The postponed maintenance to switch the connection destination for the KUINS DNS filtering security function has been rescheduled for the following date and time.

During this work, you may experience delays when accessing websites or other network services. While the DNS service will remain available overall as we will be restarting servers sequentially, please be aware that a temporary connection loss may occur if your device is configured to use only one of the DNS servers.

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

• Date and Time : June 24, 2026, from 12:00 PM to 1:00 PM
• Target Device: 10.224.254.21, 10.224.254.1, 10.224.253.11, 10.224.253.1
• Details of Work: Configuration changes to the DNS filtering security function and subsequent DNS service restarts.
• Impact: During the maintenance window, DNS resolution may become unstable, leading to delays or temporary inability to access the network.
  • Please take extra caution if you have manually configured your device to use only a single DNS server.
