Network DNS propagation issues

#1

About hour ago I’ve added new domain to cloudflare services & updated DNSes for the domain.

All popular DNS servers got new NS records within seconds, while my default 1.1.1.1 server (waw02) still responds with old records.

dig +short CHAOS TXT id.server @1.1.1.1 -> "waw02"

dig NS blockchainassociationinfo.com @1.1.1.1

Appears to have updated for me, are you still experiencing incorrect resolution?

I also find that Cloudflare DNS is really slowly compared to Google in DNS propagation. In facts, I pointed a domain to Cloudflare and changed the IP of the A record, Google see the change already but Cloudflare DNS not. Isn’t supposed that Cloudflare DNS should see first Cloudflare changes?

I’m thinking to swich back to Google DNS just because that.

:wave: @laszlo.jr.demeter,

That’s not exactly how DNS works. Resolvers cache responses based on the TTL specified by the authoritative nameservers for the record in question.

Hi Oliver,

I know, but even with TTL set to 2 minutes it took like 4 hours to propagate. And then, the cache refresh page didn’t works.
