Out of all the servers currently on, only 4 of them are working, the rest have zero population and if you try to join them you'll get stuck on either "wait for host" or you'll be kicked shortly after getting to "please wait" with error message "connection was lost"

I can only assume this is something related to a server restarting as servers I was currently playing on restarted and now I'm unable to join them again.
I had the same problem all day. There were only a couple experimental servers populated, the rest all sat indefinitely on "wait for host" or I lost connection immediately after connecting. Tried for about 4 hours before I gave up and went back to the stable branch servers.
The devs are continuously working with the experimental servers (both 0.49 and future exp servers), so for this reason players will experience downtime and instability on the servers.
