Planned Maintenance - Cirium Sky Schedule Files - 1st Septmber 2026

Scheduled for Sep 1, 00:30 - 04:30 UTC

Scheduled

Cirium Sky™ Schedule Files will be undergoing maintenance, on Tuesday 1st September 2026 from 00:30 to 04:30 UTC as part of a planned maintenance window.

During this period, the backend SFTP server will be migrated from Windows Server 2012 R2 to Windows Server 2022. The customer-facing SFTP endpoint, ftp.us.cirium.com, will remain unchanged, however customers may receive a host key verification/change warning when connecting for the first time after cutover.
• Interactive users will typically need to accept the new host key once.
• Automated jobs, scripts, or applications that perform host key validation may require an update after the migration.

We will be on hand to provide migration support after the cutover. Please feel free to contact us if you have any concerns or questions.
