Cloning a repository results in a timeout

I upgraded my OS to Windows 7 and installed mercurial, but I开发者_开发知识库 can't seem to be able to clone any remote repository. Windows Firewall is disabled and I don't have a third-party firewall. I even tried to launch the command prompt as administrator. No matter what I do, I always get this Operation timed out error. Any ideas?

c:\Users\Alfred>hg clone http://bitbucket.org/jespern/django-piston/ hgrepo
abort: error: Operation timed out

Hrm, what does the output look like when you include --debug and --verbose?

Also, what happens if you clone over ssh using this command line?

hg clone ssh://hg@bitbucket.org/jespern/django-piston/ hgrepo

It works fine when I clone it just now. I guess Bitbucket simply had a small problem. In such a case, the best reaction is to log onto the #bitbucket IRC channel on irc.freenode.net -- StackOverflow is not a very good support forum, especially for transient problems like this.
