Subject: [PATCH] feat(dns): Switch minimum TTL to 20 minutes
This patch changes the minimum TTL for self-hosted DNS to 20 Minutes in
order to fight against traffic spikes that seems to accure roughly every
15-20 minutes. This might reduces the number of spikes and request
timeouts.
This is an experiment, there is no proper research done whether this
works as expected.
