I’m excited to present Satellite, a network measurement project I’ve been working on over the last couple years, at USENIX ATC next month.

Satellite takes a look at understanding shared CDN behaviors and automatically detecting censorship by regularly querying open DNS resolvers around the world.

For example, we can watch the trends in censorship in Iran using only a single, external machine.

The data for satellite is posted publicly each week, and will shortly be merged into the OONI data set to help provide better baselines for what behavior should be occurring.

The state of Internet Censorship

I’ll be presenting next week at 32C3 on the state of Internet access, transparency, and measurement. Lots of the work is done each year on measuring and learning about the state of access, but this phenomenon with growing relevance to many countries is poorly publicized. Much of this is a fear that being too public about what can be measured will make the network operators move to even more opaque techniques, since in many instances these systems are seen to thrive in structures without accountability.

Needless to say, it has been a busy year in the space, with increased funding for the measurement community and a multitude of new policy in response to ISIS and other perceived threatening uses of Internet Speech.

I’m excited to be heading back to Germany for the holidays, and hope to provide a reasonable survey of what’s out there and make the network measurement field a bit more accessible!

3rd International conference of PUST


I returned to PUST this fall just in time for ICOPUST3, a bi-annual conference hosted by the university and one of the few instances of international academic engagement performed by the university.

A bit of background: I spoke on my research at ICOPUST2, the previous instance of this conference held two years ago, and my first time visiting the university. The conference by design is a multi-track affair covering the full breadth of academics (from computer science to agriculture) taught at the university.

This year, I acted as the session chair for the computer science track of the conference, which proved to be quite rewarding. I’m encouraged by the continued academic engagement present at the conference and occurring at the university as a whole.

Open Tech Fund

I’m excited to be supported by the Open Technology Fund on my research of activist.js. I’ve found myself in highly esteemed company, and hope to live up to goals of program.

Will Scott, a graduate student in the Networking Lab at the University of Washington, will continue his work on Activist.js, a tool that helps publishers resist censorship by maintaining strong websites that are more resilient to network interference.
