Privacy-focused messaging app Signal is back online after an outage lasting more than 24 hours, an extended downtime caused by a large rush of users switching to the app.
Late on Saturday night, Signal posted to Twitter that it was operational once again. Expressing the news using a gif from the movie "Rocky," the app claimed it had "learned a lot since yesterday," as well as thanking the "millions of new Signal users" for their patience.
"Your capacity for understanding inspired us while we expanded capacity," the tweet concluded.
Signal is back! Like an underdog going through a training montage, we've learned a lot since yesterday — and we did it together. Thanks to the millions of new Signal users around the world for your patience.

The tweet was posted after a lengthy downtime period that went on for more than one day, prompted by a lack of capacity on the app's servers to manage the sudden influx of users. Signal advised of its technical difficulties on Friday, the followed up with regular updates explaining its teams were working to get the app "up and running" as soon as possible.
"We have been adding new servers and extra capacity at a record pace every single day this week nonstop, but today exceeded even our most optimistic projections," one update tweet read. Another explained existing users may "see errors in some of their chats," indicating a message was missed from a contact rather than any issues with chat security.
