Sub-domains on CloudFlare are marked with an orange cloud. Sub-domains not on CloudFlare are marked with a gray cloud.

The CloudFlare network can only proxy web traffic over port 80 and 443. The following sub-domains should be marked with a gray cloud to prevent performance issues:




mail and webmail


nameservers (NS1, NS2)

secure* (unless you enable CloudFlare SSL)
