Summary: They’re slowing down access to AWS. If you host your application there, your readers and users get lower performance. Their reason, presumably is that they want Amazon or Netflix to pay to get the performance back (Netflix runs on AWS).
I had FIOS for a year when I lived in lower Manhattan. It was wonderful. Symmetric bandwidth. The same speed up and down. This is the Internet as it was meant to be.

Until today I envied anyone who had FIOS. Today, I think they’re crashing their good name.
This is an outgrowth of a recent court decision that says they can do this.
But they probably will re-think it if it gets them the bad name they deserve.
