Is Calibre down?

Over the last 90 days, Calibre reported 99.89% uptime on its official status page. That figure is calculated from the public incident timeline at https://www.calibrestatus.com — each minute of degraded, partial-outage, or major-outage status counts against the total.

Calibre has had zero incidents reported on its status page so far in 2026 — that's the official record. Pingoru tracks the page every 5 minutes; if a new incident appears, we'll capture it within that window.

Pingoru hasn't recorded any Calibre incidents within our retention window. That doesn't mean Calibre has never had an outage — only that we haven't seen a new one cross our 5-minute polling cycle in the period we display. Sign up free and you'll be alerted on the first one we do detect.

Calibre has been quiet over the last 90 days — fewer than one reported incident per month. Sign up free to be alerted the moment that changes.

Calibre's official status page is https://www.calibrestatus.com. 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.

Calibre is down. Pingoru checks the official status page every 5 minutes and flips this headline the moment Calibre reports a change. Current status is based on 21 tracked services.

We read https://www.calibrestatus.com directly, using Calibre'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.

Create a free Pingoru account and add Calibre as a monitor. You can filter to specific services, pick severity thresholds, and route alerts via email, Slack, Discord, or a webhook.

Three common reasons: • A real Calibre 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 Calibre 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 Calibre's own status page at https://www.calibrestatus.com. 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.

Calibre is reporting a major outage. A significant portion of the service is unavailable.
