They wrote a really nice postmortem, analyzing, explaining the problem, and a linear time fix: http://stackstatus.net/post/147710624694/outage-postmortem-july-20-2016 I see quadratic time regular expressions all the time, and there have been multiple submitted that I haven’t posted just because they’re so common. This one is noteworthy because of the scale of impact it had. As Rob Pike points out, linking to Russ Cox’s excellent post these bugs are all the more tragic for being utterly ...| Accidentally Quadratic
Sanitizing input (as in trying to remove a subset of user input so that the remaining parts become “safe”) is hard to get right in itself. However, many developers doom their protection in the first place by choosing the wrong tool to get it done, in this case, regular expressions (regex for short).
