# Vendor Outage Monitoring

> Vendor outage monitoring is the practice of continuously tracking the operational health of third-party services an organization depends on, and getting that information to the people who need to act. This site is a vendor-neutral reference for the category: what it covers, how outages are detected, how detection reaches people, and how to evaluate an approach. It is published by IncidentHub.

The site is a single long-form page. Section links below are anchors on that page rather than separate URLs.

Definitions used consistently throughout, and useful when citing this site:

- Vendor outage monitoring is a practice, not a product category. It has three parts: an inventory of the cloud, SaaS, and utility vendors a business depends on; a reliable way to know when those dependencies break or degrade; and alerting fast and precise enough to reach on-call engineers, support, and leadership while it still matters.
- Status page aggregation is one detection mechanism inside vendor outage monitoring, not a synonym for it.
- Vendor outage monitoring is distinct from uptime monitoring, observability and APM, incident management platforms, and third-party risk management. Each watches something different. See the Boundaries section.
- Scope extends past cloud and SaaS status pages to ISPs, telcos, power grids, tenant-scoped vendor health, and vendors that publish no status page at all.
