said by 34764170:Comcast is known for having their transit ports to TATA being saturated and this is far from a new issue.
Having to chart these issues for ~80k VPN users at work, I can tell you there is congestion between TATA and Verizon, TATA and Centurylink, TATA and TimeWarner, TATA and Comcast.
There's a commonality there that is not simply Comcast running their connections hot.
I colo servers for personal/non-profit use in Chicago and Dallas, and I've had to play these games with moving my servers because the DCs had carriers that ended up using TATA as intermediate transit to Comcast & TWC folks.
It sucks, and sadly it's not going to get better anytime soon.
