Some websites are slower on 91
Certain websites are much slower on 91 (same on my laptop, I compared 90 vs 91), for example http://www.tailfeathersnetwork.com/community/ (also logging in and out) and https://www.unexplained-mysteries.com/forum/ . Why?

Tried all of that, nothing worked. I do not think this is a problem on my end, because it started happening on two devices as soon as I installed version 91 yesterday.

I've tried ipconfig /flushdns, nothing.
