[Aug.27 Update] Scheduled System Maintenance: Suspension of DIAS Services (August 21–26, 2025)

[Update 2025/08/27 09:00 JST/GMT+9]

All systems have now been restored. If you encounter any issues that appear to be malfunctioning, please notify the DIAS Secretariat. Additionally, depending on the dataset, heavy download traffic may cause temporary overload. We kindly ask for your cooperation in load balancing by avoiding excessive access and adjusting your access times.

Please note that we have begun the process of restoring data from the service suspension period. We ask for your patience as this work progresses.

Furthermore, as previously announced, due to mandatory inspections at another facility, XRAIN data prior to 2023 and S-uiPS will be temporarily unavailable. We sincerely apologize for these consecutive service interruptions and appreciate your understanding.

[Update 2025/08/26 19:30 JST/GMT+9]

We are currently working to restore the system in stages, but some applications and services have not yet been restored. Full restoration is now expected to be delayed until tomorrow, the 27th.

Please note that even applications currently available may become unavailable without prior notice. Please refrain from downloading large amounts of data until further notice on this page.

We sincerely apologize for the inconvenience caused by this delay in restoration.

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.
