Update 2: Signal is now back up for “99% of users,” according to its Twitter account.

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.

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.
