Thank you for using the HENNGE One Service.
This announcement is for customers using the HENNGE Device Certificate service to manage Device Certificates.
Our HENNGE Device Certificate service utilizes the certificates issued via a third party certificate issuing vendor called CyberTrust.
In order to assure that the device certificate issuing service is up-to-date and running robustly, CyberTrust has scheduled the following downtimes for server maintenances.
We are truly sorry for any inconvenience caused during the downtimes.
From 22:00 of the second Wednesday of the month to 08:00 of the next day. （JST）
During the above times, device certificates cannot be issued.
Thank you very much for your understanding.
