Washington: Social networking site Facebook went down in Sweden, Denmark, Ireland, Norway and Portugal on Thursday, according to reports that streamed in via Twitter.
There is a "likely service disruption" on Facebook, according to the website Down Right Now.
The site gathers its information by using a few different techniques like searching for an official site announcement, Twitter reports or direct reports to the site.
According to CBS News, a Twitter account associated with the hacking group Anonymous claimed responsibility for the attacks on Facebook in Europe.
“I`m attacking facebook rigth now,"[sic] @AnonymousOwn3r tweeted.
According to the report, it`s still not clear if the outages are a hoax being played out on Twitter or if they are real.
