AT&T's 4chan Block Raises Issue of Network Neutrality

It appears some of AT&T's broadband customers across the United States were intentionally blocked from accessing the infamous forum 4chan over the weekend. The message board's founder Christopher "Moot" Poole encouraged 4chan users to contact AT&T to complain. The 4chan black out lasted for about 12 hours. AT&T claims it did so because of a denial of service attack originating from IP addresses connected to a 4chan server. unWired, also had to temporarily block 4chan because of what unWired described to Broadband Reports as "relentless ACK scan reports." Even if it turns out the ISPs' decisions were legitimate, the appearance of censorship raises the contentious issue of network neutrality -- the belief that ISPs should not be allowed to block or slow down traffic to any Website.
