What are the best focused sources for tracking outages and security incidents?

I’d follow the status pages and changelogs of the specific vendors you rely on, rather than trying to track every incident everywhere. For broader monitoring, tools such as Changedetection.io can watch pages that do not provide feeds, and a self-hosted RSS reader can organize sources by provider, vulnerability, or incident type.

Start with the official status pages for the major providers and services you depend on. Many expose RSS or Atom feeds even when the link is hard to find—for example, some have a /history.atom endpoint, while others provide feeds through their status-page system. These updates usually appear before broader news coverage, so putting them in a feed reader is much more useful than monitoring social media.

General technology news sites can be useful for context, but their coverage is inconsistent and often delayed. Official provider feeds plus a curated security source tend to provide a better signal-to-noise ratio than relying on broad social-media timelines.

For security-focused information, the CISA Known Exploited Vulnerabilities catalog is a strong, relatively low-noise source and offers an RSS feed. Microsoft Threat Intelligence is another useful source for security reporting and incident context.
