NS_UNREACHABLE

warning

One of this domain's nameservers did not answer; the domain still resolves through the others, which is what makes it easy to miss.

Working today, and one change away from not working.

How we know

  • stale.test

    Delegated to a live nameserver and to 127.0.0.9, which has nothing listening. The zone exists on dns-auth on purpose: without it the fixture would be testing lameness rather than a dead server, and the domain resolving fine today is the entire hazard.
