Web178 has been taken offline for emergency maintenance on mysql.
2013-06-28 23:41 UTC: We are taking the server offline to perform a file system check in order to verify the MySQL problems are not being caused by file system corruption. We will update this post as the maintenance continues.
2013-06-29 01:23 UTC: The file system check has finished and the MySQL data corruption was not fixed as part of the check. We are continuing to investigate recovery options.
2013-06-29 02:31 UTC: We are now attempting a full export of any databases that do not have corrupted data. During this process the Nginx web server may be offline to stop automated queries from firing and possibly accessing corrupted tables causing the MySQL server to crash.
2013-06-29 03:31 UTC: The MySQL server is now back online and fully functional.
