Request for information: ISPs and P2P throttling

When does the problem occur: This didn't start happening until 2.3. It happens randomly. The game goes to a crawl. This happens in short bursts. 10-15 seconds of running smoothly and around 5-10 seconds of this extreme choppy 1 frame per second lag. FF14 is the only game that this happens to. I can play for several hours without this happening, or it could happen pretty much as soon as I log in.

I hope you guys are able to sort this out. I have 9 days left of membership. If this keeps happening I probably won't resub. I really enjoy playing but it's honestly to the point where I can't play because of the lag.
