Wouldn't it be trivial for ISP to determine site via traffic patterns?
Even if you're using a VPN, shouldn't an ISP have access to more than enough data to determine that X packets of roughly Y size, sent with roughly Z timing is 99% likely to be S service? They have the training data...Am I fundamentally misunderstanding some part of how ISPs work?
the MTU (maximum transmission unit) is usually 1500 byte. most pages have more content. The only thing they can distinguish is videos, because video needs a kot of bandwith over an stable connection.
That's what deep packet inspection do ,but i think it gets expensive
