USC/ISI’s root DNS server (b.root-servers.net) has finished moving from Amsterdam to Frankfurt. We stopped anycast service in Amsterdam on 2025-06-02, and we resumed service at Frankfurt on 2025-08-18.
This instance is kindly hosted by Go Daddy, and we thank them for their continued network and data-center support as they transition our infrastructure from one data center to another.
Please address any questions about B-Root operations to b-poc (at) isi.edu.
