Monitoring Transparency

Monitoring Locations and Source IPs

Use this list to allow-list monitoring traffic in firewalls, WAFs, and network policies so checks remain accurate.

Important before enabling checks

Please verify that the IP addresses or ranges listed below are allow-listed in your infrastructure. If they are blocked, monitoring requests may be flagged as bot traffic and rejected.

Quick checklist

  • Add the IP addresses to your firewall, WAF, or CDN allow-list.
  • Ensure security rules do not classify monitoring requests as bots.
  • Run a test check after changes and validate the result.

Why this matters

If source IPs are blocked by your infrastructure, checks may fail although your service is healthy. Allow-listing these IPs reduces false negatives.
