Social media networks, Facebook, WhatsApp and Instagram, were inaccessible to some users across the world on Sunday, according to Downdetector.com, a website which monitors outages.
The outage tracking website showed that there are more than 9,000 incidents of people reporting issues with Facebook.
Separately, Downdetector.com also showed that there were issues with WhatsApp and Instagram, but with a relatively lower count of outage reports.
Facebook had experienced one of its longest outages in March, when some users around the globe faced trouble accessing Facebook, Instagram and WhatsApp for over 24 hours.
