🚨 紧急安全维护通知 | Emergency Security Maintenance
为缓解近期披露的 Januscape（CVE-2026-53359）安全风险，并保障 ISIF 虚拟化平台的安全与隔离性，我们将对全球 KVM 虚拟化节点开展紧急维护。

🕙 开始时间
2026 年 7 月 7 日 22:00（UTC+8）
2026 年 7 月 7 日 14:00 UTC

🌍 影响区域
ISIF 全部数据中心地域

⚙️ 可能影响
部分 KVM 虚拟机可能出现一次短暂重启或临时服务中断。
本次维护将按地域与节点分批进行，相关宿主机及虚拟化组件将执行必要的受控重启与缓解措施，以尽量降低同时受影响的范围。
除非另行通知，客户目前无需执行额外操作。维护完成后的节点将继续接受稳定性与安全状态监控；如仍需进一步更新内核或虚拟化组件，我们将另行通知。

🚨 Emergency Security Maintenance Notice
To mitigate the security risk associated with the recently disclosed Januscape (CVE-2026-53359) vulnerability and maintain the security and isolation of the ISIF virtualization platform, emergency maintenance will be performed on KVM virtualization nodes across all ISIF locations.

🕙 Start Time
7 July 2026, 22:00 UTC+8
7 July 2026, 14:00 UTC

🌍 Affected Locations
All ISIF data center locations

⚙️ Potential Impact
Some KVM virtual machines may experience a brief reboot or temporary service interruption.
Maintenance will be carried out in batches by location and node. Relevant hosts and virtualization components will undergo controlled restarts and mitigation work to minimize simultaneous customer impact.
No customer action is required at this time unless otherwise notified. Completed nodes will remain under stability and security monitoring. Any further kernel or virtualization-component updates will be announced separately if required.
We apologize for any inconvenience this may cause and appreciate your understanding.
