The issues for Facebook, Instagram and Facebook Messenger appear to be mostly affecting users in the USA, the United Kingdom and Brazil, while many WhatsApp error reports have come from Mexico and South America as well as Europe, according to the site.
"We're aware that some people are now having trouble accessing the Facebook family of apps", the spokesperson said.
Facebook is working to fix the issue.
Facebook took to Twitter to update users on the situation.
Earlier today, a lot of Google services were down and lot of users couldn't access services like Google Drive, Hangouts and among others.
"We know this is frustrating, and our team is hard at work to resolve this ASAP", wrote Instagram.
Often people were able to open the apps, but couldn't send or receive messages or post new content.
So of course, people are taking to Twitter for memes and mocking.
Both Facebook's desktop site and app appeared to be affected.
While it has not yet provided a reason for the outage, Facebook said it was not caused by a distributed denial of service (DDoS) attack.
It's not just your Facebook page that's down.
The service seems to be recovered in some places now according to users' reports, while others remain unable to log in.
Social media giant Facebook is in the midst of a worldwide outage this morning, with users reporting that they can't reach the company's main site or use the Instagram, WhatsApp and Messenger apps. However, the Google outage wasn't as widespread Facebook one.
As far as we're aware, Google is back to normal by now, and Facebook is still working to right its servers and connectivity.
That's a reference to a distributed denial-of-service brute-force attack, in which networks are overloaded with bogus traffic created to disrupt service.
Facebook was not immediately available for comment, so it was unclear whether the problems with Ads Manager were related to the mass outages affecting the rest of the social network.
