  1. identified Jul 16, 2026, 09:48 AM UTC

    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.
