AT&T Unblocks /b/

AT&T has unblocked /b/ claiming the initial block was due to a suspected DDoS attack coming from a 4chan.org IP address.

 

Beginning Friday, an AT&T customer was impacted by a denial-of-service attack stemming from IP addresses connected to img.4chan.org. To prevent this attack from disrupting service for the impacted AT&T customer, and to prevent the attack from spreading to impact our other customers, AT&T temporarily blocked access to the IP addresses in question for our customers. This action was in no way related to the content at img.4chan.org; our focus was on protecting our customers from malicious traffic.

Overnight Sunday, after we determined the denial-of-service threat no longer existed, AT&T removed the block on the IP addresses in question. We will continue to monitor for denial-of-service activity and any malicious traffic to protect our customers.

Time will tell if this is true or not, but it seems unlikely that that 4chan.org was the source of a DDoS…in fact, by definition, a single IP CANT be a DDoS, either way, the ban is lifted and it was smart of AT&T to do so.
