Cloudflare outage caused by bad software deploy

Cloudflare 官方網誌上的文章：

「今天 (7/2) 造訪 Cloudflare 的人，大約有 30 分鐘會收到 502 錯誤，這是 CPU 使用量飆升所造成 (...) 並非 (如部分推測所言) 是攻擊」

機器狼今天很有精神呢汪

"For about 30 minutes today, visitors to Cloudflare sites received 502 errors caused by a massive spike in CPU utilization on our network. (...) This was not an attack (as some have speculated)"

「此次服務中斷，是在日常佈署新規則到 Cloudflare Web Application Firewall 時，某一錯誤設定的規則造成。

這些新規則加強了對 (用來攻擊的) inline JavaScript 的阻擋。」(抱歉這句我怎麼翻都不順 XDD)

「不幸的是， 其中一個包含了正則表達式的規則，讓我們全世界的機器 CPU 使用量飆升到了 100%」

"The cause of this outage was deployment of a single misconfigured rule within the Cloudflare Web Application Firewall (WAF) during a routine deployment of new Cloudflare WAF Managed rules.

The intent of these new rules was to improve the blocking of inline JavaScript that is used in attacks."

"Unfortunately, one of these rules contained a regular expression that caused CPU to spike to 100% on our machines worldwide."

底下的留言：「來嘛讓我們看看你的正則表達式」

其實我也很好奇...到底什麼表達式可以讓 CPU 往上衝

The intent of these new rules was to improve the blocking of inline JavaScript that is used in attacks."

新增這些新規則的原意是用來阻擋通常被拿來做為攻擊用的 inline JS

這樣有比較順嗎？
