Half my public infrastructure is down. It could have been a 100%, but I separated private and business systems last month. Lots of people use MT because their email and DNS logic is solid. So this is pretty serious for them. Media Temple was broken into a while back via a Wordpress bug and people wonder if this is related to that event (HN really needs a "related news" button).

MT also did a hardware upgrade yesterday. So they are probably a little stressed right now. http://status.mediatemple.net/
