Internet access in Cuba is severely constrained, due to limited availability, slow speeds, and high cost. Within this isolated environment, technology enthusiasts have constructed a disconnected but vibrant IP network that has grown organically to reach tens of thousands of households across Havana. We present the first detailed characterization of this deployment, which is known… Continue reading Initial Measurements of the Cuban Street Network

TapDance at Scale
I’m excited that the first project I helped on at Michigan will be presented at FOCI next month: An ISP-Scale Deployment of TapDance
IETF 98
Last week I talked briefly about the state of open internet measurement for network anomalies at IETF 98. This was my first time attending an IETF in-person meeting, and it was very useful in getting a better understanding of how to navigate the standards process, how it’s used by others, and what value can be… Continue reading IETF 98
Another Strike against Domain Fronting
In 2014, Domain Fronting became the newest obfuscation technique for covert, difficult to censor communication. Even today, the Meek Pluggable transport serves ~400GB of Tor traffic each day, at a cost of ~$3000/month. The basic technique is to make an HTTPS connection to the CDN directly, and then once the encryption has begun, make the… Continue reading Another Strike against Domain Fronting
Thoughts on IPv6 Measurement
About five years ago two projects, Zmap and Masscan, helped to shift the way that many researchers thought about the Internet. The tools both provide a relatively optimized code path for sending packets and collecting replies, and allow a researcher with moderate resources to attempt connections to every computer on the IPv4 Internet in about… Continue reading Thoughts on IPv6 Measurement

Internet Censorship 2016
We have reached the end of 2016, as well as the annual CCC congress in Germany. I had the exciting chance to speak together with Philipp Winter on the shifting landscape of Internet censorship in 2016. The talk followed mostly the same format as last year’s, calling out the continuing normalization and ubiquity of censorship… Continue reading Internet Censorship 2016
Thoughts on China’s Updated Cyber-security Regulations
On Monday, China ratified an updated cybersecurity legislation that will enter effect next June. The policy regulates a number of aspects of the Chinese Internet: What data companies need to keep on domestic servers, the interaction between companies and the government, and the interaction between companies and Chinese users. Notably, when considering the impact on… Continue reading Thoughts on China’s Updated Cyber-security Regulations
Excited to see Satellite chosen as best student paper this year at USENIX ATC. Slides and audio from the talk should be online shortly.
The CS department, as always, is on top of its news releases.
Graduation
I was fortunate enough to graduate from the University of Washington’s Computer Science and Engineering PhD program this spring. It has been an amazing five years, due in large part to an amazing group of colleagues.
