Jitsi Official hosted https://meet.jit.si/ rate limit? Production ready?

We have an app that breaks a large group of people into smaller groups (10-20 people). We need to know if https://meet.jit.si/ can handle up to 300 simultaneous hits from different clients (served by our apps server) at once? We did a test on Friday but we were not sure if it was jitsi that was the bottle neck or our own application. So. Is it recommended to use the official jitsi meet hosted service in production? if not whats involved with hosting jitsi on our own GCP (google cloud project) Thanks!
