Facebook responded to speculation that it was hacked on March 13 as the social media giant grappled with a website outage affecting millions of people across the world and in the United States.
“We’re aware that some people are currently having trouble accessing the Facebook family of apps,” it tweeted about two hours into the outage.
Facebook-owned Instagram and WhatsApp were also down for many.
“We’re working to resolve the issue as soon as possible,” said the firm.
It later added: “We’re focused on working to resolve the issue as soon as possible, but can confirm that the issue is not related to a DDoS attack.”
However, Facebook didn’t elaborate on why its websites or apps were down.
“I’ve never seen it down this long. Unreal,” wrote one person.
Some users said they couldn’t log into the website, some said they couldn’t post, some said they could sometimes post, and some said they could still “like” posts.
“Unable to comment on anything. Can’t upload photos. But can post,” wrote one person.
A number of people went on Twitter, which isn’t owned by Facebook, to express their frustration.
Hashtags #FacebookDown and #InstagramDown were the top spots in Twitter’s trending section for most of the day.
Other details aren’t clear.
