Blogspot has a warning up on the "manage posts" page: "Scheduled outage at 4:00PM PDT."
It's been up there for, oh, six months now. I think they just leave it so whenever there's an (unscheduled) outage people will think, "10:23 a.m. here in New York must be 4:00 p.m. Pacific time. Therefore I have no reason to complain. I love you, Bogger!"
