Disqus

Reports of it being out intermittently for people still. My big suggestion is that if you are on twitter, tweet your problem @disqus and @disqussupport.

It isn't that I'm asking you to fix my problem for me, it's that if they respond they'll want you to answer specific questions about your setup that I can't answer since I can't duplicate the problem myself.

Otherwise check if it's an ISP problem (Try on your phone using cell data, not wifi).
