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...

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...

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...
