You are helping me build the following AI agent workflow.

## Goal
Server Uptime Monitor & Alert System: Pings servers from a Google Sheet every minute, logging status to Alive/Down sheets and emailing alerts on failure.

## Specification
- What it does: Get instant email alerts when your servers go down so you can fix issues immediately. The system pings every server listed in your Google Sheet each minute, logging active status to an 'Alive' sheet and recording failures with timestamps in a 'Down' sheet. You receive detailed notifications containing the specific server address whenever a failure occurs.
- Trigger: On a schedule (Scheduled · every minute)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Google Sheets: Store server list and uptime logs
  - HTTP Request: Ping servers to check status
  - Gmail: Send downtime alerts

## Known pitfalls, handle each one explicitly in your implementation
1. URLFetchApp does not follow redirects by default in all configurations, so explicitly handle HTTP status codes like 301 and 302 to ensure accurate uptime tracking.
2. Gmail quotas reset daily but are strict, so implement a cooldown mechanism to prevent sending more than fifty emails per day for the same alert type.

## Reference implementation
https://n8n.io/workflows/3880 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
