About the error occurrence of CiNii Research Institutional Authentication (Wed., April 13 7:16-10:16)

On Wednesday, April 13th, 7:16-10:16, there was an error in the CiNii Research Institutional Authentication. Due to this error, IP authentication and Shibboleth authentication from the user of Institutional authentication could not be used during the relevant time period. Now that the cause has been identified, we will inform you as follows.

  1. CiNii Research's authentication file server has been restarted due to a source shortage caused by a work error.
  2. Due to a problem with the authentication server startup confirmation method, CiNii Research search system determined that the server was down and disconnected the authentication function.
We apologize for the inconvenience this time. We will strive to prevent recurrence in the future.
