One of our IMAP servers just went offline. I’m investigating the cause, but meanwhile all users are being transferred over to the replica and should be online again in about 2 minutes.
Update (by robm at Fri Feb 5 03:50 UTC)
All services are restored.
Unfortunately when the IMAP server went down, an internal "ping" failure caused a restart attempt on one of our frontend servers which didn’t complete. This meant that for some users, logging into IMAP, POP and SMTP services was failing for a while. This has also been fixed.
