We've been working on the issues we're seeing in EUW, however unfortunately we've reached a point where we believe an emergency platform restart is required.
ETA is around 30 minutes although may take longer if issues persist. During this time players will be disconnected from platform, and ongoing games will end with no win/loss conditions. After this, logins will be disabled while we finish the platform restart and check the health of the environment.
We'll keep you guys posted on any updates we have after this restart.
