There are two kinds of developers in this world:
1️⃣ Those who’ve deployed on Friday.
2️⃣ Those who will never do it again.
If you’re still considering pushing that “tiny” hotfix at 5:47 PM on a Friday, let’s pause for a moment… breathe… and walk through why this is basically the tech equivalent of summoning a digital demon.
1. Friday Deploys Aren’t Deploys — They’re Dice Rolls
You think you’re shipping a small change.
But your code knows it’s Friday.
And it will betray you.
Memory leaks magically appear.
APIs suddenly forget they exist.
The database decides to take an early weekend.
There’s a reason every senior engineer screams internally when they hear:
“Let’s just deploy real quick before we go home.”
2. Your Support Team Doesn’t Want a Surprise Party
On Friday, everyone has one mission:
escape the building before another meeting appears.
But deploy on Friday… and congratulations:
You’ve just invited the entire team to a midnight debugging party.
Pizza: cold.
Coffee: burnt.
Colleagues: angry.
Production: on fire.
No one wants to start their weekend with error logs as their reading material.
3. Nothing Breaks Faster Than a ‘Small Patch’
The deadliest words in engineering:
“It’s just a quick fix.”
Wrong.
This “quick fix” usually touches:
✔ authentication
✔ caching
✔ billing
✔ real-time notifications
✔ the secret code written in 2014 by a dev no one remembers
Deploy that on Friday and you won’t see sunlight until Monday.
4. Murphy’s Law Loves Fridays
If something can go wrong…
…it will go wrong after everyone leaves Slack.
You won’t reach backend, because he’s in the sauna.
You won’t reach QA, because she’s on a plane.
You won’t reach DevOps, because he’s hiking somewhere with zero signal.
And you definitely won’t reach design — because designers don’t answer messages on Fridays on principle.
5. Your Future Self Will Hate You
Imagine Monday morning:
You: “Why is production down?”
Team: “You deployed on Friday.”
You: “Oh.”
Team: “Oh.”
Monday ruined.
Week ruined.
Reputation ruined.
And worst of all — you replay the moment you hit “Deploy” like a horror movie flashback.
So When Should You Deploy?
✨ Monday to Thursday.
✨ Early in the day.
✨ When your whole team is online, caffeinated and emotionally stable.
And if your team never feels stable?
Well, that’s a separate issue — one that modern IT consulting and outsourced CTO services are literally built to fix. (Нативная вставка будет здесь позже.)
Final Rule of Engineering:
If you value your weekend, your sanity, and your production environment…
Deploying on Friday? Don’t.
