I got a mini problem. Few Internet Providers in my region blocks the access to WordPress blogs, including mine. They do not block wordpress.com, but all subdomains, for instance abc.wordpress.com, including those with a custom domain.
I wonder if I can edit Custom DNS Records so that I can bypass this.
FYI, they also block the access to Blospot blogs. However, blog owners can edit their DNS records (maybe they switch to ghs.google.com or something), so blog viewers can still read their posts.
