IP anycast routes packets to the topologically nearest#N#server according to BGP proximity. In the last years, new players#N#have started adopting this technology to serve web content via#N#Anycast-enabled CDNs (A-CDN). To the best of our knowledge,#N#in the literature, there are studies that focus on a specific A-CDN#N#deployment, but little is known about the users and the services#N#that A-CDNs are serving in the Internet at large.#N#This prompted us to perform a passive characterization study,#N#bringing out the principal A-CDN actors in our monitored setup,#N#the services they offer, their penetration, etc. Results show a#N#very heterogeneous picture, with A-CDN empowered services#N#that are very popular (e.g., Twitter or Bing), serve a lot of#N#different contents (e.g., Wordpress or adult content), and even#N#include audio/video streaming (e.g., Soundcloud, or Vine). Our#N#measurements show that the A-CDN technology is quite mature#N#and popular, with more than 50% of web users that access#N#content served by a A-CDN during peak time
