Web338 has shown poor performance and stopped responding, so we have taken the server offline for a filesystem check and hardware inspection. We will update this post as progress completes.
2013-04-28 05:09 UTC: The fsck has finished and the server is back online, but there are still some issues which need to be addressed, so the server will be rebooted again once more soon.
2013-04-28 05:44 UTC: We are now rebooting the machine after some changes to bring it fully back online.
2013-04-28 06:49 UTC: The server is now online and functioning normally.
