Yes, the number of users is one thing, but they didn't prepare for
the amount of concurrent users, millions of people hitting the site
at once. <br>
It isn't just the server you need to worry about, you need a
redundant network and they only seamed to have a small number of
providers. <br>
But they also only had a couple of Datacentres as well. <br>
IBM own Softlayer who have multiple DCs hear in Australia, which for
a project like this the federal government / ABS should of taken
full advantage of. <br>
But trying to get everyone to fill out the form online all at the
same time, was a bad idea in the first place, as planning for such
large scale events is quite difficult. <br>
Realistically the bandwidth costs would be rather high as well. <br>
If they had used the entire AU capacity of the Australian Softlayer
network then they might of been able to pull it off, but the more
load balancers and other complexities that you add in the more stuff
their is to fail. <br>
They would of had to of spent more money on load testing and the
like. <br>
At least they were using VMware. <br>
But they should of promoted that people had longer to do it, instead
of doing that they created a PR disaster. <br>
