We’re moving the site to a new server this Thursday, 13 June. The site will be unavailable for a period between 1–6 pm, US Central time.
The actual downtime should be less than that. The first step will be locking the discussion forums, so they will be read-only for a period. Then we’ll move all the databases. And once they’re up and running on the new server, I will unlock the discussion forums so you can post again.
