Planned Maintenance - Cirium Sky Warehouse - 14th July 2026
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jul 14, 2026 - 09:00 UTC
Scheduled - We are updating aircraft manufacturer information across our historical and live aircraft data. As part of this change, a data refresh is required for Tracked Utilization (TU) data in Sky Warehouse.

During the refresh window, Tracked Utilization data may appear temporarily out of date between 09:00 and 11:00 UTC on Tuesday, 14 July while downstream systems are reprocessed.

The refreshed data, including the updated manufacturer information, is expected to be available from 12:00 UTC onwards once processing has completed. During this period, you may notice temporary differences between related datasets as updates propagate through downstream systems.

We apologise for any inconvenience and appreciate your patience while these updates are being applied. If you have any questions or are interested in understanding what specific changes are happening, please contact the Cirium Support team.”
