To improve B-Root DNS service, B-Root will be activating anycast on 2017-05-01, providing service from a new site in Miami in addition to our current site in Los Angeles. We thank Florida International University (https://www.fiu.edu) and Ampath.net (https://ampath.net) for hosting our new hardware there, and USC (https://www.usc.edu) for hardware support for this second site. As part of this deployment, we will be renumbering B-Root's IPv6 address to 2001:500:200::b, effective on 2017-06-01. We also plan renumber our IPv4 address later in 2017; we will announce that date here. Renumbering will help support anycast with more resilient routing. (We will provide service on our old IPv6 and IPv4 addresses for at least one year after renumbering.)
