Prefect Horizon's official status page is https://horizonstatus.io/posts/dashboard. Pingoru polls it every 5 minutes and renders the same data here, alongside every other cloud or SaaS provider you depend on — so you can spot multi-vendor incidents (e.g. AWS + Stripe + Cloudflare degrading at the same minute) without flipping between tabs.

We read https://horizonstatus.io/posts/dashboard directly, using Prefect Horizon's own status page. If the vendor reports an incident, you see it within one check cycle — not after someone manually marks the page as down.

Three common reasons: • A real Prefect Horizon incident that hasn't been acknowledged on their public status page yet — vendor status pages are updated manually and typically lag the first customer reports by 10–30 minutes. • A regional or account-scoped issue affecting a subset of customers — these rarely trigger a global status-page change. • A local problem: ISP / DNS / your own software. Try reproducing from a mobile data connection and from a different network to isolate. If you suspect a real Prefect Horizon issue that isn't reflected yet, contact their support to escalate. Subscribing here means you get the alert the moment they do post an update.

We use Prefect Horizon's own status page at https://horizonstatus.io/posts/dashboard and cross-reference their homepage (https://horizon.prefect.io). Nothing is read in a way the vendor hasn't explicitly made public — we use the same data their own dashboard uses. So our data is as accurate as what you'd see loading the status page yourself, but rolled into one dashboard alongside every other service you depend on.

All tracked Prefect Horizon components are reporting operational. No incidents are currently affecting service.
