The disc has been replaced, and the array is starting to rebuild. - Cyan Sat 6 Aug 20:58 BST
Our storage server is at risk of outage due to a scheduled replacement of a failing disk. The disk will be replaced by the data center personnel. Depending on how the disk is replaced, there could be a brief outage. This outage, if it occurs, would impact uploads to the site as well as attachment downloads. Most file and image downloads will most likely be cached, and so the majority will not experience any issues. - Cyan Fri 5 Aug 00:10 BST
