Anonymous is planning to bring down the internet. March 31.

You'd think somebody would've done it already.

Well...there are a few reasons someone wouldn't have done already...

1) This is going to need a fuckton of manpower. Getting this kind of recruitment is vastly different from having a few friends helping you. You'd have to go very public to get enough people or not even bother.

2) So you took down a DNS server. What then? This op is a protest, anything else would just be for lulz, nothing to be gained.

3) Maybe the IPs of the DNS servers weren't very well known aside from those who had an interest in hacking or networking, so only those determined enough would be able to figure them out.
