Emergency Maintenance

On January 8th we were informed by Rackspace that one of our cloud server physical hosts is alerting for bad RAM. Our servers use ECC (Error Correcting Code) RAM and can handle a few errors, but when they start to happen, its time to replace the RAM before the server crashes. In an effort to prevent unplanned downtime, we have scheduled an Emergency Maintenance with Rackspace to replace the RAM in this server. We are currently scheduled for sometime between 12 AM and 3 AM Pacific (3 AM - 6...

Morgan has asked me to do some testing on our servers performance to show to our clients. This blog post will contain the results.

The Castle Back in November 2012 Morgan and I went and visited Rackspace in San Antonio. They have a pretty cool office; they've converted an old mall into their headquarters. The Castle. We talked about our hosting and how we can continue to grow. They talked to us about a Private Cloud based on OpenStack. But let's back up a second and talk about how our current infrastructure works. We currently have 3 different kinds of servers. Data Feed Processing / Image servers, Data Feed Databas...

Morgan, R&D and I have been working hard to improve how our code handles sending email - this is to increase the number of emails which make it to the inbox and to reduce the likelihood of being blocked by a major Email Service Provider such as Yahoo or AOL. Bounces and Feedback Loops I have signed up for the Feedback Loops of AOL, Yahoo, and Hotmail. Now, whenever one of their users reports an email as SPAM, a copy is sent to us. I have code which will, at that point, read our postm...

Currently our servers are connected to each other and the internet with a 100 megabit network. We are beginning to reach the capacity of this network. In order to prevent congestion between our servers and the internet we are pre-emptivly upgrading to a gigabit network. We will be replacing our firewall, load balancer, and switches. Rackspace will also provide us with a gigabit connection to the internet. During this time we will loose all connectivity to the internet and your sites will b...
