The BBS, Wiki and AUR will be moving to a new server starting today at 13:30 UTC.
Expected downtime is 2 hours, this post will be updated when the migration is complete.
Update: The new server is online and services seem to work just fine. Most nameservers should have already picked up the changes, but if you still can't connect (especially to the AUR) please wait a couple hours.
(If you want to check with host, dig or nslookup the new IPs are 184.108.40.206 and 2a01:4f8:160:3033::2)
