The video is about a Cloudflare outage caused by a poorly written regular expression.
The regular expression was part of a web application firewall rule designed to detect cross-site scripting attempts. The rule was supposed to match JavaScript keywords, suspicious characters, and strings with equal signs, which are potential indicators of malicious URL query strings. However, the regular expression was written in a way that caused it to match an unexpectedly large number of strings. This led to the web application firewall consuming 100% of CPU on all of Cloudflare's servers, which caused a global outage.
The video goes into detail about how the regular expression worked and why it was so inefficient. It also discusses the steps that Cloudflare took to fix the problem and prevent it from happening again.
Here are some of the key points from the video:
The regular expression used a non-capturing group, which caused it to match many more strings than it was intended to.
The regular expression used a dot star, which matches any character zero or more times. This can be very inefficient if the regular expression is not carefully written.
The regular expression used backtracking, which is a technique that can be very slow if the regular expression is not carefully written.
The video concludes with a warning about the dangers of using regular expressions without understanding how they work. It also suggests that people should use simpler tools, such as string contains, whenever possible.
