I wonder if you are able to talk a bit about the development of the Lua-based WAF. I imagine the possible unbounded performance of feeding requests into PCRE must have occurred to you or others at the time - or at least, long before this outage.

I don't mean this as some sort of lame 'lol shoulda known better' dunk - stories about technical organizations' decision-making and tradeoff-handling are just more interesting than the details of how regexes typed in a control panel grow up to become Jira tickets.
