Condobolin sends in an update to the Australian government's ongoing efforts to implement ISP-level filtering. One of the hurdles they had to overcome was to build a system that would allow them to filter content without impairing other internet usage. A trial of the system has just concluded, and the results are positive — at least, for the government. Quoting: "More than half of the Internet service providers (ISPs) taking part in the Federal Government's ISP filtering trial have reported minimal speed disruptions or technology problems. Of the nine participating ISPs, iPrimus, Netforce, Webshield, Nelson Bay Online and OMNIconnect told ARN they had seen no slowdowns in Internet speeds or problems with the filtering solutions in place. Of the remaining four ISPs, Tech2U and Highway1 were unable to respond by time of publication while Unwired and Optus refused to comment. ... 'From a technical perspective we're more than confident that if the government decided to roll out a mandatory Internet filter based on or around an Australian Communications and Media Authority blacklist or subset thereof, then it can be done without any impact whatsoever to the speed of the Internet,' [said Webshield managing director Anthony Pillion]."
