Users have been reporting that YouTube, Facebook and Snapchat are having problems, the online tracker Downdetector said.
As far as YouTube is concerned, the most commonly reported problems are related to accessing the website of the video-sharing platform as well as its streaming videos and server connection.
As of now, problems with accessing YouTube have been reported in the United States, Mexico, and Taiwan, Downdetector shows.
Also, some users have reported problems with Facebook.
"Nothing on Facebook is loading. My news feed is days old", a user told Downdetector.
Earlier in October, Facebook, WhatsApp and Instagram experienced a major outage worldwide, with the company's engineers later blaming it on disruption in operations caused by configuration changes on backbone routers.
