You may just have noted that DV was down for a few days. While I poked at the issue a bit I did not find the problem until today, Saturday. I finally had time to really sit down and figure out what was wrong.
I probably received some e-mail explaining that there would be a change. I just ignored it in the usual torrent of messages I get every day.
Server names updated in the setup files and a few PHP scripts, it appears everything is back online. Sorry for any confusion!
