Starting Wednesday, January 14, 2026, the access URL for ONION-object related services will change.
Access to the old URL for ONION-object will be redirected to this page for the time being. Please update your bookmarks.

Additionally, if you are using ONION-object with an Amazon S3 connection, you will no longer be able to access it using the old endpoint URL, so please change to the new endpoint URL.
(On ONION-file and Gakunin RDM, the endpoint URL connected to ONION-object will be automatically updated, so no action is required.)

* The domain part of shared URLs that have already been issued will also be changed. Please notify the people you share your bucket with of the new shared URL.
