There are numerous reports of traffic flow problems from aaNet's Melbourne PoP out through Optus.
This affects international and some National traffic.

One workaround for web broswing is to explicitly set your browser to use one of the Sydney or Brisbane proxies, listed here: viewtopic.php?p=209074#p209074

Network support have been notified.

Update: it is apparently another DDOS.
Eftel network support expect to have it under control shortly - maybe 30 minutes.

Jason posted the following comments on Whirlpool:

A small number of IP ranges were blocked, as there was a long, and ongoing denial of service attack directed to a few customers in those ranges.

In order to prevent a lack of internet access for tens of thousands of people the above action was taken. Staff continued to test during the entire duration to ensure we could bring up those routes as quickly once the issue subsided.

...
Detail of the issue was posted on our Outage Notifications page on the EFTel site, as well as a post from a Moderator on the aaNet forums. Could those systems/processes be improved? You bet ya – that is one of the main projects I am working on.

In relation to preventing it happening again, you need to understand exactly what a DDoS is(try wikipedia), to know that it is impossible to prevent it ever happening in the future.

When you have hundreds or thousands of mbits of junk data being directed at a handful of users, or even just a single user in one state, there is little that can be done.
