Why won’t Fastly clear my cache after I update prices or content?

On Adobe Commerce Cloud, Fastly is the full-page cache. If edits don’t show, the usual causes are: surrogate keys not being purged, a stale-while-revalidate window, a broken custom VCL snippet (often throwing a 503), or the Fastly module not being configured for soft-purge. We audit your Fastly setup, fix the VCL or purge logic, and confirm that price, stock and CMS changes invalidate correctly.
