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. --- James M Keller
