I found something on the help page, which may explain this, as when I set it to “Medium” it seems resolved. but I would like to hear about your past experience?
What Security Level should I select?
The Security Level you choose will determine which visitors will be presented with a challenge page. We recommend starting out at Medium.
Essentially off: Challenges only the most grievous offenders
Low: Challenges only the most threatening visitors
Medium: Challenges both moderate threat visitors and the most threatening visitors
High: Challenges all visitors that have exhibited threatening behavior within the last 14 days
I’m Under Attack!: Should only be used if your website is under a DDoS attack
- Visitors will receive an interstitial page while we analyze their traffic and behavior to make sure they are a legitimate human visitor trying to access your website
Note: I’m Under Attack! may affect some actions on your domain. For example, it may block access to your API. You can set a custom security level for any part of your domain using Page Rules.
