USC/ISI’s root DNS server (b.root-servers.net) is in the process of moving from Amsterdam to Frankfurt. We stopped anycast service in Amsterdam on 2025-06-02, and we expect service to start at Frankfurt in late June 2025.
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.
