Precision Time Infrastructure

Public Stratum 1 & 2 Network Time Protocol (NTP) and Network Time Security (NTS) infrastructure located across our two Bournemouth, UK facilities. Anchored directly by hardware GNSS/PPS reference clocks and backed by redundant cluster nodes for high-precision, cryptographically secure time synchronization.

Connection & Endpoints

Available globally over native IPv4 and IPv6 across clustered nodes in Bournemouth.

NTP Pool
ntp.vdx.sh
NTS Endpoint (Node 1)
nts.vdx.sh
Node 2 (NTP Only)
time2.vdx.sh

Client Configuration

Add the server directives below to your time daemon (Chrony, NTPsec, or modern ntpd):

Standard NTP Pool (`ntp.vdx.sh`)
server ntp.vdx.sh iburst
Secure NTS (`nts.vdx.sh`)
server nts.vdx.sh iburst nts
Standard NTP (`time2.vdx.sh`)
