Primarily used for terraform configuration.
Fastly checks the two Warehouse processes separately:
Applicationchecks/_health/web, routed toweb.Application_APIchecks/_health/api, routed toweb-api.
Fastly sends /simple…, /pypi/…/json…, and /_health/api (with optional
/… suffixes) to the API backend. Matching ignores case, just like ingress.
Keep both sets of rules in sync. Uploads use a separate service and are unchanged.
