I posted this awhile ago which has some more info. I appreciate that you're actually doing the research. I posted some contact info for Verizon in that thread as well, if you want to look into it. I have had no success. Last night was particularly bad, but that seemed to be for everyone. The traceroute I ran actually had congestion on Ormuco's end (the ISP SE's servers are using). It's quite possible Ormuco was having a hiccup. Verizon in particular is a weird case because we (such as myself) don't always pass through Level3, but Alter.net, which is owned by Verizon itself. Like I said, last night could very well be a separate issue, but in general Verizon customers will probably still have problems.
EDIT: In addendum, the reason there has not been a direct "the fault is with X" response is probably due in large part to contracts. SE cannot badmouth Ormuco, Ormuco cannot badmouth Level3, etc etc down the line of bullshit that is sad but true. Doing so could cause them to lose their provider, which knocks everyone completely out until they find a new one. SE honestly has been pretty open about issues involving the game itself, but this goes a bit further than that. I'd like to believe that if the problem was the server itself, we would know about (they have come clean about this in the past).
EDIT again: Also, I have personally made SE aware of the issue with throttling and I would like to believe they are doing all they can. Big companies like Verizon have big egos, so they are quick to say "It's not my fault, it's yours!" There is a possibility that it is a similar issue as Netflix, what with packetsniffers looking for game data and saying "fuck that, who cares?" I'm not positive, my theory is that it's simply Content Delivery Networks being absolute shit in the U.S. What I've done to help is post publicly all over the place, called Verizon many times, called SE many times, etc. AFAIK that's the best we can do.
