On the evening of Monday, November 12, we experienced a few of hours of downtime due to an explosion at Rackspace’s main data center in Dallas, TX. This event lead to the eventual failure of a backup cooling system. Without adequate cooling, our servers had to be shut down to prevent permanent damage. We have detailed the events that led to the downtime. We deeply apologize for any inconveniences this may have caused and will work hard to make sure we reduce the likelihood of this happening again.
