Two-Signal Method to Quickly Identify Third-Party Provider Outages

When a production system fails, engineers face a costly question: is the fault internal or caused by an external provider like AWS, Stripe, or Cloudflare? OutageDeck founder Kerolos argues that neither reading a vendor's official status page nor running synthetic probes alone is sufficient to answer that question reliably. Official status feeds reveal only what a provider has formally acknowledged, often with delays and gaps in scope, while synthetic checks can fail due to internal issues unrelated to the upstream vendor. Combining both signals creates a simple triage matrix — for example, an operational status page paired with a failing probe points to an internal investigation, whereas both signals showing an incident strongly indicates an upstream dependency failure. OutageDeck offers a keyless read-only API that lets teams programmatically query normalized status data across 172 providers to serve as one half of this two-signal monitoring approach.
