"I see 3 million new users signed up for Telegram within the last 24 hours", the Telegram chief said.
Reflecting that shift, the chief executive said that although Facebook meant to keep Messenger, Instagram and WhatsApp as separate apps it would work to provide interoperability for their messaging capabilities, and extend that interoperability to SMS messages.
Facebook is undergoing one of its most widespread and persistent system outages, with users across the globe unable to access its social network and services from Instagram to Messenger for much of Wednesday.
The social network´s handling of user data has been a flashpoint for controversy since it admitted a year ago that Cambridge Analytica, a political consultancy which did work for Donald Trump´s 2016 election campaign, used an app that may have hijacked the private details of 87 million users. When it comes to Facebook's long-term plans, that's bad news.
Facebook acknowledged the service interruption via Twitter, but it ruled out a possibility resulting from a distributed denial-of-service, or DDoS attack, on its platform or servers.More news: Armed Man Chased, Fired On New Zealand Mosque Shooter
Downtime attributed to a "server configuration change". "Good. We have true privacy and unlimited space for everyone".
Eventually, Facebook did come back online, though problems persist (you can check the Facebook Developer updates for the latest on resolving the issue). The encrypted messaging app does not have ads and runs on user donations.
Ironically, the biggest social network of them all made a decision to announce the end of the outage on a rival social media platform, Twitter.
The platforms had experienced issues especially when users tried to send and receive content and also when posting new material as well.
"It has already been reported that there are ongoing federal investigations, including by the Department of Justice", a Facebook spokesman said in response to an AFP inquiry.
