# Snapshot Providers Snapshot providers are an optional fallback mechanism in case your app restarts, and for any reason can't reach Toggly to download the latest set of definitions. Toggly is highly available, and features are held in memory in your application for the lifetime of the application. During app startup, features are loaded from Toggly with a 5 second timeout; if Toggly can't be reached (ex: your app doesn't have internet during startup), then features are loaded from the snapshot, and normal feature updates resume as soon as your app reconnects. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
