Daily volume could just be more bluray high quality downloads with people with better internet. And not neccesarily larger number of people right?

I would be pretty surprised if the quality of rips since 2017 would account for a 20x increase in traffic.

Most of the rips are probably the same-ish size. But there are definitely now a lot of incredibly huge rips. A 13-episode season of television that's like 80 gigs. It's an additive load, and while it's not that regular, it could have a massively outsided impact.
