Accepted Answer

Over the last 90 days, Crossref reported 97.97% uptime on its official status page.

Question 2

Has Crossref had outages in 2026?

Accepted Answer

Yes — Crossref has had 29 incidents reported on its official status page so far in 2026. The full timeline (start times, durations, components affected) is shown above on this page. Pingoru re-checks the status page every 5 minutes so the count stays current.

Question 3

When was the last Crossref outage?

Accepted Answer

The most recent Crossref incident was "Content registration processing delays today", which started on September 9, 2026 and was resolved on September 9, 2026. Pingoru captured this directly from https://status.crossref.org. See the full incident card above for affected components and the update timeline.

Question 4

How often does Crossref have outages?

Accepted Answer

Based on the last 90 days, Crossref averages 9.7 reported incidents per month on its official status page. Pingoru tracks each one with start time, duration, severity, and affected components — so you can see the pattern at a glance instead of digging through the vendor's archive.

Question 5

Where is Crossref's status page?

Accepted Answer

Crossref's official status page is https://status.crossref.org. 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.

Question 6

Is Crossref down right now?

Accepted Answer

Crossref is up. Pingoru checks the official status page every 5 minutes and flips this headline the moment Crossref reports a change. Current status is based on 31 tracked services.

Question 7

How does Pingoru know if Crossref is down?

Accepted Answer

We read https://status.crossref.org directly, using Crossref'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.

Question 8

Where can I get notified when Crossref has an outage?

Accepted Answer

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

Question 9

Crossref's status page says the service is up, but I'm having issues — what's wrong?

Accepted Answer

Three common reasons:

• A real Crossref 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 Crossref 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.

Question 10

Where does Pingoru get the official Crossref status?

Accepted Answer

We use Crossref's own status page at https://status.crossref.org. 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.

Question 11

What does "Up" mean?

Accepted Answer

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