We would like to inform you that we will be performing maintenance on the security feature (DNS filtering) linked to the KUINS DNS server on the date and time below.

Due to the impact of this work, there may be instances where DNS name resolution takes time.

We apologize for any inconvenience this may cause and ask for your understanding and cooperation.

• Date and Time / Target Device :
  • September 3, 2025, from 12:00 PM to 12:45 PM  /  10.224.254.21 , 10.224.253.11 , 10.224.254.1
  • September 8, 2025, from 12:15 PM to 12:30 PM  /  10.224.253.1
• Target Device: 10.224.254.11
• Details of Work: Configuration changes to the linked security feature (DNS filtering) and a subsequent restart of the DNS service.
• Impact of Work: During the work period, the DNS name resolution may become unstable, and some users may experience delays in network access.

We would like to inform you that on September 3, we experienced an issue following a change to the external cloud service for our DNS filtering function, which verifies the safety of websites and other connections. An outage at the new external cloud service caused delays in name resolution for some websites, leading to unstable connections.

Therefore, we have reverted the settings to their previous state. Additionally, the scheduled change for September 8 has been postponed indefinitely. We will announce the new implementation date as soon as it is decided.

We sincerely apologize for any inconvenience and trouble this may have caused. We appreciate your understanding and cooperation.
