To ensure stable and secure service, we will be conducting the following maintenance as outlined below:

■ Schedule
Date & Time: Wednesday, July 30, 2025, from 4:00 AM to 6:00 AM (UTC)
Details: network firewall security patch and system upgrade
Expected Impact:
The network firewall will be switched twice during the upgrade, which may result in brief network interruptions of about 1–2 seconds each time.
No impact is expected on general service traffic, but intermittent chain synchronization issues may occur.

This maintenance is a necessary step to ensure stable and reliable service operation, and we will do our utmost to minimize any potential impact during the process.

We kindly ask for your understanding and appreciate your attention to this notice.
Thank you.
