Santa Rosa, CA, March 31, 2026 - EndRun Technologies, a leading provider of precision time and frequency solutions, announced the release of the Sonoma D24 and N24 GPS Network Time Servers. These fourth-generation time server appliances provide four Ethernet ports for added versatility to securely serve time to independent enterprise network segments.
The Sonoma D24/N24 take maximum advantage of the quad-core processor to serve network clients via three gigabit Ethernet ports and one 10GbE SFP+ port. The robust Network Time Protocol (NTP) packet engine processes up to 50,000 requests per second to meet the most stringent demands of today’s networks.
These purpose-built network timing appliances have an embedded, streamlined, security-hardened operating system to ensure the integrity and reliability of the timing services. The internal proprietary GPS timing receiver has built-in protections and integrity checks to achieve best-in-industry accuracy. Anti-jam antennas are available to further enhance GPS signal reception by mitigating intentional and unintentional interference from ground sources.
“We are excited to launch the Sonoma D24 and N24 Network Time Servers to meet the timing requirements of next-generation networks and applications. These versatile four network port devices provide customers with many options to provide time synchronization services to air-gapped networks and isolated subnets.” said Michael Korreng, General Manager, EndRun Technologies. “The D24 and N24 carry forward the legendary EndRun reliability and performance that enterprise and mission critical applications depend upon.”
