We thought we had some small corruption on one disk partition, but it turns out the problem is more serious and will require hardware replacement. New hardware is being provisioned now, and we will be moving onto the new server as soon as it is available.
It may not be possible to make backups between now and when the migration is done (we do have full backups from this morning, however). So contributors, you may want to wait to contribute articles until the problem is resolved.
We apologize for any inconvenience.
