Connection quality is more than speed and ping
Most speed tests report throughput in Mbps. That matters, but it does not show whether calls, games, browsing, and streaming stay responsive while the connection is already carrying traffic.
Free and open source. Public methodology. Inspectable results.
The real-life test for your internet connection
Speed tests can say everything is fine while games lag, pages stall, and video calls drop in real life.
Bufferbloat.org measures the hidden delay that appears when data queues behind real download and upload traffic. The result shows whether your connection stays usable in real life, not just how many megabits it can move in ideal conditions.

Test the line while it is under pressure
The test samples quiet-line ping, then repeats the measurement while download and upload traffic are active. The important signal is how much responsiveness changes when the line is busy.
A public-interest test, not a black box
Measuring connection quality should be free, transparent, and accessible. Source code, methodology, and limitations are public so results can be checked, debated, and improved.
public-interest resource
Open methodology, inspectable implementation.
Bufferbloat.org exists because this kind of measurement should exist. Internet connection quality is too important to be left to opaque and gimmicky speed tests. The public test is free, open source, and will never be supported by advertising. If the project needs funding to operate at scale, funding must not compromise the methodology, results, or user privacy.
