"Yesterday, a server configuration issue made it hard for people to access our apps and services". In any case, a contact within Telegram confirmed to TechCrunch's colleagues what was already quite obvious: the merit of this sudden growth is the aforementioned problems ("These outages always drive new users"), but is partly attributed to the will of a growing number of users to distance themselves from Facebook.
As of Thursday, downdetector.com showed 37 percent of problems Thursday morning related to log-in; 32 percent with loading the newsfeed; and 30 percent a total blackout.
