the issue was that june-july-august my internet usage was 200 gb and suddenly this munth it is nearly a terabyte so far.

first, given past experience, i would sugest it is at least 10% chance it is a comcast problem, such as a bug in their modem causing resends of data or something. no idea how to diagnose that or prove it. once they closed the pinhole required for dynamic ip requests, nobody I could talk to in sujpport would listen to me (this was back when i was studying this stuff, getting my CNA). but over 2 weeks as more and more people lost access they eventually figured out. I must have been one of the fierst.

I did say "i wasn't doing anything different".

may have been an untruth. This was the first time I left a window open in discord, connected to at least 4 servers. I don't think any of them had audio or video channels open, but i know I was accused of consuming cycles on the server of one of them many years ago.
