Service Level Agreement

Between InternetNZ and the registry, NZRSManaged for InternetNZ by the Office of the Domain Name Commissioner (DNC)SLA includes:

Register performance and management standardsAvailability and response timesReporting and communication requirementshttp://www.dnc.org.nz/content/SLA_10_April_2003.pdf

Availability requirements

SRS – 99.9%

WHOIS service – 99.9%

DNS – 100%

SRS and WHOIS

99.9% standard setExcludes planned outagesCalculated using system logs and incident logs associated with each system

% available = (Scheduled availability – Unscheduled outage time) / (Scheduled availability) * 100

SRS Performance

Monitor all Registrar SRS transactions response times at the SRS front-end servers

Measure the average response time for all valid SRS transactions

Monitor the public WHOIS service response times from a point outside the firewall

Measure the average WHOIS service transaction response time by periodic active WHOIS queries

SRS Response Times

Transaction Type Target Response Times

Domain Details Query ≤ 1.5 seconds

WHOIS ≤ 0.5 seconds

UDAI Validation ≤ 0.5 seconds

Domain Update ≤ 0.4 seconds

Domain Create ≤ 0.6 seconds

Get Messages ≤ 0.6 seconds

DNS standards

100% availabilityZone files required to be 100% accurate across all DNS servers within the agreed period after the scheduled zone pushZone push window currently 40 minutes

DNS response times

Figures derived from stress testing the name servers1201 UDP and 121 TCP transactions usedTarget for UDP < 5.0 millisecondsTarget for TCP < 50.0 milliseconds
