Data Catalog
Open Internet measurement data released under CC0 — freely available for research, policy, and public interest analysis.
M-Lab data is published in two forms: enriched data (parsed, annotated, and queryable via BigQuery or available as pre-computed summaries) and archival data (measurement logs on Google Cloud Storage for deeper analysis). Both are released under CC0 1.0 Universal with no restrictions on use.
Enriched Datasets
Start here. These datasets have been parsed, annotated, and structured for analysis — queryable via BigQuery or downloadable as pre-computed summaries. Most research questions can be answered without touching raw data.
Raw Datasets
Unprocessed measurement logs and archives as collected directly from M-Lab's infrastructure, stored in Google Cloud Storage. Use these when enriched datasets don't cover your specific analysis need.
NDT (Network Diagnostic Tool) Dataset
The NDT dataset contains measurements of TCP throughput and latency collected by the Network Diagnostic Tool (NDT). NDT is a single-stream performance measurement of a connection's capacity for bulk transport. Measurements include download speed, upload speed, round-trip time (RTT), and packet loss between end-user devices and M-Lab servers worldwide.

Wehe Dataset
The Wehe dataset contains measurements collected by the Wehe app, which detects traffic differentiation (throttling) by ISPs for specific application types such as video streaming, music streaming, and conferencing. Each test replays recorded traffic from popular applications and compares the throughput achieved using original versus anonymized traffic.
