"Waiting for www.faunaads.com..."

I've been having this intermittent issue for a few months, and Fauna is the only site I frequent that seems to be giving me this problem. Sometimes, when trying to load or refresh a page, I'll get the green background and the Fauna logo in the upper-left corner of the page; but that's all that loads. When this happens, there's always a small notification on the screen that says "Waiting for www.faunaads.com..." Refreshing doesn't help, nor does closing the browser and reopening it. The only 'fix' that seems to work is clearing out cookies and cache. I currently use Firefox; but IE was no better. It's also happened on both my former desktop as well as my current laptop.

In the several months that I can remember this happening, it was generally for fairly short periods of time - usually just a day, but sometimes up to a week. The frequency with which I need to do my 'fix' is pretty variable, also. Generally, I'd get a couple of hours before I'd need to do it again. Today, it's been about 30 minutes in between fixes. Despite knowing that I'm pure walking bad luck; I think there's gotta be others having the same issue. Anyone?
