Boeing declined to comment Wednesday on reports that the hacker group Anonymous had brought down the company’s website for two hours or more.

“I believe the website is up and running now,” said spokesman Todd Kelley. He wouldn’t say whether it had been functioning earlier, saying the company doesn’t discuss IT security matters.

According to several reports, Anonymous claims it disabled the Boeing website for a couple hours Tuesday afternoon as part of a protest against the proposed Cyber Intelligence Sharing and Protection Act (CISPA).

Bloomberg News also reported Tuesday that two technology trade associations said their websites were disabled a day earlier by so-called denial-of-service attacks led by the hacker-activist group over their support of the bill. Such attacks involve flooding a website with traffic, causing it to temporarily crash.
