Scheduled System Maintenance: Suspension of DIAS Services (August 21–26, 2025)

Due to legally mandated inspections at the facility where the DIAS system is hosted, all DIAS services will be temporarily suspended during the following period:

During this period, all DIAS services will be unavailable, including but not limited to:

• DIAS web applications
• Dataset search and download
• Requests for permission to use dataset
• All analysis environments

Please note that this website (diasjp.net) will remain accessible throughout the maintenance period.

Service restoration will begin in the morning of August 26, and full system functionality is expected to resume by late afternoon on the same day.
Please note that this schedule is subject to change depending on the progress of the maintenance work. Any updates will be posted on this page.

Any missing data during the suspension period will be supplemented after all systems have been fully restored.

We apologize for the inconvenience and sincerely appreciate your understanding and cooperation.
