How do server SDKs handle a failure to connect with Statsig?

Error initializing

In Server SDKs, you may see an error message indicating that initialization failed. Implement either:

1. bootstrapValues and the rulesUpdatedCallback, to provide the definition of your gates/experiments in case of a network failure, or
2. A Storage Adapter for a version of your gates/experiments locally (available in the PHP SDK, coming soon to others).

Error syncing

Server SDKs poll for changes to the definitions of your gates, configs, and experiments every 10 seconds, and for changes to ID lists every 1 minute. If one of these requests fails, the SDK retries a few times and may output a warning. The SDK continues to operate using the last known definition of your project and usually resolves issues by the next network request. During a complete Statsig API outage, the SDK operates offline using the last known set of feature gate and experiment definitions while retrying connections in the background.
