Some of you may have already updated and are now getting the issue of outdated server. Some of you haven't yet.
I will be looking into the update and what it means for the CG servers to get them updated over the next few hours. Sometime tonight I will test it on the dev server for OCRP and once I know it works without issues I will be shutting down the servers for the update. By then most people should have received the update and been unable to join anyway. So if you see the servers offline know that we are updating to SteamPipe although we don't want to.
TL;DR: If you see the servers offline later today, don't worry.
