I did some database maintenance today -- moving our workers around! -- and this caused a glitch in the replication between our old databases and the new ones, so the new ones weren't getting all the updated data.
What this means to you: if you saw problems trying to update your access list or subscription filters, or with community invitations, or viewing support requests, that was caused by the glitch in replication. I'm really sorry for the inconvenience.
This particular issue won't recur, since it was caused by a very specific circumstance related to moving the workers around. Since I'm done moving them, the problem won't happen again.
