The Broadband Internet Speed Test (Gone) is first seen on the Wayback machine August 2005.
The Broadband Internet Speed Test is a Miscellaneous speed test. This is because, oddly enough, this speed test only works if Javascript is disabled.
With an advertised speed of 100 Mbps, the Broadband Internet Speed test measures 11933 kbps. That is 12 Mbps. This value is so different from the speed to be measured that this speed test is not recommended.
