There are hundreds of different speed tests you can find of the internet if you search. I have set up one that looks to be very accurate and offers a number of geographic sites to test from. It is managed by ookla.com. Ookla is the global leader in internet testing, data, and analysis. Speedtest, the company’s flagship product, is the most accurate way to measure internet performance and network diagnostics.
Use this one first http://digitalphone.speedtestcustom.com/ when testing. You can then copy the results and send the unique URL with the test to others that might be trying to help you diagnose your speed, jitter, or latency problems.
