Fastly is an edge-cloud CDN used by many high-traffic sites and apps.

The source-code fingerprint

Assets referenced from *.fastly.net / *.fastly.com hostnames.

Likely false positives: Sites that serve Fastly via a custom (CNAME'd) domain won't expose a fastly hostname in HTML.

How this works

The headline distinguishes candidate upper bounds (index prefilter), estimated matches (a projection from checked samples) and verified matches (an exact count established by the engine). The index contains 131,219,565 homepage documents, one homepage per hostname, including subdomains. The source index was promoted 2026-09-22 and follows a quarterly rebuild schedule. The sample date is when this query was checked against the stored index, not a new crawl of each example site.
