Update 2: Signal is now back up for "99% of users," according to its Twitter account.
Update: In a tweet, Signal said the disruption is due to a hosting outage.
Signal is down for many users right now. Its status website says the encrypted messaging app is "experiencing technical difficulties" and many people are getting an in-app error message that says the same thing. The company says it is "working hard to restore service as quickly as possible." TechCrunch has contacted Signal for comment.
Signal's in-app error message
According to Downdetector.com, users started reporting outages around 11:05 PM Eastern Standard Time this evening, and it appears to be affecting people around the world.
In January, Signal experienced a surge in downloads on the App Store and Google Play after WhatsApp changed its data-sharing policy.
Over the past few months, Signal has continued to build out its feature set, adding a default timer for disappearing messages that automatically applies the settings to all new conversations.
