Due to adjustments in upstream network resources and routing architecture, and in order to ensure long-term service stability and improved network performance, we will be performing an IP address change maintenance for selected instances in the Hong Kong region.
We have also observed intermittent connectivity issues in this region. This maintenance is expected to significantly improve overall network quality and service reliability.

📌 Scope of Impact
Affected Product:
Hong Kong Region Prime Secure (PS)

🕒 Maintenance Window
January 11, 2026, 00:00 – 05:30 (UTC+8)
The operation will be carried out in batches to minimize service disruption.

🔄 Possible Impact
During the maintenance, you may experience:
Brief network interruptions or reconnections
Automatic instance reboot
Assignment of a new IP address after completion
No service data or system configuration will be affected.

👉 Required Actions After Maintenance
Please ensure you update the following accordingly:
DNS records

If you require IP replacement without reboot (no service interruption):

You will need to manually configure the new IP address
⚠️ If Cloud-Init is disabled or a custom/DD image is used, manual network configuration is required.
