I was occasionally having problems accessing YouTube videos over my FIOS connection. I had 75 Mbps down, but YouTube videos sometimes failed to play after about 5% of the video had downloaded or they would only download at 144p (it reminded me of RealVideo from the 90s). I read reports from other users that showed up to 50% packet loss over FIOS to YouTube servers. Those users also reported that if they VPNed into their work network, they were able to view YouTube videos just fine. That was the straw that broke the camel's back and I switched to Comcast and cut the television cord. While their service isn't quite as good, I got a really good deal. The only thing that annoys me is that when I VPN into work, my connection goes from 30 Mbps to 750 Kbps. Since I primarily use the command line, that is tolerable, but it does piss me off that this wasn't well-communicated to me before I signed up.
