Change made, not everyone sees it yet

DNS propagation depends on TTL plus resolver cache. Patience and the right tools.

Try this first

  1. 1Verify change at the authoritative NS with dig +short @ns1.provider.nl name
  2. 2Compare with public resolvers (1.1.1.1, 8.8.8.8) after minutes
  3. 3Use dnschecker.org for worldwide sampling
  4. 4Allow 1x TTL for broad propagation, longer for ISP resolvers

When to bring us in

Past 24h drift, check if an old NS set is still active somewhere.
