I wonder if it’s just instances going down for a while, I know the one i am on goes down every now and then, and sometimes takes over a week to get back and running. I could see something like that causing the active users to fluctuate, especially if they wait a month before realizing their instance wasn’t deleted.
Wasn’t it a tunnel and a bridge? Thought they got 2 of the 3 with the last route having different gauge rails which still fucks with the logistics.
