More than 8,000 users from locations around the world have used our tool, Glasnost, to test whether their BitTorrent traffic is being manipulated. On this page, we present preliminary results from these tests. The tests were conducted between March 18th and May 15th 2008.
The only locations where cable ISPs blocked BitTorrent traffic to a significant extent were in the United States (Comcast and Cox) and Singapore (Starhub).
The table below shows the details of BitTorrent blocking for Comcast, Cox, and StarHub. For each ISP, we show (a) the number of distinct hosts we measured, and (b) the number of these hosts for which we detected BitTorrent blocking.
| ISP | Country | # measured hosts |
# blocked hosts |
|---|---|---|---|
| Comcast | USA | 788 | 491 |
| Cox | USA | 151 | 82 |
| StarHub | Singapore | 45 | 26 |
