Incident Update: We resolved an issue impacting the public API

Between 08:37 and 09:51 UTC, a subset of requests to the Platform API (API v2) failed with HTTP 500 errors. Endpoints including /v2/slots and /v2/bookings were affected, as was API key authentication, which caused some requests to fail before reaching the endpoints.

The cause was a loss of network connectivity between our US East compute region and the database. Database connections from that region timed out at the socket level, causing queries to fail. Traffic served from our EU region (fra1) was unaffected throughout. No data was lost or corrupted, and no customer data was exposed — failed requests returned an error rather than an incorrect result.

Connectivity recovered at 09:51 UTC and error rates returned to normal immediately. We have confirmed zero database timeouts since. We are following up with our infrastructure providers to establish the root cause of the connectivity loss and to reduce time-to-detection for region-scoped failures.
