Apparently the hacker group anonymous is going to ddos the dia website in protest of the internet filter on March 29, at 11am but the news reports are suggesting they may have struck early:

Now what would happen if hypothetically the actual internet filter ip address was ddos? Would all the internet customers of isps who use the filter have their internet connections not work if the internet filter ip address is down?

TVNZ say the isps that currently use the filter are Airnet, Maxnet, Telecom, Telstra Clear, Watchdog and Xtreme Networks, so why don't these isps make the filter optional to customers so customers would have to opt into the filter or is the dia filter setup in a way that makes it impossible for some customers have to the filter and some customers to not have it?

Just imagine if anonymous does ddos the websites on March 29 and if they officially state they did, I think Telecom and others would lose alot of customers because the story will probably be reported worldwide. Maybe the geekzone admin needs to make a form where users can type their name and click send and a message would then be sent to all the isps that currently use the filter to remove the filter or make it entirely opt in.
