Geo Balancer option disables content distribution in certain regions. It can increase the Cache Hit Ratio if your primary audience is located in one or maybe two-three regions.
By default, if a user from disabled region reaches for the content, the request is transferred to the CDN servers from Europe. So, Europe can't be disabled.
How to enable the option
Contact us via chat or email. The option will be set up to all the resources in your account.
Then if you're using personal CNAME change your DNS settings. It should look like CNAME IN [client_yourID].gcdn.co.
For example, CNAME IN client111.gcdn.co
If your CNAME is in our zone, we set up DNS from our side.
To disable option also contact us.
