a Mystery DDoS attack you say
So the ABS is claiming some mystery DDOS attack, yet there seems to be no evidence of that at all
If you look www.digitalattackmap.com for last night there was no recorded DDOS attacks in this country.
Also if you are paying $10M for a cloud service
a) I would hope the SLA the ABS should have with IBM would mean they can get a fair amount of compo
b) That someone would have thought about a DDOS and designed the system to cope with is.
Update: I see in the press conference that they had, they are now blaming an overloaded switch.
so they obviously have never heard of redundancy, or distributed infrastructure
