If you are planning to use CloudFlare proxy, or already do, we recommend informing us about it. We need to make the neccessary adjustments to our infrastructure, so that real IP addresses appear in logs. We also need to adjust our monitoring accordingly.
Based on how CloudFlare works, it is necessary to transfer DNS records (change authoritative name servers) to CloudFlare, before enabling CloudFlare proxy. This is critical change to production environment and any mistake can lead to long DNS outage. If you are unsure about the whole process, please contact our technical support.
