Most M-Lab tests should take less than thirty seconds to complete, so if your particular test is taking longer, there may be something wrong. First, do the following:
- Try running the test again. Perhaps an unusual network issue caused the problem.
- Try running the test from a different location. For example, if it failed at your home, does the test work at a coffee shop?
- If the test doesn’t start or never completes, is your connection behind a firewall? This may be the case at some workplaces where the network is actively managed.
If none of the above solves the issue you are experiencing, you can report a bug by emailing support@measurementlab.net.
When reporting a bug, please provide (if at all possible) the following specific information:
- Your operating system
- Your browser name and version
- The name of the test that is not working
- Any error messages you have received
M-Lab support will usually reply within five business days. You can also ask other M-Lab users about the issue you are reporting in the M-Lab-Discuss group.
