Setting up a GNU Mailman mailing-list with the 'reply-to-all' setting still set to on (as per the defaults).
It was intended to be a distribution list.
The list had 8,000 recipients.
.
I found out what an ohnosecond is, as the blood chilled a little in my veins.
Turned out not too bad, 6 innocuous replies were sent out to everyone. It was fully open for about 25 minutes before I set 'reply-to-all' to off. Could have been much worse.
Will never ever forget to do that with a mailing-list again.
I broke the home page of a big tech (FAANG) company.
I added a call to an API created by another team. I did an initial test with 2% of production traffic + 50% of employee traffic, and it worked fine. After a day or two, I rolled out to 100% of users, and it broke the home page. It was broken for around 3 minutes until the deployment oncall found the killswitch I put in the code and turned it off. They noticed the issue quicker than I did.
What I didn't realise was that only some of the methods of this class had Memcache caching. The method I was calling did not. It turns out it was running a database query on a DB with a single shard and only 4 replicas, that wasn't designed for production traffic. As soon as my code rolled out to 100% of users. the DBs immediately fell over from tens of thousands of simultaneous connections.
Always use feature flags for risky work! It would have been broken for a lot longer if I didn't add one and they had to re-deploy the site. The site was continuously pushed all day, but building and deploying could take 45+ mins.

This reminds me of the old saying: everyone has a test environment. Some people are lucky enough to have a separate production environment, too.
I once pushed a git commit with youtube link as the commit message. Nothing terrible, some completely random video. Still, it looked really weird in the commit history. Turns out you can edit this if you have access to the server and I did have access to the server.
One time in the same company I found a random youtube link in the middle of a java class. Yes, it was still compiling. No I didn't commit it.
Now that i think about my first job was fucking wild.
My buddy was in a forklift taking some stock down and i was spotting, basically just hanging out and making sure no one got in the way. A few minutes after the normal time it'd take he thinks something is wrong and calls me to take a look (from afar) to see how fucked we are; the answer was very, the pallet was barely holding together at all, but i couldn't see a damn thing from my position. Before i could get back to spotting we heard a loud crack and the world went still, i imagine for much longer by him, and not a second later we had hundreds of pounds of foul smelling mulch everywhere.
I had a lot more there too; babysitting an old man that looked on the verge of death with no management anywhere to be found, moving hundreds of pounds at a time by hand, dealing with the best conspiracy theorist ever.
I've been bored everywhere else I've ever worked.
There's something about physical labor jobs that result in everybody having one story about babysitting somebody who is actively dying
