We’ve asked Facebook if it can comment on the outage.

There has been a string of problems across the services in recent months, with roots in everything from server configurations to the previously mentioned media services. It’s not clear why they’ve picked up after a long period of relative stability. However, Facebook has continued to grow rapidly in recent months, with 2.4 billion monthly active users as well as 2.7 billion people using its combined apps (including Instagram, WhatsApp and Messenger) in a similar period. That’s a lot of demand to deal with, even for a company with a vast infrastructure.
