Failure in name resolution sounds like something went odd with the
network setup. It would be the host networking stack and the general
network setup that would be responsible for that rather than bitbake
specifically.

I assume you're using a FQDN which needs DNS resolution from a remote
DNS server? Any local caching of DNS?

It does sound like the DNS server became unreachable for a short period
and there wasn't a local cache. Its also possible we resolve the name
often enough (in many different processes) to trigger some kind of
repeat lookup protection on a DNS server if you have a more paranoid
security setup.

A static IP, or a static entry in hosts would likely work around the
issue, or simply using an IP address.
