NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

Please see the NTP Security Notice for vulnerability and mitigation details.

Donations Wanted

The NTP Public Services Project relies on contributions from OurDonors to support our operations. Please see DonatingToTheProject for more information about making a donation to support the Project.

Hardware Contributions (components and complete systems)

The list below is quite outdated, and we really have better things to do than keep it up-to-date. While I think we'll be rewriting this page soon, who knows when that will happen; if you would like to offer equipment to us, please just let us know. And cash donations are even better.
