Happened a few weeks ago but still awesome.

Me and a good friend have a website together but we don't monitor it too much.
He studied with me in the same class but went towards frontend/apps where I chose backend/servers/security. He knows how to do basic Linux stuff but that's about it.

We were at a party when he noticed that our site was offline. Walked over to me (because I manage the server) to notify me so I could look into it said I'd look into it (phone):
*visits site: nothing*
*online dig tool: got the server ip*
*remembered this one didn't have pubkey authentication - after three passwords attempts I'm in*

"service apache2 status"
*service doesn't exist*
*right, migrated this one from Apache to nginx....*
"history"
*ah, an nginx restart probably suffices...*
"service nginx restart"

BAM, site is reachable again.

*god damnit, lets encrypt cert expired...*
"history"
*sees command with certbot and our domain both in one*
"!892"
*20 seconds later: success message*
*service nginx reload*

BAM, site works securely again.

"Yo mate, check the site again"

Mate: 😶 w-w-what? *checks site and his watch* you started less than two minutes ago...?
Me: yeah..?
Mate: 😶 now this is why YOU manage our server and I don't 😐

His face was fucking gold. It wasn't that difficult for me (I do this daily) but to him, I was a God at that moment.

Awesome moment 😊
