Signal is responding normally. Our last automated check of signal.org completed 5 minutes ago and succeeded in 459 ms. Over the past 24 hours the service answered 100.00% of our checks.
Measured from our automated checks, Signal has been available 100.00% over 24 hours, 99.85% over 7 days, 99.86% over 30 days. We have recorded no incidents in the last 30 days.
Signal has averaged 97 ms across our successful checks in the past 24 hours, which is fast — comfortably within what a healthy service should return. Response time is measured from our probe to signal.org and does not include rendering time in your browser.
Our probe is reaching signal.org normally right now, so the problem is more likely to be local to you than a full outage. Use the report button on this page to add your own signal — when several people report the same problem within a short window, it appears on the chart above.
Mobile apps and the website often run on different infrastructure. If Signal fails in the app but works at signal.org in a browser, an app update or a cache clear inside the app usually resolves it.
Open any other site. If nothing loads, the issue is your network rather than Signal. On Windows run ping signal.org and nslookup signal.org in Command Prompt; on macOS or Linux use Terminal. A DNS failure and a server failure look identical in a browser but are very different problems.
Load signal.org in a private or incognito window. If it works there, clear cookies and site data for signal.org in your normal browser rather than clearing everything.
Switch from Wi-Fi to mobile data, or vice versa. Regional ISP routing problems are common and often affect one carrier while others are unaffected.
