The pro-net neutrality coalition
Battle for the Net launched the test in May, and it has already produced an unprecedented amount of data: 2.5 million data points generated by more than 300,000 Internet users. This data trove gives researchers and the public valuable insight into whether broadband providers are complying with net neutrality rules.
Researchers from
Measurement Lab analyzed this rich dataset and announced their
initial findings last week. What they found should raise eyebrows: customers of AT&T, CenturyLink, Comcast, Time Warner Cable, and Verizon — the nation’s five largest ISPs — experienced significantly degraded Internet performance during the first half of 2015. In effect, millions of Americans aren’t getting the broadband service they paid for.
A key problem appears to be the gateways into the Internet’s so-called “last mile” — the networks that ISPs operate to reach their customers. These gateways, commonly referred to as interconnections, are how most online content reaches Internet users. Despite the importance of this critical component of the Internet’s architecture, there are few publicly available tools that measure interconnection activity. In such an opaque environment, anti-consumer behavior can occur without detection.
The Internet Health Test found evidence of significant congestion at interconnection points across the country. While congestion was observed on all of the nation’s five biggest ISPs, AT&T was the worst performer.
