  6. SRS and WHOIS • 99.9% standard set • Excludes planned outages • Calculated using system logs and incident logs associated with each system • % available = (Scheduled availability – Unscheduled outage time) / (Scheduled availability) * 100

  7. 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

  9. DNS standards • 100% availability • Zone files required to be 100% accurate across all DNS servers within the agreed period after the scheduled zone push • Zone push window currently 40 minutes

  10. DNS response times • Figures derived from stress testing the name servers • 1201 UDP and 121 TCP transactions used • Target for UDP < 5.0 milliseconds • Target for TCP < 50.0 milliseconds
