We are currently experiencing elevated 5xx errors from our CDN provider. You can track the upstream issue at the provider’s status page: https://www.cloudflarestatus.com/ This affects CDN endpoints used by all server SDKs to download configuration updates. SDKs using fallbackToStatsigAPI (where supported) or a local DataStore will continue operating, but may not receive the latest configuration changes until the CDN recovers.

The engineering team is currently investigating. We are seeing high unavailability from 4:33PM PST, but mostly recovered by 4:38PM PST. Client SDK Initialization failed to initialize during this time period for a majority of requests, and event logging calls failed as well. However, we expect that most events will be recoverable due to SDK level retries. Mitigated: 11/06/2025 16:40:00 GMT-0800 (Pacific Standard Time)
