  • When a Junior Triggers a Production Incident: What’s the Right Way to Respond Without Making Things Worse?

    The first time I broke production, I honestly thought I was done for. The bug itself wasn’t huge, but the panic that followed definitely was. I pushed a quick fix without validating the state properly and ended up creating a second issue… which was way harder to unwind. That moment taught me something uncomfortable: during incidents, juniors aren’t judged only on what broke — they’re judged on how they behave while things are breaking.

    But staying calm is not natural when alerts are firing and everyone is asking “What happened?” at the same time. It feels like the whole system is collapsing on your shoulders.

    For anyone who has dealt with this:
    How do you keep your head steady enough to avoid second-impact mistakes? What does a “responsible” response from a junior actually look like to senior engineers? And is there a simple sequence you followed — something like diagnosis → verification → communication → action — that helps prevent panic patches or unnecessary rollbacks?

    Would love real experiences. This topic doesn’t get discussed honestly enough.

    I’ve been on both sides — the junior who panicked and the senior watching someone panic — and the difference is night and day. Most juniors think seniors want instant action. That’s not true. Seniors want controlled action. When something breaks, the worst thing you can do is start clicking buttons like you’re disarming a bomb.

    What saved me later in my career was forcing a 3-step pattern:
    (1) Freeze for 30–60 seconds. Literally just breathe and look at logs/state.
    (2) Say out loud what you’re seeing. Even if you’re unsure.
    (3) Avoid writes until someone confirms the diagnosis.

    The funny thing is: this looks “slow” when you’re new, but seniors see it as maturity. If you communicate early, validate assumptions, and avoid speculative fixes, you already look more experienced than 80% of juniors who panic-patch their way into doubling the blast radius.

    My worst production scare happened during a liquidity-pool upgrade. A junior thought the pool was stuck, so they instantly suggested redeploying the contract. Turned out the keeper script had stalled, nothing on-chain was actually broken. That was a moment where I realised most incidents aren’t “incidents” — they’re mismatches between symptoms and root cause.

    So now whenever something looks off, I follow this simple rule:
    “Validate the symptom before hunting the cure.”

    Open Etherscan, check storage slots, run a read-only call, replay the last tx. If something touches state, I double-check twice. I don’t care if a founder is standing behind me breathing heavily — I trust the chain more than vibes.

    Juniors think seniors magically “know things.” We don’t. We just don’t touch anything writable until we fully understand the blast radius. That alone prevents half the accidental disasters.

    The same pattern repeats across AOB: juniors rarely get judged for the first mistake — they get judged for the second mistake made in panic. If you want to build stronger instincts around debugging, communication, and avoiding second-impact issues, these AOB threads go much deeper into the same real-world patterns:

    All three threads reinforce the same lesson: calm, verification-first thinking beats speed during incidents — especially in Web3 where writes cannot be rolled back.

    I mentor juniors during audits, and I’ll tell you the pattern I see almost every month: the real damage doesn’t come from the first mistake — it comes from the second mistake made under fear. In our audit logs, around 35–45% of escalated issues happen because someone tried to “fix fast” without understanding contract state, especially during governance or token-release flows.

    A few behaviours instantly raise trust in juniors:

    Asking for a second pair of eyes before touching state

    Calling out assumptions early (“I think the issue is off-chain, here’s why…”)

    Documenting the blast radius out loud

    Running read-only traces before proposing a write

    And here’s something juniors don’t realise: seniors prefer a junior who slows things down for 2 minutes over one who ships a hotfix in 20 seconds. Web2 allows fast rollbacks. Web3 doesn’t. One wrong write can freeze funds or corrupt state permanently. Calm beats clever every single time.
