How to monitor third-party providers without alert fatigue

Watching every provider you depend on is easy. Watching them so that a provider incident produces one useful alert instead of forty is the actual work.

Map what you actually depend on

List the providers a request passes through: payments, CDN, DNS, email, auth, object storage, and the CI/CD you need at deploy time. Rank them by blast radius, not by how often you happen to think about them.

Tier the alerts

• Page for tier-one dependencies whose failure is customer-facing immediately: payments, CDN, auth
• Notify, do not page, for anything whose failure you can absorb for a few minutes
• Digest the purely informational, so it is searchable later without waking anyone

Correlate, do not multiply

A single provider incident can trip many of your own monitors at once. Group related signals into one evolving event, so a Cloudflare incident arrives as one alert with context rather than forty disconnected ones.

Sensible thresholds

• Page on a confirmed incident affecting a tier-one provider in a region you serve
• Suppress duplicates from the same incident
• Auto-resolve when the provider clears, so stale alerts do not linger
