OneSignal uptime
Measured from multiple regions every 6 hours. Percentages count only checks that returned an availability answer — 55 days measured so far. A dash means that window does not yet hold enough measured days to publish a figure.

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 OneSignal does
OneSignal delivers push notifications, in-app messages, SMS and email for mobile and web applications. It describes itself as serving more than 2 million businesses. Products use it as the delivery layer for transactional alerts and marketing campaigns alike, so an outage shows up as silence, with users simply never receiving the message, rather than as a visible error inside the product.
What an outage looks like
Notifications are accepted by the API but never arrive on devices, which is the hardest failure to notice because nothing errors. Scheduled campaigns and Journeys stall partway through a send. The dashboard is slow or will not load delivery reports, and analytics numbers flatten. In-app messages stop appearing while push still works, since OneSignal tracks those channels separately.
What to do about it
status.onesignal.com separates Dashboard and UI from APIs and SDK Endpoints, Messaging Delivery, Analytics and Reporting, Journeys and Integrations, so a reporting problem is distinguishable from a delivery one. Check Messaging Delivery before resending anything: a queued send that eventually lands will duplicate if you fire it again. Apple and Google push gateways sit downstream and can fail independently.

How we measure this
- We request OneSignal's public endpoint every 6 hours from Fly.io regions across six continents — the most recent check ran from 8 of them.
- A region counts as down only when it gets no usable HTTP response. A
403or429means 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 OneSignal publishes an official status feed we read it too. An all-clear from the vendor can soften an unconfirmed degradation; a vendor-declared outage only worsens our verdict when our own checks corroborate it.
