"Until now, there hasn't been a reliable way to tell if somebody, a hacker, an ISP, corporate firewall, or the Great Firewall of China, is modifying your Internet traffic en route," explained Peter Eckersley, the EFF Staff Technologist who designed the tool.
"Switzerland is designed to make general-purpose ISP testing faster and easier."
The tool follows the recent decision by the FCC that ISPs in the United States cannot "purposely" restrict any type of traffic. The US' largest ISP, Comcast was at the center of the debate when it was found to be throttling/limiting BitTorrent traffic.
Despite the recent decision however, the EFF believes the FCC is "ill-equipped" to stop ISPs from disregarding net neutrality laws.
"The sad truth is that the FCC is ill-equipped to detect ISPs interfering with your Internet connection," said Fred von Lohmann, the group's senior intellectual property attorney.
"It's up to concerned Internet users to investigate possible network neutrality violations, and EFF's Switzerland software is designed to help with that effort. Comcast isn't the first, and certainly won't be the last, ISP to meddle surreptitiously with its subscribers' Internet communications for its own benefit."
