Summary of Impact: Between 00:57 UTC and 03:40 UTC, 20 November 2019, customers and services utilizing Azure Front Door (AFD) services were impacted by an infrastructure service failure. This resulted in a loss of connectivity to multiple services reliant on AFD. Azure Front Door services provide Edge caching and network entry point services to the Microsoft global network. This issue impacted a large percentage of Microsoft Services, though not all services were impacted. Many impacted services were able to initiate fail over from the AFD platform, providing immediate mitigation to their customers.

Preliminary Root Cause: During a recent periodic deployment, initial safety checks did not detect issue and prevent the roll out. Monitoring detected immediately once service failure was experienced. Engineers were alerted immediately, and immediately initiated roll back.

Mitigation: Engineers immediately initiated deployment rollback processes to correct the underlying Azure Front Door Issue, this was completed at 02:40 UTC 20 November 2019. Impacted services began recovering at that time.

A small subset of services may still be experiencing residual impact; customers will be communicated directly via Azure Service Health for those services.

A detailed root cause analysis will be published within 72 hours.

看你注重什么 如果要好好传输，原厂的固件不要动，原厂针对 Wi-Fi 驱动都是有优化的，

顺便搭车问一下 azure 的高级解决方案架构师认证，

Coremark 51200

@leavic Quad Cortex A72 ARM 全功率版本，可以和小米 8，845 阉割版 pk
为什么同样的架构不同厂商出来的性能相差很大，也是有原因的

商业帝国：没有永远的敌人，也没有永远的朋友
1、收购 github
2、Microsoft Learn
3、微软重视的产业模块，都有推出教育计划
4、docs.microsoft.com ，全部都是 GitHub 开源托管
培养从 0 开始的习惯（巩固生态），一步一步的降低基础模块的成本（学习成本），这种布局非常恐怖；

有多少人上船，楼主可以看看 azure 和 office 的财务报表就知道了，说的有点笼统；
（并不是说微软的东西有多好，是性价比太高，基础部分在产品上平坦成本很低）

可玩性也不错，可以提供源码

@greenlake 对比一下生效时间 你就知道厉害了

@chinawrj 哥们留一个邮箱有偿请教无线组播问题

1、我们最开始使用 fastmail+坚果云，使用期间，有的同事手机访问邮箱很慢，尤其是大附件，坚果云 mac 客户端只能说能用的级别，经常编辑 office 文档协做，很容易出现版本冲突产生副本。
2、 后面换成 Office 365 Microsoft 365 Business HK$155.00 使用者 /月。邮箱很 OK，onedrive 很头疼，经常出现文件不上传。公司网络是 sd-wan 直通香港服务器，不存在网络问题。
3、目前老老实实 office 365 邮箱，teams 内部沟通+dropbox 协作（存在感极低），云端文件有 90 多 G

留一个记号！ 以防后患

凡是和延时挂钩的需求，都不要采用中继方案

我们团队使用 office365 全套，产品迭代、功能叠加、重视程度，越来越不像微软了！

坐标？技能？ 来我们公司吧
