(CBS News) GoDaddy, the domain registrar and Web hosting company, is down, perhaps taking millions of websites down as a result.
"Status Alert: Hey, all. We're aware of the trouble people are having with our site. We're working on it," @GoDaddy tweeted Monday.
While GoDaddy.com's site is up and running, websites hosted by the company are still experiencing outages.
TechCrunch reports that GoDaddy email addresses are down, as well. The blog suggests customers concerned with that their site has been affected can check online status at Down For Everyone Or Just Me.
A quick call to the company's customer service line resulted in a voice message stating that the company is aware of issues involving several services, including web hosting and emails. The company suggest following its Twitter page for updates.
Twitter accounts claiming to be associated with the hacking group Anonymous claimed responsibility for the attack.
"Basically, every GoDaddy site on the planet just crashed," @TibitXimer tweeted.
"#TangoDown - godaddy.com," @AnonOpsLegion tweeted Monday, claiming that the Twitter account @AnonymousOwn3r was responsible for the breach. "TangoDown" is the term that Anonymous generally uses to signify that a website is down.
"By using / supporting Godaddy, you are supporting censorship of the Internet," @AnonOpsLegion tweeted again later.
GoDaddy was the target of protests after it was discovered that the company supported unpopular bills the Stop Online Piracy Act (SOPA) and Protect IP Act (PIPA).
GoDaddy did not immediately respond to CBS News' request for comment.
The company's latest tweet reads,"So many messages, can't get to you all... Sorry to hear all your frustration. We're working feverishly to resolve as soon as possible."
