Using Cloudflare

If you use Cloudflare for your website, Cloudflare is always between the visitor and your website. This also applies to the monitoring by DownNotifier. Generally, this works without any issues, but there are a few things to keep in mind.

Undetected Downtime

Cloudflare can cache pages, meaning it might serve a cached version of your page when your server is down. Therefore, we recommend monitoring without caching. This can be done in two ways:

1. Set up a second monitor directly on your server's IP address.
2. Disable caching for DownNotifier in Cloudflare. Here's how:
   • In Cloudflare, navigate to the relevant website.
   • Go to Caching - Cache Rules.
   • Choose Create Rule.
   • Enter a name (e.g., DownNotifier) and select Custom filter expression.
   • Choose Field: User Agent, Operator: Contains, Value: downnotifier.com monitoring.
   • Then select "Bypass cache."
   • Click Deploy.

Access for DownNotifier.com

If you have additional security measures (such as country blocks) in place, you might be blocking DownNotifier. You can resolve this as follows:

• In Cloudflare, navigate to the relevant website.
• Go to Security - WAF - Custom Rules.
• Choose Create Rule.
• Enter a name (e.g., DownNotifier).
• Choose Field: User Agent, Operator: Contains, Value: downnotifier.com monitoring.
• Under Choose Action, select Skip.
• Check all components under "WAF components to skip," including those under More.
• Click Deploy.
