Emergency Back-end Registry Operator
Note: The English language version of all content and documents in this section is the official version. Translations in other languages are for informational purposes only.
The establishment of Emergency Back-end Registry Operators, or EBEROs, are an important innovation of the New gTLD Program. An EBERO provider is temporarily activated if a generic Top-Level Domain (gTLD) operator is at risk of failing to sustain any of the five critical registry functions. Ensuring the availability of these functions protects registrants, also known as domain name holders, and provides an additional layer of protection to the Domain Name System (DNS), and industry ecosystem. These five critical registry functions are:
- DNS resolution for registered domain names
- Operation of Shared Registration System
- Operation of Registration Data Directory Services
- Registry data escrow deposits
- Maintenance of a properly signed zone in accordance with DNSSEC requirements
EBERO providers are limited in the services they can provide. For example, EBERO providers will not provide any additional services that a gTLD operator may have offered its customers, such as web hosting or network analytics.
The currently contracted organizations meet stringent technical requirements and have demonstrated years of experience in operating domain name services, registration data directory services and extensible provisioning protocol services. They are:
- Canadian Internet Registration Authority (CIRA)
- China Internet Network Information Center (CNNIC)
ICANN is responsible for declaring an event requiring EBERO emergency services and coordinating all emergency response activities. EBERO does not apply to some Legacy gTLDs.
