Quarterly Report

At the time of writing this report the access attempts reported by the system is over 15 million 1. We have noticed a decrease in filtered requests during this period.

In this quarter 22 appeals were received from users who were attempting to access a blocked. In all instances the appeals were processed by the review team and found to contain child abuse material thus the site remained on the list.

Below are examples of the text that was contained in some of the appeals

  • Curious
  • I want to look at this site.
  • This website is blookingch it. this & i wanna wat 

1 This number is not related to unique users or unique requests, rather the total amount of requests filtered during the particular period. For example 1 user could be responsible for a large number of filtered requests in 1 day and accessing a gallery page with links to multiple blocked sites will result in several filtered requests being recorded. Additionally this number also includes requests as a result of website pop-ups, pop-unders and spam content that a user may not be aware of.

System Maintenance

We are scheduling a series of system updates for the filter that will affect all systems. The updates are related to standard system maintenance needs such as firmware updates.

System Health

The system is currently filtering 2.5 million ISP clients, based on numbers supplied to the unit from the providers connected. At present we are using approximately 1% of the resources being the filter system itself and processing 1GB+ of traffic per day.

System Updates

During this period we were successful in connecting an additional provider to the system. We are now going to begin talks with the next scheduled provider.

Planned Information Updates

There have been no updates to the system information during this period
