There has been no notifications of server maintenance by Valve employees yet there are sudden crash in Steam servers which has been going on for quite a while now for me and I was wondering what would happen if this were to happen during the MRT.
I also found a website which tells us whether Steam is derping or not.

At the time this post was created, the website stated that steam was down and has 0 players online. The graph also shows that between 6(?) hours intervals there were huge number of player drop count.
