Disappearing Servers

Loaded up BF1 this morning and the game played fine with no issues, just was hard to find many mixed/base game servers on the U.S. East Coast. 

This afternoon things started getting weird. I joined a queue to get into a mixed maps conquest server and progressed through the queue until I got to the second slot, after which I waited for 15 minutes. I decided to leave the queue and start it again to see if that fixed it, but then I couldn't find the server. It disappeared, poof. Gone. 

Then I thought "Well, people are still doing the blood and sand operation, I'll join one of those." There were three U.S. East servers available for that, and I joined one, got in, died a few times. As the attacking team took the last sector on Cape Helles, the screen went black and I was booted to the main screen with the following message, "The session has ended." I tried matchmaking to find another operations server, which failed. 

But what's really strange is that I can't find any regular servers now. The only ones that come up on the browser are hardcore servers, servers in other continents (i.e. Euro servers), and rented servers. 

What's going on? Why can't I find a regular conquest game?
