Summary AI Generated
A WorkOS authentication provider outage prevented new sign-ins to Prefect Cloud via SSO, Google, Microsoft, and magic-link/email for approximately 1.1 hours. Already-authenticated users, API keys, workers, and flow runs remained fully operational throughout. Sign-in success rates gradually recovered as WorkOS restored service, with no manual intervention required on Prefect's end.
An ongoing outage at our authentication provider, WorkOS, is preventing new sign-ins (SSO, Google, Microsoft, and magic-link/email). Users already signed in are unaffected, and API keys, workers, and flow runs continue to operate normally. We're monitoring WorkOS's recovery; sign-in will restore automatically.
