I was trying to host our new Technology council of Southern California blog on a sub-domain that’s managed by Verio.
I followed the instructions, but Verio doesn’t allowing mapping a CNAME to a domain that also redirects to a CNAME as I found out from this blog post.
Using IPtools, I learned that the subdomain.wordpress.com blog CNAME’s to lb.wordpress.com.
I updated the Verio settings to:
blog.tcosc.org. 86400 IN CNAME lb.wordpress.com.
and the sub-domain now works.
