Facebook Inc said on Friday its services were being affected by a number of issues, after nearly a million people across the world reported problems with its photo-sharing app Instagram.

“Multiple teams are working on it (the outage), and we’ll update you when we can,” Facebook’s gaming unit said in a tweet.

Later on Friday night, the Facebook, WhatsApp and Instagram services were restored.

Outage tracking website Downdetector.com showed there were 1 million incidents of people reporting issues with Instagram and WhatsApp on the website.
