Domains and DNS

DNS propagation - how long it takes and what really happens

DNS propagation is not one global switch, but cache expiry across many resolvers around the world.

When this matters

One person may see the new server while another still sees the old one. This is normal when TTL and resolver cache differ.

What DNS propagation means: TTL, resolver cache, A, MX, NS records, tests from different networks and migration risk.

Practical checklist

  • lower TTL before migration
  • check records from several resolvers
  • do not remove old mail immediately
  • after the change, watch forms and logs

What to prepare before contacting support

If you need support, include the domain, account name, time of the problem, exact error message, recent changes and one example URL or mailbox. This lets support check DNS, SSL, mail logs, PHP, database, backups and application configuration faster.
