🧠 How it Works

⏱ 1. Scheduled Monitoring
A Schedule Trigger runs the workflow every 5 minutes. It reads the list of URLs from the Google Sheet and loops through each one.

🌍 2. Website Health Check
Each website is pinged to check if it’s online.

🔴 3. If Website is Down:
It verifies if a downtime record already exists.
If not, it:
Adds a new row in the Google Sheet with the timestamp.
Sends notifications via:
📧 Email
💬 Slack
📲 Telegram
📞 Voice Call via Vapi

🟢 4. If Website is Back Up:
It fetches the matching downtime record.
Updates the sheet with:
✅ Uptime timestamp
⏱ Total downtime duration
Sends recovery notifications via:
📧 Email
💬 Slack
📲 Telegram
(No phone call is made for uptime.)
