Resolved
All issues resolved, you can go back to playing!
Monitoring
We have just reverted a change affecting matches starting at 19:28 UTC+0, December 19th.
Matches should now be properly resulted and, therefore, operational as expected. Our teams are monitoring the situation as it quiets down.
Investigating
We are aware of issues with some CS2 matchmaking matches ending on a TIE which should not be the case.
Our teams are aware of the issue and are coordinating a fix for it.
