An automated Website Uptime Monitoring

An automated Website Uptime Monitoring & Alerting pipeline in n8n that regularly tests site responsiveness, double-checks downtime to prevent false alarms, and dispatches instant email/Telegram alerts upon failure.

Core Workflow Steps

Schedule & Configuration: Triggers at scheduled intervals, pulling website URLs along with Telegram Chat ID and Email notification credentials from the configuration node.

Initial Site Testing: Splits the list of URLs and performs HTTP requests (Perform Site Test) to evaluate whether each site is online (UP) or offline (DOWN).

Router & Delay Retry: Routes site statuses; if a site appears DOWN, it pauses (Wait) and re-tests the URL (Perform Site Test1) to double-check and prevent false downtime alerts.

Alert Notification: If the website remains unresponsive after the retry step, the router triggers the Send email (or Telegram) node to send an instant alert.👍 🎉
