Outage yesterday

We were upgrading the servers that the pool web site is running on yesterday and had an outage for a few hours. It should all be back to normal now.

The upgrade was (mostly) about getting all our servers up from RHEL 3 to version 5 (before we had mostly RHEL3 boxes and a few with 4 and 5 ...). Now when they are all the same it's easier for us to manage the configuration across all the boxes and soon we'll have some more high availability things setup for the pool system. Long term the goal is to get more of the infrastructure completely distributed, but the website (for showing stats etc) will likely still be in just one place.
