Hosted Exchange Pricing
The launch of Microsoft’s new Office 365 has caught many of our partners by surprise. Not to worry, we have a very competitive new pricing scheme that will be announced during the webinar. Keep in mind that we do not encourage pricing competition but you need to make alternatives – so consider www.CloudBlock.com as one.
Oh, the new Compliance Archiving…
We’ve pretty much rewritten everything.
· Written on top of .NET 4.0 Framework
· Supports Exchange 2007 SP1 & Exchange 2010
· Can be installed on any windows machine (XP, Windows 7, SBS, etc). (Does not have to be installed on the exchange server)
· Extreme validation and real time response validation.
· Service does NOT REQUIRE administrative login credentials, runs as local system.
· Allows management of an unlimited number of Hosted Exchange Servers for Compliance.
· Multithreaded service model, supports up to 10 running threads at one time.
· Start/Stop Service is handled gracefully to allow any pending threads to complete the step they are on then terminate.
· Archived mail is check for integrity, if an insert fails due to (bad connection, error in record, etc).. it will roll back any previous actions for that message.
· Attachments are now stored as individual records, this will allow attachment searching and direct download of attachments.
· Removed the DISK IO dependency from the program, messages are no longer written to disk. Everything is done in memory.
Looking forward to seeing you all in August and on behalf of the entire ExchangeDefender team, wishing you continued prosperity, our partners grew 21% in Q2!
Sincerely,
Vlad Mazek

ExchangeDefender 7 Bugfix Update
It’s been nearly four days since the launch of ExchangeDefender 7 and we wanted to offer you an update on how things were going. In a word: astonishing! This is the best launch we’ve ever had by a country mile and for the first time ever we’re not receiving complaints about the UI, mostly thanks to the marketing and client facing documentation being delivered well in advance. We’ve been receiving glowing compliments on the new UI and we’ve worked extremely hard on the QA process.
Gabriel Gonzales has been in charge of the QA followup process for ExchangeDefender so if you’ve found an issue with it, you’ve spoken to Gabriel or Frankie. We wanted to make sure that all management levels were available to you with a clear development schedule so we can fix problems right away. The average turnaround time on bugs to fixes has been under an hour.
Good news: Great feedback, lots of excitement about the new product and happy clients.
Bad news: It’s not perfect. Lot’s of performance enhancements in the works, new marketing in the plans and the ExchangeDefender Gold program coming soon.. but in the meantime, here is the list of fixed bugs just in case you’re asked about them by your clients – the bugs have been fixed.

ExchangeDefender MSP Alerts
Thanks to so many of you that participated in our ExchangeDefender 7 preview last week. The beta is a week or two away and we are still putting some finishing touches on the features that will ship down the road after the initial core launch of Security, Continuity and Compliance. Today we have an open ended question regarding one of the features and we hope you take a moment to let us know what you think.
If there was a single value proposition we are making in ExchangeDefender 7 it’s the managed aspect. You are no longer subscribing to a tool, you are getting a service that protects the most important tool businesses have on the Internet. Without email, the company may as well take a day off.
We are building in a MSP interface to ExchangeDefender that will monitor all servers protected by us. Every 15 minutes we will poll your email server from all of our data centers and if nothing can connect to it, we will issue an alert.
Question: When should we notify you?
We are aiming to create a configurable alert system on top of the service so it can notify you if 4 consecutive tests have failed (in this scenario, we couldn’t reach your server for an hour) or we can issue an alert every time we cannot connect to your mail server. We don’t know what’s right – if too many alerts are sent, will the alerts be ignored. Likewise, if too few alerts are sent will you be finding out about an issue from your client?
We initially intend to make alerts available via email and SMS and through professional RMM services tools LPI and Kaseya and PSA from Autotask and Shockey Monkey.
If you have a suggestion please login to https://support.ownwebnow.com and click on Resources > Features and create a new Feature request. ExchangeDefender 7 is 100% based on the feedback from the new feature request category filled out by our partners, keep on using it if you want the product to fit you better!
