link validator failure is unrelated:

## HTTP failure response

I wonder if we should remove the link validator from PR validation and instead run it nightly/weekly to monitor for longer-term failures?

I strongly favour taking link validation off the main builds and have it run as a separate standalone run. It is just far too brittle.
