We are committed to monitoring global NTP services and screening stable NTP services.
Multi service
Internet basic services are widely used and have a great impact. We will select nodes with an availability rate greater than 95% to join the domain name resolution of this site to minimize single point of failure.
Instant query
Provide instant query of various network time service ports (tcp13, udp13, tcp37, udp37, udp123) and common ports (tcp80, tcp443).
Continuous monitoring
The detection time of the network time service added to the long-term monitoring is 10 minutes / time to solve the situation that some nodes are not available due to attacks or other reasons.
