DigitalOcean Uptime is a monitoring service that checks the health of any URL or IP address. Use Uptime to monitor the latency, uptime, and SSL certificates of any website or host, and receive email or Slack alerts at thresholds you choose.
Each Uptime check costs $1.00 per month, billed in hourly increments. There is no additional cost for alerts.
Your invoice is credited with 1 free Uptime check per month. This appears as 672 hours of credit and is split between multiple checks if none of your Uptime checks are active for the full month.
