Functional and Performance Specifications
Pursuant to the responsibility delegated to it in Appendix S, Registry Operator will prescribe functional requirements for Registry Services provided for the Sponsored TLD which shall ensure that at least the following minimum functional capabilities are provided.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in IETF RFC 2119.
2. Nameserver Requirements
The nameservers for the Sponsored TLD MUST be operated in compliance with the following Requests for Comments (RFCs): 1034, 1035, 1101, 2181, 2182. In clarification of the statement of host-name rules in these RFCs, all Registered Names SHALL comply with the following syntax in augmented Backus-Naur Form (BNF) as described in RFC 2234:
dot = %x2E ; "."
There MUST be nameservers for the Sponsored TLD on at least five different network segments. So that the IANA has zone-file access, zone-file transfers MUST be enabled at all nameservers for transfers to at least 184.108.40.206/16 and 220.127.116.11/20.
3. Registry System Requirements
The registry system MUST enforce the name reservations and Charter requirements set forth in Appendix S.
4. Whois Service Requirements
Whois service MUST meet at least the functional specifications set forth in Appendix 5.
5. Data Escrow Requirements
Data escrow MUST meet at least the functional specifications set forth in Appendix 1. The registry shall be capable of storing the data to be escrowed.
6. Reporting Requirements
The registry system MUST provide data sufficient to meet the reporting requirements set forth in Appendix 4.
7. Performance Specifications
DNS Service Availability. Service availability as it applies to the DNS Service refers to the ability of the Nameservers, as a group, to resolve a DNS query from an Internet user. The committed Performance Specification is 99.999% measured in Monthly Timeframes.
Performance Level. At any time at which it is available, each Nameserver (including a cluster of Nameservers addressed at a shared IP address) MUST be able to handle a load of queries for DNS data that is three times the measured daily peak (averaged over the Monthly Timeframe) of such requests on the most loaded Nameserver.
Cross-Network Nameserver Performance Requirements. The committed Performance Specification for cross-network Nameserver performance is a measured Round-trip time of under 300 ms and measured packet loss of under 10%. Cross-network Nameserver performance measurements will be conducted by ICANN at times of its choosing, in the following manner:
The measurements will be conducted by sending strings of DNS request packets from each of four measuring locations to each of the Nameservers and observing the responses from the Nameservers. (These strings of requests and responses are referred to as a "CNNP Test".) The measuring locations will be four root nameserver locations (on the US East Coast, US West Coast, Asia, and Europe).
Each string of request packets will consist of 100 UDP packets at 10-second intervals requesting ns records for arbitrarily selected second-level domains in the Sponsored TLD, preselected to ensure that the names exist in the Sponsored TLD and are resolvable. The packet loss (i.e. the percentage of response packets not received) and the average Round-trip time for response packets received will be noted.
To meet the packet loss and Round-trip-time requirements for a particular CNNP Test, all three of the following must be true:
The Round-trip time and packet loss from each measurement location to at least one Nameserver must not exceed the required values.
The Round-trip time to each of 75% of the Nameservers from at least one of the measurement locations must not exceed the required value.
The packet loss to each of the Nameservers from at least one of the measurement locations must not exceed the required value.
Any failing CNNP Test result obtained during an identified Core Internet Service Failure shall not be considered.
To ensure a properly diverse testing sample, ICANN will conduct the CNNP Tests at varying times (i.e. at different times of day, as well as on different days of the week). The cross-network Nameserver performance requirement will be deemed to have not been met only if the Nameservers persistently fail the CNNP Tests with no less than three consecutive failed CNNP Tests to be considered to have persistently failed.
In the event of persistent failure of the CNNP Tests, ICANN will give Registry Operator written notice of the failures (with backup data) and Registry Operator will have sixty days to cure the failure.
If, following Registry Operator's opportunity to cure, the Nameservers continue to persistently fail CNNP Tests and Registry Operator fails to resolve the problem within thirty days after written notice of the continuing failures, Registry Operator will be in breach of its obligations under the Registry Agreement.
Sixty days before the commencement of testing under this provision, ICANN will provide Registry Operator with the opportunity to evaluate the testing tools and procedures to be used by ICANN. In the event that Registry Operator does not approve of such tools and procedures, ICANN will work directly with Registry Operator to make necessary modifications.
Whois Service Availability. The committed Performance Specification for Whois Service is 99.4% measured in Monthly Timeframes.
Whois Service Performance Level. The Whois Service will, on average, be able to handle 50 queries per second.
Whois Service Response Times. The Whois Service will have a worst-case response time of 1.5 seconds, not including network delays, before it will be considered unavailable.
Whois Service Updates. The data provided by the Whois Service will be updated on at least a daily basis.
8. Wide Location of Data Centers
Data centers for registration services will be provided by the back-end provider, currently VeriSign, and will exhibit a wide location of data centers. The primary data center is located in Virginia, USA. The dependent, C2 center is located in the United Kingdom. A disaster recovery data center is also located in Virginia, USA, but on a different power grid than the primary data center.
9. Fail Over Practice
Fail over from one data center to another will be practiced at least once every two years as part of the registry’s robust disaster recovery plan. Any such fail over practice will be planned in advance, and the registrars will be given advance notification.
Registry Operator will be deploying EPP v.1.0 for communications with the registry.
