From the ABA forum:

Archery Forum, and TBGA is hosted on the same servers as AF:
"Archery Forum could be down a while. Out host's network has been badly attacked.
"Engineers are at DC working on restoring services asap. Very deliberate, coordinated & malicious attack on DIT network the cause. No ETA yet"
This was posted on the 16th of this month and are still down now. I had no idea until minnie asked for information about one of the forums over at AT today. Bit of a coincidence or what?
