LT asked the same thing via PM several days ago.
Does the site break for you between 4-4:30AM ET / 3-3:30AM CST daily?
Told him that it's
probably the BYOAC servers doing backups every day at that time since nobody's using the site then.

Forums and wiki are both unavailable at that time.
There's often a few minutes downtime around Midnight CST, too -- maybe Saint's or my ISP host servers rebooting.
