Most sites set the absolute minimum TTL for every record, for no reason. There’s a lot less caching than you’re thinking.

- cm2187 6y agoNo I see some services failing that have a TTL of 1h.
- qeternity 6y agoEh, what? There are many good reasons to have low TTL DNS...this exact outage being one of them. Update your records to go direct to your servers, and not through Cloudflare and bam you’re back up. Doesn’t work if your TTL is 86400
- unilynx 6y agoDoesn't help as cloudflare wants you to host their name servers with them, so you can't flip any records if the DNS itself is in trouble, like it is now And changing DNS servers often takes many hours (or days, if .net is involved apparently)
