i don't know what happened, but i use Opera 11.60, and when the site went down yesterday, i was unable to log back in and kept getting "site is temporarily unavailable" (with DC masthead) all day yesterday. i woke up this morning and refreshed the page and still got the "unavailable" page (with DC masthead). only when i tried to visit the page using another browser did i find out that the site was back up. i also restarted Opera and it worked fine then.
i keep my browser open all the time, and maybe that was the issue. anyway, just a heads up that maybe other people are in the same situation and still think the site is down (yeah i admit it, i was starting to panic). maybe a reminder to restart browsers on Twitter or Facebook wouldn't hurt.
