It is hard to judge the merits of this “study” or “report”. I
could find no report on the M-Lab site, the Free Press site, or
the BattleForTheNet site. Everyone just linked to or tweeted a
link to the Guardian article. When I emailed the writer asking for
a pointer to the report so I could examine the technical
methodology, data, and conclusions, I was told there was just a
private Google Docs document. That doesn’t seem quite right — it
makes it hard for engineers and researchers to independently
assess this.
But assuming a report is shared at some point in the future, if
the data relies on tests that end users initiate, which it may, it
is worth noting that such a measurement methodology was rejected
by the FCC in their Measuring Broadband America report in favor of
a system where the end measurement points are all homogenous.
Apart from removing significant self-selection bias, it means the
measurement is of the access network and not influenced by stuff
like WiFi (2.4GHz vs 5GHz, distance from AP, etc.) and what other
users on the LAN may be doing with the Internet connection (like
using up 50% of the capacity doing a download which would render
speed measurements invalid).

Major internet providers slowing traffic speeds for thousands

Major internet providers, including AT&T, Time Warner and
Verizon, are slowing data from popular websites to thousands
of
US businesses and residential customers in dozens of cities
across the country, according to a study released on Monday.
The
study, conducted by internet activists BattlefortheNet, looked
at
the results from 300,000 internet users and found significant
degradations on the networks of the five largest internet
service
providers (ISPs), representing 75% of all wireline households
across the US.
