Chris -
Sounds like you got your answer; it doesn't matter.
All that aside, looks like you should be on par with europe:

I get odd stuff with some streaming media too, but my guess is it's the servers.
Your system is about double mine, so I don't think that's it and if you get the same results at work, then that probably rules out your home service provider.
