I really want to know the regexp and corresponding input(s) which killed the internet now :) Was it just aaaaaaaaaaaah?

https://swtch.com/~rsc/regexp/regexp1.html



Probably something mundane like ^[\s\u200c]+|[\s\u200c]+$

That's the one that took down Stack Overflow a few years ago https://stackstatus.net/post/147710624694/outage-postmortem-...


It reminds me of an old joke. I decided to solve a software problem with regular expressions and now I have two problems.


I'm assuming it's something pretty embarrassing if it's not in the post mortem.


The first sentence here is "This is a short placeholder blog and will be replaced with a full post-mortem...".

I'd bet big money that they do include it.


Look forward to the full post-mortem
