The filesystem on Web245 went read-only. We are booting the server into rescue mode to run a filesystem check. We will update this post as maintenance progresses.
2013-11-20 16:45 UTC: The filesystem check is 25% through its second pass.
2013-11-20 17:39 UTC: The filesystem check is complete and Web245 is back online. Some filesystem problems were detected and repaired. If you notice any problems with your sites or data, then please open a support ticket for assistance.
