Apollo server migration to upgrade CentOS

During the week of March 5th we will be migrating all accounts currently on the Apollo server to a newly provisioned server in order to safely perform a major version upgrade of CentOS, the server operating system. Apollo will be upgraded to CentOS 6.2, and we will also use this opportunity to upgrade the server hardware to a 64-bit machine, which has better memory handling.

CentOS is the Enterprise version of Red Hat Linux. The advantage to an Enterprise version is a longer life/upgrade cycle of five years (compared to other Linux distros that can be as short as 18 months). Why this matters is because though minor OS updates can be done in place, major version updates can not (or more accurately, it's strongly recommended against doing so).

The only noticeable change will be that because we'll need to migrate to a new machine, the server IPs will change. Therefore any IP-based usage you'll need to edit the IPs you're using. After all accounts are migrated over to the new server we'll update the nameserver IP, so the DNS transition should be smooth and uneventful.

All accounts (website files, email) will stay on the original server until they have been fully copied to the new server, tested for accuracy, and the DNS has finished propagating. Because of this we anticipate no downtime associated with this upgrade and account migration.

Apollo server briefly offline

Today from 2:10pm to 2:38pm PST (5:10pm-5:38pm EST) the Apollo server was unresponsive and offline. There was nothing wrong with the server itself, the outage stemmed from a temporary network issue in the section of the data center were Apollo is located. The data centers' Engineers resolved the issue and it should not reoccur.

We apologize for this disruption in service, maintaining uptime is a high priority to us. As soon as we are aware of any outage (even small hiccups) status reports are posted to our Twitter account and here on this blog.

3:40pm PST UPDATE: Apollo server is again unresponsive. Our trouble ticket with the data center has been reopened. Updates as we have them.
4:13pm PST UPDATE: Apollo is back up. Again we apologize for this.
