I just noticed this morning that the MGID link exchange widget wasn't loading up on Wopular's subpages, so I temporarily disabled it. The widget was keeping those pages from fully rendering.
I checked on their twitter page, and there's no mention of the outage. I checked Google News and searched Twitter, but found no mention of the problem. When I went to the MGID site, I noticed it was having trouble loading images and other modules on their right sidebar. That's when I've confirmed that the problem was on their end.
It's fine now after I don't how many hours of downtime.
Still, it'd be nice if they had a "status" page like AddThis or Linode that lets their publishers know what's going on.
