The NTP Pool Project is a big virtual cluster of timeservers providing reliable and easy to use NTP service for millions of clients.
The pool is being used by many millions of systems around the world. It’s the default “time server” for most of the major Linux distributions and many networked appliances.
While Network Time Foundation is able to offer some support to the NTP Pool Project, it is not an NTF Project. Please visit the NTP Pool Project website for more information.
