As of this evening I've discovered that a couple of regular sites I visit are suddenly not coming up. This includes Wikipedia, Variety, and QuartertoThree. As this is occuring on my PC as well as my tablet, I know its not browser specific. The message I'm getting is rather odd as well. For some reason it's a Yahoo!-404 Not Found message, which I've not seen before. These websites are up and I can get to them via proxy. A few months ago I had a similar issue that lasted about a day or so with Broken Forum. I went through tech support with my ISP at the time, and while they weren't able to get it resolved right away, I did get the impression that it might have been at their end. Any ideas? I did just change routers, but that was a couple of days ago and there were no issues prior to tonight.
