I just saw this post decided to a speed test at
www.speedtest.net and now getting a 25% speed increase. I have always complained about Bigpond slow speeds and when I called IINET to consider a change I found that the new regulated wholesale, retail split in Telstra has created a whole new set of boundaries. I previously wanted to change to IINET and was advised that my connectivity would still go through Telstra rubbish infrastructure. Now that has changed and can now achieve better consistancy through any provider as now the internet is carried directly to the ISP at the exchange. This is a great bonus as I can get some of the benifets of freezone options etc.
I believe that Telstra is now gonna have to pick up their games to become competitive and this maybe the new solution by not speed limiting.
I found out at least in my situation Telstra speed capped ADSL1 connection on a RIM. It seems from my test the speed cap is removed and so it seems.
