Persistent Last-mile Congestion: Not so Uncommon


Survey results

The survey results shown on this website are available in JSON format:

Traceroute data

Raw traceroute data is available through the RIPE Atlas API:

For this study we used data from the following measurement ID: 5009, 5010, 5011, 5012, 5013, 5004, 5014, 5015, 5005, 5016, 5001, 5008, 5006, 5030, 5031, 5029, 5028, 5017, 5019, 5027, 5051, 5151

RTT time-series

The last-mile median RTT time-series for each Atlas probe are available in two formats.

Sqlite snapshots

The results for the 7 measurement periods presented in the IMC paper are available as sqlite databases. Note that a last processing step is required to obtain the median last-mile queuing delay (see source code page).

Internet Health Report (IHR) API

We also provide near real time last-mile median RTT on the IHR API: Data is available from January 2020. Here is an example to get last-mile median RTTs for all probes in AS7922 around March 1st at midnight: (LM47922 is not a typo LM4 stands for Last-Mile-IPv4)
