The game client crashed (Rendering Device Lost pop up under the client window) and I was unable to rejoin in time. I believe that there was a 1:30:00 “Cool-down” for this which was not the usual 10 minutes. I waited it out but, after the cool down expired, competitive play remained unavailable. I checked for any outages, but there was none, and some of my friends are online.
Edit: I found something interesting at: Lost Sr and banned, not sure why?, which appears to be the case (See WyomingMist’s reply) How do I know for sure why I was suspended or banned? I switched PC’s (My older one is slower / more stable but for extended play gives a normal playing experience)
