Thank you very much for your continued patronage of our services.
This is the Tatsuno Information System learningBOX security team.

From Thursday, April 1, 2021Server maintenance is performed about once a month.
In order to protect our customers from the recent security threats, we have decided to perform periodic maintenance from 4:00 AM to 5:30 AM.

This will allow you to operate your server with the latest server-related security patches, including the latest security patches for middleware, applied to your server.

We will be performing server maintenance as follows.
Please note that the website and services will be temporarily suspended during the maintenance work.

Regular: About once a month 4:00~5:00 a.m. (This is irregular because it includes emergency security patches.)
Start of implementation: From April 2021
During the above time, the system will be switched to the maintenance screen and the system will not be available.

We apologize for any inconvenience this may cause you, but we would appreciate your understanding and cooperation as we work to prevent the threat of personal information leaks.

We look forward to working with you in the future.
