RTT.ICU

About this tool

A free online ping test that measures round-trip latency, jitter, and packet loss to any hostname or IP from 240+ global probe locations.

  • Enter a hostname or IP address such as github.com or 1.1.1.1.
  • Choose a region or run from the default global probe set.
  • Run the ping and compare latency, jitter, and packet loss across regions.
Frequently asked questions
What is a good ping latency?
Under 30 ms feels instant for most tasks. Under 80 ms is comfortable for web browsing and video calls, while competitive gaming usually wants under 50 ms. Distance matters: intercontinental links add physics-bound delay.
Why do I see packet loss on some probes but not others?
Packet loss is often regional. A congested route between one probe and your target can drop packets while other regions stay clean. Comparing multiple regions separates a local routing problem from a problem at the destination.
Does this ping test use ICMP?
Yes. The remote probes send standard ICMP echo requests to the target, then report round-trip time and loss per packet, so results match what the ping command shows.
