Question 1

How long does DNS propagation take?

Accepted Answer

Typically 1-48 hours depending on TTL values. Lower TTLs mean faster propagation. Most changes are visible within 1-4 hours on major resolvers like Cloudflare (1.1.1.1) and Google (8.8.8.8).

Question 2

Why do I see different results in different locations?

Accepted Answer

Each DNS resolver maintains its own cache. Servers with the old record cached will keep serving it until the TTL expires. Different resolvers update at different times.

Question 3

How can I speed up DNS propagation?

Accepted Answer

Lower the TTL on your records before making changes (e.g. to 300 seconds). Wait for the old TTL to expire, then make the change. The new low TTL means caches refresh faster.
