So, about an hour ago, MoveOn.org sent out an email saying that they'd posted the finalists in the "Obama in 30 seconds" contest/campaign for rating. About half an hour after that, the site obamain30seconds.org seems to have died.
Anyone want to venture a guess as to the probability of attack versus load issue?
Edit: seems to be back up after about 20-30 minutes of down time. Also, it looked like moveon.org was down for the same time period.
