I recieved two notices on Wikia (like the ones you get when you have new messages).
One was a notice about Editing being disabled at 10am
Another one was "testing".
I know that Wikia have been having server problems recently and that they're planning to upgrade the MediaWiki software to the version that Wikipedia is using. (Wikipedia are a version ahead of Wikia.)
What does this hopefully mean? Personally, I hope that whatever they're doing today will improve the reliability of the Wikia server and to stop bugs such as a wiki not loading in Firefox and reaching the "backup datacenter".
