DNS resolution errors affect more than just wget (have seen curl and ruby bundler and git all fail too) and it fails to resolve names in and out of openstack.org.

Infra has increased TTLs on openstack.org records that are hit by jobs to reduce the number of lookups that should be necessary (git.openstack.org tarballs.openstack.org and the mirrors). We are also in the process of updating the local unbound config to resolve against opendns first then fallback to google instead of using google dns only. Hopefully this results in much happer DNS.

This ended up being a bug in our unbound config. We were using ipv4 resolvers in OSIC which forced all Internet bound ipv4 traffic through NAT. This NAT was unreliable at times (because well its NAT). Fix was to only use ipv6 resolvers if we have proper globally routable ipv6 interfaces.

Also we no longer have an osic cloud so ya.
