Description
Since yesterday many paths of the form https://esm.run/{name} and https://esm.run/{name}@{version} have started breaking, instead serving a 421 response with the body:
Requested host does not match any Subject Alternative Names (SANs) on TLS certificate [4e88d7db0fa92f185d522e0448683816c7a71e4568d87f65ec4a42f984f5c991] in use with this connection.

Two of many examples:
Caching may play a role, as e.g. https://esm.run/d3 still redirects.

No response
Fastly deprecated a TLS setting we were using which resulted in this unfortunately outage. The issue is now permanently fixed.
