TOKYO (BLOOMBERG) - The use of Snapchat surged more than 20 per cent after Facebook's services went down for six hours on Monday (Oct 4), the biggest winner among rival apps during the American social media giant's worst outage in years.
Facebook blamed network configuration glitches for immobilising a suite of apps from Messenger to Instagram and driving some of its 2.7 billion daily users to the competition.
Snapchat saw a 23 per cent boost in time spent on its Android app on Monday compared with the same day the prior week, according to Sensor Tower data shared with Bloomberg News.
That led gains in activity on apps from Telegram and Signal to Twitter and ByteDance's TikTok on Monday, the mobile researcher said.
The service disruption, which Facebook blamed on a faulty network configuration change, hit small businesses and gave ammunition to critics and legislators arguing that the company has grown into an unwieldy monopoly that should be cut down to size.
Telegram founder Pavel Durov said his app added 70 million users and set new highs for registrations and activity on Monday. It jumped to the top of the Apple App Store as the most-downloaded free app in 40 markets, while Signal was No. 1 in Poland and in the top 10 in 35 markets, Sensor Tower said.
Alternatives like Telegram, which closely matches the look and functionality of WhatsApp, have historically added millions of users every time the world's most popular messenger app has had a significant outage, though many quickly return to the Facebook-owned app once it is back online.
"We've spent the past 24 hours debriefing how we can strengthen our systems against this kind of failure," Facebook chief executive Mark Zuckerberg wrote in a note to employees on Tuesday.
"The deeper concern with an outage like this isn't how many people switch to competitive services or how much money we lose, but what it means for the people who rely on our services."
