Faebot has been getting the response below to SQL connections:
ERROR 2003 (HY000): Can't connect to MySQL server on 'commonswiki.labsdb' (111)
I have run a few long queries today, trying to get my user list report back up (Userlist) after the database had one of the critical tables removed last year. I have no idea if this is related, though I can see that Quarry is working.
