Three ways to put a folder on localhost when you need to test something quickly.

Backs off on each failure and adds jitter, so a recovering service is not hit by every client at the same moment.

fetch has no timeout of its own. AbortSignal.timeout is the short way to give it one.

Backs off on each failure and spreads retries out, so a recovering service is not hit by every client at once.

unknown forces a parse step rather than letting an any spread silently through the codebase.

Splits DNS, connect, TLS and first byte apart, which tells you which one is actually slow.

Traces a redirect chain to its destination without downloading the body.

Invoke-RestMethod parses the response for you, so no ConvertFrom-Json step is needed.
