For a couple of days, I couldn’t get into a BTB game. I’m just stuck on the " Searching for players" or " Searching for more Players" screen and never found any players.
For me, it seems like BTB works during the day with 2-3 minute waits to find players, but then late at night (around 1:00am to 2:00am (USA Arizona time)) it stops working with “Searching for more players…” forever. Then around 9:00am to 10:00am it starts working again (again with 2-3 minute search times).
During the time that it does work I get games one right after another, I could play 30 BTB games in a row no problem if I wanted to.
Its also not my internet because I have 45mbps upload and download (speedtested), open NAT, 3ms latency, 0% packet loss, all with my Xbox One console in DMZ through my router (which opens/forwards all the ports).
This is a huge problem, especially for other countries where it wouldn’t be working at prime gaming times (if it isn’t just me experiencing this).
Every other playlist including H2A, Team Slayer, Halo 3, etc all work fine though (even the times when BTB is not working).
This is just my own experience though, it might be different for everyone else.
