B-root’s new sites reduce latency

B-Root, one of the 13 root DNS servers, deployed three new sites in January 2020, doubling its footprint and adding its first sites in Asia and Europe. How did this growth lower latency to users? We looked at B-Root deployment with Verfploter to answer this question. The end result was that new sites in Asia and Europe allowed users there to resolve DNS names with B-Root with lower latency (see the catchment map below). For more details please review our anycast catchment page.

B-root added 3 new sites in Singapore, Washington, DC, and Amsterdam to their three existing 3 sites in Los Angeles, Chile, and Miami. The graph below shows anycast catchments after these sites were deployed (each color in the pie charts shows traffic to a different site).
