I pay quite a bit to have fast internet, and for the most part, I'm pretty satisfied. Over the last few years, however, I've found that on a rare occasion FIOS inexplicably has problems loading pages. When I try a "SpeedTest" I still see speeds north of 35mpbs! So why can't I load a YouTube video? The answer is simple, because FIOS and many other ISPs by default assign you to terrible DNS servers. They're terrible for two reasons: 1) if you incorrectly type a URL, you get an search result/advertisement and 2) they're often slow and cause pages to not load at all.
