The site most often blamed for launching protest DDOS attacks against religious and commercial sites on the Internet was, itself, under attack yesterday.
"Site is down due to DDoS," the sysadmin Moot posted on 4Chan's status page at 2:39 a.m. Tuesday. " We now join the ranks of MasterCard, Visa, PayPal, et al.—an exclusive club!"
Only parts of the site -- which is made up primarily of discrete discussion boards and associated IRC channels -- were down. Most discussion boards remained up for most of the attack, though the ability to post new files, search and post some new discussions and files were down.
By this morning most of the discussion boards were responding quickly, as were back-channel discussion boards on which 4Chan members -- almost all of whom carry the username "Anonymous" -- discussed the attack and potential responses.
4Chan -- considered a focal point of porn, hactivism and chaos -- is the source from which the hactivist group calling itself "Anonymous" was launched with an attack on the Church of Scientology three years ago.
There is no indication so far of who was behind the attack.
