Reachability by region

Each region runs its own request from a different part of the world. A service can be up for one continent and down for another, which is usually the first sign of a routing or CDN problem.

What Signal does

Signal is an encrypted messenger run by a non-profit foundation, offering private messages, groups and calls with end-to-end encryption by default. People use it for conversations they consider sensitive, and often as their only channel with certain contacts, so an outage removes a line of communication that has no obvious substitute.

What an outage looks like

Messages stay marked as sending and never show as delivered. Incoming messages stop arriving, so a conversation looks quiet rather than broken. Voice and video calls fail to connect or drop on answer. Registering a new device or transferring to a new phone fails, which is the step that leaves people genuinely stuck rather than merely delayed.

What to do about it

Check status.signal.org, which reports whether Signal is operating rather than breaking the service into many components. Messages you send are queued on your device and deliver once the service returns, so avoid resending them repeatedly. Postpone changing phones or re-registering until the status page is clear, because that path needs Signal's servers.

Is it down for everyone, or just you?

If this page says Signal is up but it is not loading for you, the problem is between you and them. Run a check against any URL from all 18 regions to find out where it breaks.

Signal outage FAQ

Are my messages lost if Signal goes down?
No. Messages you send are held on your device and delivered when the service returns, and messages sent to you are queued by Signal for delivery. The encryption model means Signal cannot read them regardless. What you lose is timeliness, not content, so resending the same message mostly produces duplicates for the recipient.
Is Signal down or has my contact blocked me?
Blocking produces messages that appear to send normally and are never delivered, with no error, which is deliberately indistinguishable from a delay. An outage affects everyone, so check status.signal.org and whether messages to other contacts are also stuck. If only one conversation is affected while others flow, the cause is not an incident.
Should I re-register or reinstall during an outage?
No, and this is the one action that can genuinely cost you. Registration requires Signal's servers, so reinstalling during an incident can leave you unable to complete setup, and reinstalling without a backup loses message history permanently. Wait for the status page to clear before touching the installation.
Does an outage affect the security of my messages?
No. Messages are end-to-end encrypted between devices, and an availability incident means servers cannot relay them rather than that anything is readable. Signal is designed so that the relay does not have access to content in the first place. The failure is delivery, and it has no bearing on privacy.
Why do calls fail when messages eventually arrive?
Calls need a real-time connection established through Signal's servers, while messages tolerate delay and can be queued. During a partial incident, messaging degrades gracefully and calling does not, so a call fails outright while a text arrives a minute late. Falling back to messages during a call outage usually works.

How we measure this

  • We request Signal's public endpoint every 6 hours from Fly.io regions across six continents — 8 of them answered the most recent check.
  • A region counts as down only when it gets no usable HTTP response. A 403 or 429 means the origin answered and refused us, which we report as blocked, never as an outage.
  • A single failing region is treated as probe noise. We only change the verdict when two consecutive cycles agree.
  • Response times average only the regions that actually served the page, so a timeout never inflates the number.
  • Where Signal publishes an official status feed we read it too, and let it override us in both directions.
