Update 27/03/08: We are doing emergency data moves to quell the stem of problems recently caused by your file server. During these moves, your data may be inaccessible. We are moving as we can off as fast as possible. Very sorry about the continued inconvenience!
Update 27/03/08 This series of moves has finished. We are going to keep an eye on things to see how much it helped and may have to do more moves tonight and tomorrow morning to get everything working smoothly again. This post will be updated with more information as soon as possible.
Things are still running slow, so there are still problems with the site.
