What does Signal's response time mean?
Response time measures how long signal.org takes to reply to our server-side probe. Under 500ms is good, 500–1000ms is elevated, and over 1000ms suggests degraded performance. Your experience may differ based on your location and ISP.
Is Signal experiencing a global outage?
