Twitter blocked in China?

Uhoh.

This is exactly what Safari looks like when you try to open Wikipedia or, in the past, blogger.com. Now this shows up when I try to open Twitter. I just wrote something on Twitter, then BAM! gone. Hope they're not blocking everybody's new web 2.0 darling now, too! They already killed myspace.com and are forcing everyone to go to myspace.com.cn...
