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 Ably does
Ably provides realtime messaging infrastructure, handling pub/sub channels, presence, push notifications and message queues over persistent connections. Applications use it for live chat, collaborative editing, live scores and location tracking, where the value is in delivery within a second. It is embedded inside other products, so its failures appear as a customer's own app going quiet.
What an outage looks like
Clients disconnect and reconnect repeatedly, or connect and then receive nothing. Live features stop updating while the rest of the application keeps working, so the page looks healthy but frozen. Presence lists show users who have left or omit users who are there. Push notifications stop arriving on devices while in-app messages still flow, or the reverse.
What to do about it
status.ably.com reports 18 components across three groups, Pub/Sub, Push Notifications and Queues, each broken down by region including Northern Virginia, Ohio, Northern California, Ireland, Frankfurt, Singapore and Sydney. Ably Platform, the Control API and Integrations report separately from the message path, so provisioning can fail while existing channels are fine. Client libraries reconnect on their own, so avoid forcing reconnection loops that add load to a recovering region.
Is it down for everyone, or just you?

How we measure this
- We request Ably'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 Ably 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.
