How to configure fastly with subdomain


We have a running live site (, we are planning to migrate to another server ( While configuring fastly to the test domain, it complains about “Domain is already taken by another customer”.

what is the right way to test the fastly in “test domain”?



Hello Bilalusean,

If the domain in question is already taken/used by another service not tied to your account it will throw the error you saw. I recommend opening a support ticket as long as you can validate domain ownership, support should be able to delegate a specific domain for the service in question.
