Beginning today, all GitHub Pages sites are moving to a new, dedicated
domain: github.io. This is a security measure aimed at removing potential
vectors for cross domain attacks targeting the main github.com session as well
as vectors for phishing attacks relying on the presence of the “github.com”
domain to build a false sense of trust in malicious websites.
If you’ve configured a custom domain for your Pages site (“yoursite.com”
instead of “yoursite.github.com”) then you are not affected by this change
and may stop reading now.
If your Pages site was previously served from a username.github.com domain,
all traffic will be redirected to the new username.github.io location
indefinitely, so you won’t have to change any links. For example, newmerator.github.com now redirects to newmerator.github.io.
From this point on, any website hosted under the github.com domain may be
assumed to be an official GitHub product or service.
