AT&T Lifts 4Chan Block, Was To Stop DDos Attacks

AT&T released a statement about their temporary blocking this weekend of troll haven 4chan for its customers. The company said the temporary block was to stop DDos attacks on one customer emanating from IP addresses associated with the site. After the threat was over, the block was lifted. Here’s the official release:

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.
