We are pleased to confirm that as of 9 February 2026, the IRUS-UK service has resumed processing OAPEN Library usage data. The Dashboard is now receiving updates again, and publishers will have access to current usage statistics going forward.
However, we must also share disappointing news: data from the period between 17 October 2025 and 9 February 2026 cannot be recovered.
What happened?
On 17 October 2025, IRUS-UK stopped making OAPEN usage data available via their API. Throughout the entire period, our logs – verified with CERN – confirm that we continued to send complete usage data without interruption. The issue was on the IRUS-UK side, not ours.
We were in regular contact with Jisc, providing logs and assistance to help resolve the problem. We also kept publishers informed – everyone who contacted us received the information we had at the time.
Why the data cannot be recovered?
IRUS-UK has confirmed that its system does not accept retrospective data. Once the interruption occurred, the data for those months was effectively lost. No amount of effort on our part – or theirs – can restore it.
We understand how frustrating this is. Usage data is essential for demonstrating impact, reporting to funders, and understanding readership. A gap of nearly four months is a real loss, and we are deeply sorry.
What now?
The good news is that the feed is now working again. Current data is flowing, and the Dashboard will reflect new usage from this point forward.
IRUS-UK will be retired in April 2026, and we are building a modern, sustainable analytics infrastructure that we will fully control – one that will not leave publishers in this position again.
Thank you!
To everyone who contacted us, asked questions, and stayed patient through this: thank you. We know this has been difficult, and we are grateful for your understanding.
If you have questions about specific titles or need assistance interpreting the available data, please reach out. We are here to help.
