Why do some speedtest results appear greater than the cap?

There are 5 possible reasons why test speeds that greatly exceed the BellSouth DSL cap of 1472kbps downstream and 256kbps upstream may appear in the DSLReports Speed Test database: •They may be IFITL and not ADSL customers. Because IFITL uses traffic shaping and not a hard coded provisioning some IFITL customers may downstream speeds in the 1800 – 2000kbps range. •They may have been using an ISP proxy server. If that is the case, the speed test results are not accurate at all. When the speed test is run from a PC that is using an ISP proxy server, it is the speed between the test server and the proxy, not between the test server and the end user that is actually reported. Most proxy servers are on a very high speed backbone connection. •The speed was tested using some other high speed access line (work, friends cable modem, etc). Speeds are logged to the ISP listed in your DSLReports member profile by default.
