Backend RSP Systemic Risk Radar
Infrastructure IntelligenceWhile thousands of front-end registry entities exist, the global DNS relies on a small handful of technical Registry Service Providers (RSPs). This radar audits backend infrastructure concentration, Anycast BGP network resilience, and single-point-of-failure vulnerabilities across top technical registry operators.

Backend RSP Risk FAQ
Audited FAQ ReferenceQ1. What is a Registry Service Provider (RSP) in the domain system?
A Registry Service Provider (RSP) is the specialized technical contractor responsible for running the mission-critical registry infrastructure of a TLD. This includes operating the EPP shared registration system, maintaining the SRS database, generating and signing the zone file with DNSSEC, and distributing the zone across global Anycast nameserver networks.
Q2. Why does backend RSP concentration represent a systemic DNS risk?
A high concentration of global domains on a handful of RSPs creates single points of failure. If an RSP experiences routing anomalies, Anycast BGP hijacking, catastrophic hardware failures, or software bugs during zone generation, hundreds of diverse TLDs can simultaneously suffer resolution failures.
Q3. Can a registry operator switch technical backend providers?
Yes. Registry operators can migrate between RSPs, though it requires coordinated transition planning approved by ICANN to migrate EPP credentials, historical billing records, registrant data, and DNSSEC keys without causing downtime for live internet domains.
Q4. How do ICANN RSP evaluation standards work for the Next Round?
Under the ICANN Next Round rules, Registry Service Providers undergo a standardized pre-evaluation program to certify their technical capacity, IPv6 readiness, DNSSEC compliance, SLA performance, and Anycast redundancy before supporting new gTLD applicants.
