Disqus stopped displaying

Disqus suddenly stopped displaying in the comment section on my posts today. I haven’t messed with anything on the site for days. The existing comments on my posts are displaying, as I know Disqus feeds them into my WP so that WP stores them as well, but the whole Disqus comments interface is not there, so it’s just the default WP comments display.

I did get a whole bunch of trackback spam posts today that had never happened since I implemented Disqus a few weeks ago, and I deleted them. Could that have had something to do with it? Is there a problem on the Disqus servers?

When I log into Disqus, all the comments for my site are gone. No unapproved, no spam, nothing. So not only is the plugin not displaying on my site, but the comments are all gone from Disqus’s database too.
