The website(s) design is for a company active in 3 different areas.
As an example lets use the following structure:
www.example.com [sub1.example.com] [sub2.example.com] [sub3.example.com]
sub3.example.com are ready to go live but
www.example.com really isn't and send a 503 HTTP error code. I would like to know if this situation will affect the traffic and ranking of the subdomains ready to go live?
Is it preferable to wait and go live with the main domain? Or there is nothing to "fear" and one doesn't affect the other?
