Why DNS changes take time

When you change a DNS record, every resolver on the internet keeps the old answer until its cached copy expires — that lifetime is the record's TTL.

• Our default TTL is 1 hour: most visitors see changes within the hour, many within minutes.
• Planning a migration? Lower the TTL to 5 minutes a day in advance, switch, then raise it back.
• Nameserver changes propagate at the registry level and may take up to 24–48 hours worldwide.

Check propagation from your own machine with nslookup yourdomain.com or an online propagation checker.
