Incident Report: WebDAV/CalDAV/CardDAV services unavailable..

On Monday morning at 03:22 CET the kolab Now $DAV services stopped working.

While resolving a performance issue for $DAV connections, we moved around¬† servers from an old infrastructure to a new infrastructure, and with that the rotation of logs. Unfortunately a tiny bit were missed while configuring the new servers, which caused the log rotation attempting to reload httpd (while that wasn’t needed). In turn, reloading httpd didn’t succeed and timed out, and the new DAV servers were left in a maintenance state;¬† unavailable.

This happened at ~ 03:22 CET. As these are new DAV servers, they were only included in the standard monitoring, and no one got notified about the problem until it was discovered at 07:47 CET. The configuration was promptly corrected and the new DAV servers came back online right away (and was added to the monitoring notifications). At this time everything should be available and working as expected.

We apologize for any inconvenience that this may have caused.
