I don’t see anything in the logs to indicate an extended outage, but the third party performance monitoring script that tracks the forum application has been causing the forum to crash several times per day 😕 I need to find a replacement, obviously.
The forum restarts itself within a second or two, and if you try to access the site during that brief period, it should just throw an error. The fact that you couldn’t access the site at all for a half hour is weird.
