Question

描述您在生产事故中的角色。

Accepted Answer

他们想看到您在压力下**保持冷静、遵循流程、不互相指责** — 首先恢复服务，其次诊断问题，第三防止再次发生。使用 **STAR** 方法。

## 如何处理

```text
INCIDENT ORDER
1. Stabilize — stop the bleeding (rollback, failover, mitigate)
2. Communicate — keep stakeholders updated on a clear channel
3. Diagnose — root cause once it's stable, not during
4. Prevent — a blameless post-mortem with action items
```

## 实际例子

```text
S: A deploy caused checkout errors for ~15% of users.
T: I was on call and had to restore service fast.
A: I rolled back the deploy first (service recovered in minutes), posted updates
   every 10 minutes, then traced the cause to an unhandled null from a new API
   field. I added a guard and a contract test.
R: Downtime stayed under 20 minutes. The post-mortem added the missing test to
   CI so it can't recur.
```

## 好的与弱的表现

```text
✓ Mitigate first, communicate, blameless follow-up
✗ Debugging live while users are down
✗ Blaming the person who deployed
```

## 为什么这很重要

事故考验的是心态 — 当系统故障时，团队需要的是稳定的手，而不是恐慌。

无责怪的方法让人们坦诚对待问题根源，这是防止问题再次发生的唯一途径。

你如何处理最困难的时刻比你如何处理顺利的日子更能体现你的职业水平。
