An International Conspiracy to Make the World Safe for ECN

Update: June 13, 2016

We rerun ECN Spider from one vantage point on a virtual machine from hosting provider Digital Oceans in Netherlands on June 13, 2016 and can report another increase in ECN support on web servers of the Alexa 1 million list (as of June 12, 2016). High level stats are here (more data to follow):

432544 of  617873 (70.005%) of IPv4 addresses negotiate ECN
20262 of  24472 (82.797%) of IPv6 addresses negotiate ECN
452806 of  642345 (70.493%) of all addresses negotiate ECN
2809 of  628896 (0.447%) of IPv4 addresses may have ECN dependency
30 of  26393 (0.114%) of IPv6 addresses may have ECN dependency
2839 of  655289 (0.433%) of all addresses may have ECN dependency


ECN-connection dependency by rank of Alexa list (TCP without ECN connected but TCP with ECN did not):


ECN support by rank of Alexa list (ECN was successfully negoatiated):

Overview

This webpage provides measurement data on ECN deployment. Therefore we've run ECN Spider at three vantage points, on virtual machines running Ubuntu 14.04 (kernel 3.13.0) run by commercial hosting provider Digital Ocean at datacenters in London, New York, and Singapore.

Name resolution based on the Alexa 1 million list was performed on 27 August 2014 from the London vantage point using Google's public DNS server (8.8.8.8), resulting in 581,737 unique IPv4 addresses and 17,029 unique IPv6 addresses.
