Why is my provider outage breaking my app?

Usually because your app is too dependent on the provider being instantly available and doesn’t have enough resilience when that dependency fails.

Common reasons:

• Synchronous calls to the provider: your app waits on the provider in the request path, so if it’s slow/down, your app is slow/down too.
• No timeout / retry policy: requests hang or fail in ways your app doesn’t handle gracefully.
• No circuit breaker: repeated failing calls keep piling up and can cascade into an outage.
• Single point of failure: one external service outage becomes your app outage.
• Tight coupling in core flows: authentication, payments, messaging, etc. may be designed so the app can’t proceed without the provider.
• Missing fallback behavior: no cached data, degraded mode, or alternative provider when the service fails.
• Resource exhaustion: blocked threads, connection pool starvation, queue buildup, or retries causing thundering herd effects.
• Poor error handling: provider errors aren’t translated into controlled app responses, so they bubble up as 500s.

What to do:

• Set short, sensible timeouts
• Use retries with exponential backoff and jitter only when safe
• Add a circuit breaker
• Provide fallbacks/degraded mode
• Cache what you can
• Isolate dependencies with bulkheads
• Make the app tolerate provider failures in non-critical paths
• Monitor provider latency/error rates and your own saturation metrics
