Frequently asked
What HTTP status codes does Signal return?
Signal currently returns HTTP 200. Status 200 means OK, 3xx means redirect, 4xx means client error, and 5xx means server error.
How does WebsiteDown check Signal?
We send a direct HTTP HEAD request to signal.org from our serverless infrastructure, measuring the response time and HTTP status code. We also scan social networks, Reddit, and news sources for outage signals.
Where can I see Signal incident history?

Is Signal experiencing a global outage?
Our probe checks signal.org from a single serverless region. If the service is up in our check but down for you, the issue may be regional — related to your ISP, local DNS, or geographic routing.
Can I still make calls on Signal during an outage?
During partial outages, some Signal features like messaging may work while video calls don't, or vice versa. Try switching between features or use the mobile app as a fallback.
Are Signal messages delayed during outages?
Yes, messages sent during a Signal outage may be delayed or fail to deliver. They typically arrive once the service recovers. Check this page for live status updates.
