Oh, that is only because Iran invaded Iraq today.
(Only half kidding, they actually
did as it seems)
Edit:
Also, as I now got around to reading the BBC bit, I think it is time that
DNSSec is implemented on a wide scale. Although the article from the BBC is not really specific, it doesn't really get clear, if they hacked a Twitter owned DNS server or a server up the hierarchy.
For those of you, who think twitters programmers must be bad, because they get hacked all the time, that is only half true. Twitter is now among one of the most popular services and therefore a high profile target, so it is no wonder it gets hacked more often than other sites.
