TweakTown not accessible through Telstra Network

The largest tel co in Australia, also one of the biggest Internet providers in Australia, people using Telstra Internet services and the network as a whole cannot access TweakTown - This includes my school which uses a Telstra ISDN line, Telstra cable users, Telstra ADSL users and so on. I'm not sure why this problem is, but I've got some feedback on this issue - Loyal readers have even been swapping ISP's so they can access TweakTown as per usual. I will be contacting Telstra shortly so we can try and resolve this problem together. If people are changing ISP's, I think it is a big enough problem for Telstra to take responsibility and take the required action to fix the problem.
