I also couldn't access DDD all day Thursday or earlier today, but it seems fine now. I first noticed it when I was going through e-mail, and the graphics in the e-mails from DDD wouldn't even load in Eudora (while all my other HTML e-mails from other places were fine), so I tried going to the actual site, with no luck. (Neither IE or Firefox worked.)
But, as I said above, no problem now.
