發生原因
network partition and subsequent database failure
A network partition refers to network decomposition into relatively independent subnets for their separate optimization as well as network split due to the failure of network devices.
也就是網路裝置與資料庫故障, 導致發生此一事件
影響範圍
this incident only impacted website metadata stored in our MySQL databases, such as issues and pull requests
Git repository data remains unaffected and has been available throughout the incident
因應處理
各計算機程式、電腦輔助設計與協同產品設計倉儲資料除了近端與 Github 端存放外, 還必須同步到:
https://about.gitlab.com/pricing/
https://bitbucket.org/product/pricing
以及自建區域網路上的 Fossli SCM 主機
Github Pages 靜態資料可以分別以:
https://about.gitlab.com/features/pages/
Pages for Bitbucket
以及 Fossil SCM 的 Documentation 技術達成
