That's not surprising. I'm seeing the same at my data-center. They're running several 100Gbit connections, but they also host a bunch of infrastructure for Netflix and Hulu, and they told me that "due to the significant amount of traffic to several of our customers, you may see bandwidth impacts." I got another ticket this week that said they're recarving up their bandwidth to limit those two in particular. Going to be interesting to see how that goes.
