The normal way to handle these things is to use a) reliable network
connections, or b) multiple interfaces.

What Squid is this?

Things should go back to normal when the interface actually comes back
up again.

If the interface is up, the parent proxy contactable and Squid still
sending out the error pages you need to take a good look at those error
pages and see *why* Squid thinks they are still valid. Probably turn
negative_ttl down to an HTTP compliant 0 seconds as well.
