I would like to know if it is possible to redirect all traffic from my url ( mydomain.com ) to zeit.co and from there redirect wp.mydomain.com to my content server.
That way I could edit the contents using the Wordpress dashboard, going to wp.myadomain.com
I was also looking at this. There is a way to do it with Cnames on your registrar and not using zeit name servers. then you can redirect wp.mydomain.com from your registrar using A record to your wordpress install. I havent tried it though. Let me know if it works. I might use it myself.
Also just found this
Looks like the method of using TXT record to direct the main domain to zeit and then using A records with your registrar to redirect your subdomain wordpress install to a regular host should work perfectly.
By the way, you don’t need to change your DNS’s to use Zeit. You can add a CNAME record pointing to
alias.zeit.co to any domain that you want to use with them.
