Resolved
Open browser tabs with old logins to the Intercom app may be causing ongoing login/logout churn - closing old tabs or restarting web browser will prevent this from happening.
Monitoring
Earlier today at 10:10 UTC many teammates were forced to logout and log back into Intercom. In a small number of cases, server side rate limiting impaired logging back in, causing login loops. We've resolved this issue as of 13:00 UTC. Apologies for any disruption.
