I have found Comcast rate shapes or resets long running encrypted sessions such as https. At $DAYJOB I had to set our SSL VPN system to re-key via new-tunnels every 5 minutes to keep it under their threshold of what looks like seven minutes for a tcp session. After that the sessions appeared to rate shape down to 128kbps. It may also only kick in during local POP congestion. I am assuming this is DPI trying to do peer-2-peer mitigation.
We don't have such network practices and are required not to under Open Internet rules. I have no idea what was causing your VPN issue - I can use my corporate VPN for hours or days at a time with no issues. Happy to assist off list if you like. Jason
