We’d like to disable all DNS for a single domain temporarily to make sure all is good before we decommission the domain entirely.
One option is to switch away from Cloudflare via the registrar but that involves DNS propagation delays - is there an immediate way to switch DNS in and out on the Cloudflare portal? “We are under attack” still allows DNS to resolve.
We want to switch off DNS to see what breaks (clients may be using entries that we aren’t aware of) and be able to switch it straight back on if needed (to then diagnose the problem)
Redirecting the name servers will take too long to undo… is there a way to turn off the DNS redirection temporarily?
You can’t “turn off” DNS, other than by deleting DNS entries or pointing your domain to blank name servers.
It doesn’t take long to repopulate DNS from a BIND file. If you want to minimize potential outages, switch TTL down to 2 minutes. If it’s an entry, it’s stuck at 5 minutes.
