Ping

Run a ping test from many locations and see four round-trip times for each one, including any location that could not start.

This check runs from servers in many countries. The address you enter is used only for this check and is not stored.

This check runs from servers in many countries. The address you enter is used only for this check and is not stored.

How to use Ping

  1. Enter a host name or an IP address.
  2. Tick the robot check and press Check.
  3. Read the summary, then each location. A full row is 4/4 with four times. A location that never probes shows its error on that row.

How it works

This check runs from servers in many countries. The address is used for that check and is not stored.

Each location sends four packets. The time is shown in milliseconds. The first answer can include the address that replied. Later answers are the status and the time. A status other than OK counts as a lost packet and keeps its label, such as TIMEOUT.

The same destination is sent out once a minute. Another request in that minute, including one from a second tab, shows the same result. A location that has not finished within 20 seconds stays on the list as "Still running".

Examples

  • A location that received every packet shows 4/4 and four times, such as 1.6, 0.8, 0.9, 0.8.
  • A location that could not begin shows Connect timeout, with no packet times.
  • Checking the same host again inside a minute shows the times from the check already made.

Limitations

  • The list of locations is whoever is up for that request. The next check can have a different set of cities.
  • A host that drops ICMP can show lost packets, or Connect timeout, while the website on port 443 still answers.
  • Private and reserved addresses are refused.
  • The packet count is four. There is no setting for size or for a longer run.

Frequently asked questions

Is this the same as opening the site in a browser?

No. Ping does not speak HTTP. A host can answer on port 443 and still ignore these packets.

Why is one city missing?

That location was not in the set that ran, or it did not finish and the row says "Still running".

Do you keep a history of the host?

No. A repeat inside one minute can reuse the result still held for that address. After that minute the result is gone.
