Update: Verizon Wireless says 4Chan source of malicous network attacks

Update: Verizon Wireless spokesman, Jeffrey Nelson, said two of 4Chan's related sites (not its main one) were sources of malicious attacks, which threatened the wireless network. He said the company didn't block the site but was addressing the security concerns. He said both sites should be accessible to users by the end of the day.

Here's his earlier tweet: "@JNels Some 4Chan web sites potentially disruptive of Verizon network now have green-light. We are monitoring network for harm"

Verizon pokesman James Gerace explained why the site was cut off the network in a blog post.

4Chan hasn't immediately responded to questions about Verizon's explanation about malicious attacks through its related sites.

The episode follows complaints by 4Chan last year that its sites were also blocked by AT&T.

And here's our original post:

Headline: 4Chan says being blocked by Verizon Wireless
4Chan, an online bulletin board popular among Japanese anime and gaming fans, said its site is being blocked by Verizon Wireless on mobile devices.

A Verizon Wireless spokesman said the firm was looking in to it and would get back to PostTech. We will update with any comments.

4Chan disclosed the alleged blocking on its Web site and on Twitter, where it said Sunday that the nation's largest wireless services provider confirmed it had blocked the site. Quickly, the company's tweet was "re-tweeted" and spread through Twitterverse over the weekend. 4Chan, started by a 15-year-old in New York who goes by the username "moot," is a popular hub to exchange images on Japanese anime and pop culture. According to its Web site, it gets about 7 million unique visitors each month.

If true, the move would violate guidelines by the Federal Communications Commission that prohibit Internet service providers such as Verizon, AT&T and Comcast from shutting down Web sites for their subscribers. FCC Chairman Julius Genachowski is crafting controversial regulations that would make those principles stronger and allow the agency to punish companies that don't treat all content equally on the Web.

Carriers argue that there aren't many examples of wrongdoing to warrant rules. Companies such as Skype and Sling Media, which had been blocked from AT&T's 3G wireless network for iPhone users, say such examples show the need for stronger net neutrality rules.

According to 4Chan's blog, signs that Verizon was blocking the site began late last week:

Over the past 72 hours, we've been receiving reports from Verizon Wireless customers having difficulty accessing the image boards.

After investigating, we found that Verizon is dropping traffic to/from, only on port 80 (HTTP). No other subdomain/IP/port is affected, which leads us to believe this block is intentional.

On Sunday, the company confirmed it was being blocked in a tweet to its 22,860 followers:

@cChan Received confirmation from Verizon's Network Repair Bureau (NRB) that we are "explicitly blocked."

"Carriers argue that there aren't many examples of wrongdoing to warrant rules."

So if there are no murders in our town this year, laws against murder are unwarranted?

Hey corporations, which is it? Do you want to be treated like human beings or not? Well of course it depends on the situation.

So, it's OK for Google to react to attacks from China, but not OK for Verizon to react to attacks from 4chan? Sounds as if a certain blogger is partial to Google.
