The number of seconds that intermediate servers can cache a DNS response before querying again.
Why it matters
Determines how quickly a DNS change reaches users. This can mean the difference between five minutes and a full day of downtime during a migration.
What's missing without it
With a high TTL, a record change can take up to十几个 hours to propagate — some users reach the old server, others the new one.
When it is used
Before every planned server migration or change in email provider.
How we use it
TTL 3600 means one hour. Before a planned change, it's wise to reduce it to 300 to speed up the switch.
