Given the volume and ephemeral nature of the nodes we are running jobs on, we're interested in raising the minimum TTL to ensure we're not needlessly querying domains all the time. Some domains such as github.com or fedoraproject.org have low TTLs and we suspect there is a correlation between their low TTLs and the fact that we're seeing increased DNS lookup rates for these domains.
