i think there was a webpanel update last night.
"We will be performing some maintenance on our central databases beginning Wednesday, June 20 at 10PM PDT and ending 4 hours later at Thursday, June 21 at 2AM PDT. The expected downtime within this window is 2 hours. This will bring the DreamHost Webpanel, as well DreamHost-provided Squirrelmail offline."
I cannot access my squirrelmail, maybe thats causing it.
