First I want to apologize for the outage! The server software upgrade was not supposed to have a noticeable impact on the users or sites. I upgraded a piece of software on the server that handles running scripts (programs) on the server and found that one of the other sites I host was not compatible with the upgrade. Due to the load put on the server it was difficult to repair and took a bit of time.
This had nothing to do with anything on RF.com.
If anyone has any questions feel free to ask!
