# Northwind Health: Q3 platform review

Prepared for the **operations committee**. Figures are *placeholders* for this example.

## Summary

- Uptime held at the target for the quarter
- Two incidents, both under 30 minutes
  - INC-101: login latency
  - INC-102: delayed reminder emails
- [x] Migrate reminders to the new queue
- [ ] Retire the old scheduler

> Decision needed: approve the scheduler retirement for October.

## How a reminder is sent

```mermaid

    Sched([Scheduler]) -->|enqueue| Q{{Reminder queue}}
    Q --> W[Worker]
    W -->|SMTP| Mail[(Mail relay)]
```

The worker retries with this rule:

```python
def backoff(attempt):
    return min(2 ** attempt, 300)  # seconds, capped at 5 minutes
```
