Abstract
Anycast is a replication technique where a single IP address is made available at multiple geographic locations.
Users connecting to such a replicated service are routed to the best replica using BGP.
This replication allows for bringing services closer to users, and provides resilience by automatically redirecting users when one replica becomes unavailable.
Due to these benefits, anycast is widely used for critical Internet infrastructure like the DNS (e.g., used by all root-letter operators).
However, anycast deployments often lack coverage in formerly colonized nations in Africa and central America.
As a result, the resilience of anycast is lessened for users in these regions.
Problems such as colonial routing further complicate this issue as, for example, former French colonies may prefer a long route to a replica in Paris instead of nearby replicas in former British colonies.
This talk will shed light on these problems and shares preliminary results of our measurements on anycast connectivity in such regions.
Our goal is to reach operators that are willing to help us deploy in these regions to further measure this problem and assess the improvements possible when operators deploy in these regions.

Remi Hendriks is a third-year PhD student in the DACS group
at the University of Twente, Netherlands. His research focuses on anycast as a tool to both
measure and improve Internet resiliency.
His work includes LACeS, an open, fast, and responsible longitudinal anycast
census system published at IMC 2025, developed with support from the RIPE NCC Community Project Fund.
Remi is especially interested in deploying anycast in underserved regions and welcomes collaboration on this topic.
