The recent problems and quirks were associated with their move to a new data center. They're still working things out:
Typepad will be conducting further maintenance this coming weekend to address lingering issues as part of the continued migration to the new data center. During a window from 9:30 pm U.S. Eastern Time on Saturday, October 29 (01:30 UTC on Sunday, October 30) to 9:30 am U.S. Eastern Time on Sunday, October 30 (13:30 UTC on Sunday, October 30), there may be periods where Typepad blogs are down.
I am seeing, and you probably are, too, an annoying intermediate delay when I load a blog page, with a message about checking security. I hope that will go away when the above work is done.
