If you are reading this the forum is back up.
I am sorry for the extended downtime. Given Gophercon, travel and the like most of the people who look after the forum, on a volunteer basis, were not able to respond quickly.
Restoring service was also slowed by a possible bug in a recent patch to discourse and a server instance that got itself into a strange state.
After a reboot of the server instance, some database commands, and a rebuild of the discourse instance we seem to be operating again.
Thanks for your patience.
