System update of Tsukuba Repository will be performed as follows.
During the emergency maintenance, services including repository search and browsing will be unavailable.

Thursday, September 19, 2024, 10:00 - 12:00 (scheduled)　→Finished.

*The developer of the Tsukuba Repository has informed us that the server load has been high since the resumption of service yesterday (9/17), and that emergency maintenance with service suspension will be performed again during the above time period in order to implement countermeasures against this situation.
 As a result, Tsukuba Repository services including search and browsing will be unavailable.
 Even after the emergency maintenance is completed and the service is resumed, new registrations and modifications of registered items will not be available until an announcement is made by the developer. We will continue to accept registration requests, but we will not be able to respond to them until the developer makes an announcement. 

As soon as we receive an announcement from the system developer, we will post it on this page.

Service has resumed, but there is a problem after the system update. Please check the Tsukuba Repository top page for details.
