The tech titan Facebook owns both the Instagram and WhatsApp social media platforms.
Facebook, Instagram and WhatsApp are experiencing technical problems this afternoon, leaving users across the globe frustrated.
This is the latest outage ever since Facebook faced its biggest one last month.
Facebook has not responded to an e-mail requesting comment about the outage. "We are investigating the issue and working on a resolution", Facebook wrote, adding that it was "investigating". Text messaging service WhatsApp is also reportedly having issues.
Those trying to log on have met an error message saying the site "can't be reached".
Some of the services are back up but seem to be intermittent.
