20 May 2026, 20:19 UTC

Our engineers have confirmed that the Fastly API (api.fastly.com) has been fully restored. Customers may have experienced elevated 503 errors, increased timeouts, or failures on API calls and Terraform builds from approximately 18:35 to 19:37 UTC.

As a side effect of the API degradation, the following areas were also impacted during this period:

  • Next-Gen WAF (NGWAF) rule and configuration updates may have been delayed in taking effect
  • Fastly account sign-up may have experienced disruptions
  • Fastly Support Portal functionality may have been affected

Service has been fully restored. Affected customers may have experienced impact to varying degrees and to a shorter duration than as set forth above.

This incident is resolved.
