Signal is facing an outage globally — thousands of users are reporting errors to site status tracker DownDetector, and Gadgets 360 confirmed this for ourselves as well. Although you can open the app and send messages, nothing is actually being delivered right now. The issues seem to have started about one hour ago at 8.30pm IST on Friday, and appears to be a global outage. The Signal handle on Twitter has not posted any update yet, at the time of writing.
Both Signal and Telegram have seen a huge influx of users as a result, with Signal becoming the number one messaging app in many markets. A tweet by Signal CEO Moxie Marlinspike from earlier in the week had noted that the entire small non-profit team at Signal was working late nights and weekends to keep Signal running.
