Redis cache issues

[Bruno Blanes]

Good morning folks,
I noticed that Unbound will not start if Redis cache is configured but unreachable, can anyone elaborate on the design choice behind this?

Also, I've noticed that when the cache connection is refused, Unbound works just fine querying the root servers and returning the answer, however if the connection timeout, aka Redis server shutdown, all queries timeout rendering my DNS useless.

Is this a config issue on my side or also by design?

Best regards,
Bruno Ortega Blanes
