Re: Long delays restarting unbound if Red is down

That’s precisely the problem, Michael. Everything works fine, until something (like an internet outage) prevents you from reaching the DNS servers. Then, when you reboot the router as part of a troubleshooting process, it takes forever while unbound flails about.

In this instance, we were replacing a failed router, and someone had misconfigured the red interface settings, so we were modifying those settings in setup. It took us a while to figure out what we were doing wrong, so we ended up having to wait over and over again as unbound tried to restart and failed. We were the problem, but unbound made it a real hassle while we worked to figure out what we were doing wrong.

Shouldn’t it have a reasonably short timeout for when the DNS servers are unavailable?
