Frequently Asked Questions

What does a ping test measure?
It measures whether a host is reachable and the round-trip time of packets (latency); lower latency means faster response.
If ping fails, is the site down?
Not necessarily; some servers deliberately ignore ping (ICMP) while their web service is up. Use the HTTP Test or Port Check to be sure.
