Web Servers List (Google Sheets)  \nFetches a list of server hostnames or IP addresses from a Google Sheet.  \nEach row is treated as one server. This makes server management easy — no need to edit the workflow to add/remove servers.\n\n🌐 3. Server Alive Check (HTTP) \nSends an HTTP GET request to each server (e.g., {{ $env.WEBHOOK_URL }}  \nIf the request fails, the error path is triggered.  \n\n📝 4. Web Server Alive Log (Google Sheets)  \nLogs successful server checks into a separate Sheet with a timestamp.\nThis log helps track uptime history, verify server health, and generate availability reports.\n\n🚨📧 5. Server Down Notification (Gmail)  \nSends an alert email if a server does not respond or returns an error.  \nIncludes the server address and the timestamp of failure.\n\n📝 6. Web Server Down Log (Google Sheets)\nLogs the failed server checks into another Sheet with a timestamp.  \nUseful for uptime reporting, debugging, and audit tracking.\n"
