How do I test the network speed to my dedicated server?

Our looking glass lets you check the network without taking our word for it. Download a file, watch the number, argue with it.

Steps

Know which location your server is in: Las Vegas or Seattle. Your standard port is 1000Mbps, so about 1 gigabit per second is the ceiling, and your own connection is probably the limit.

  1. Open the looking glass for your location:

  2. Use the test files on that site. They are 25 MB, 100 MB, and 1000 MB. Larger files give a steadier reading.
  3. To test from the server itself, run wget -O /dev/null http://lg.las1.as53340.net/100MB.test (use lg.sea1 for Seattle). The speed is shown at the end of the line.
  4. Run a traceroute or MTR from your server to the looking glass host and back. From your own computer, run mtr -rw -c 20 YOUR.MAIN.IP (Windows: tracert YOUR.MAIN.IP).
  5. Save the results. Run the test two or three times at different times of day.
  6. Compare with a test from a second network (for example, phone data). If the speed is fine there, the limit is likely your own connection.

If it didn't work

  • Slow only to one place, normal elsewhere? The path is likely at fault, so send us a traceroute rather than a ping. It shows where the trouble starts.
  • A single download stream may not fill a gigabit link. Try several at once.
  • Open a ticket in the portal, set Department to Technical Support, and include your Main IP, your location, the test results, and the traceroutes from both directions.
