Is appengine.google.com blocked from China

[wei]

I tried to access appengine.google.com form China, but failed. I read
a post that it was blocked in Aug, I don't know if it is still true.
If so, anyway to get around or fix this problem from Google?

I'm in China right now and can access it. The access comes off-and-on,
about 30 minutes off, hour on, back and forth. It might also depend on
where you are in China seeing as some internet providers seem to block
websites locally for various reasons. (It might also depend what
gateway you're accessing the outside world through, from what I've
read there are a handful of gateways that control access and they
aren't always consistent with each other.)
