+### Information for Hosting Providers
+
+If you're a hosting provider (like Vercel, Netlify, or similar platforms), please consider the following guidance regarding Sentry's Uptime Monitoring:
+
+Many organizations use Sentry to monitor the uptime of their websites and applications. When Sentry's monitoring IPs are blocked, it creates false outage alerts for all customers trying to monitor sites on your platform.
+
+**Recommended actions for hosting providers:**
+
+1. Allowlist Sentry's monitoring IP addresses in your platform's security rules
+2. Configure your firewall to recognize Sentry's monitoring user agent and IP ranges as legitimate traffic
+3. Ensure rate limiting policies do not inadvertently block Sentry's monitoring capabilities
+4. Consider implementing automatic updates of allowlisted IPs using our API endpoint
+
+By ensuring Sentry can properly monitor sites on your platform, you'll improve the reliability monitoring experience for all your customers who use Sentry.
