Understanding TTL (time-to-live)
What is TTL or Time to Live?
TTL, or Time-to-Live, is the length of time for when a zone file is set to expire. This is usually expressed in number of seconds.
What is the default TTL value?
The default TTL is 42300, or 12 hours.
What will be the new length of time if I lower my TTL value in the AccountCenter?
If you lower the TTL it will set to 300, or 5 minutes.
How long do I have to wait for the lowered TTL to take affect across the internet?When you lower the TTL to 300, or 5 minutes, it will take effect on thepacific.net servers immediately. But for the TTL to propagate across the internet you will need to wait from 12 to 48 hours. It is best to lower your TTL 2 days before you plan on changing your DNS so the change will propagate across the internet in the fastest possible way.
What if I require a custom TTL value?
If you require a custom TTL value, please submit a support request along with the requested TTL value, and why it is required.
When would Lowering my TTL Value be useful?
