Nope, all the tweets have come after the sites were already down.

Typical Anonymous/Lulzsec DDoS operations doesn't work like that, they need thousands of participants before it'll have any effect. If it was a public DDoS like the operations that took down DoJ about a year ago you would expect to see thousands of tweets about it and a lot of IRC activity.

It's also known that Anonymous can either use their own botnets or purchase access to botnets by the hour to conduct DDoS.

> So what is Multiboot.me? Well it’s a Pay-Per-Minute DDoS system that has been used by Anons (and others) to down US and other sites since LOIC got rumbled and DHN got pwned.

In addition, not all DDoS involve LOIC style attacks. It can use other types of exploits.
