Cloudflare 计划性维护会在状态页通过日更的日历发布。
在维护窗口期间,位于维护状态的边缘节点到达时间可能略有增加。
计划性维护也可通过 Cloudflare 通知(Cloudflare Notifications) 推送通知。
Maintenance Notification
Who is it for?Customers interested in knowing about planned Cloudflare maintenance for specific data centers. The notification lets you know when maintenance has been scheduled, changed, or canceled on an entire point of presence.
Other options / filtersYou can filter maintenance notifications for specific points of presence and updates (scheduled, changed, canceled).
Included withAll Cloudflare plans.
What should you do if you receive one?If the notification is announcing new scheduled maintenance, you may want to add the maintenance to your calendar. During these maintenance windows, you may experience a slight increase in latency to the edge location which is under maintenance.
有关如何设置警报的更多信息,请参阅 Cloudflare Notifications。
Cloudflare 使用具备冗余能力的 Anycast 网络 ↗(anycast)。当某地区需要非计划性维护或发生紧急事件时,系统可自动将该地区从网络中摘除,并自动将流量迁移到其他可用地点。
可通过状态页确认非计划维护:若某地点状态显示为“Re-routed(已重路由)”,即说明已重路由(https://www.cloudflarestatus.com ↗)。在少数情况下,某地点的维护会以“事故”形式发布,此时请在 https://www.cloudflarestatus.com ↗ 查看更新。
如果你在该重路由站点有 Cloudflare 的 CNI 连接,则在计划性或非计划性维护期间该连接可能暂时不可用,系统会改用常规公网路由访问你的网络。
在 Magic 系列产品中,路由通过 静态路由 显式定义,并按客户设置的优先级将流量导向指定隧道。若你有 CNI 隧道,建议再配置一条备用隧道(如 Internet 回退隧道),以保证流量始终可达。
