We previously experienced a service interruption caused by a global Amazon Web Services (AWS) outage affecting CloudFront services, which began around 09:19 BST on July 16, 2026. This caused downstream elevated error rates in our authentication provider, which connects Model ML to our customers' identity providers (IdP).

No customer data was impacted. The outage affected only access to the Model ML web application and did not compromise data security or privacy.

AWS has resolved the underlying CloudFront issue as of 12:23 BST on July 16, 2026, and normal access to Model ML has been restored.
