Xfinite is blocking just about any website that uses http://myshopify.com (22.214.171.124) as their host. For example http://wildforkfoods.com. If I disconnect from wifi on my phone and use the AT&T network I can get to the site. If I connect to wifi and use xfinity network, it fails. This is happening with other websites and the one thing they have in common is that they are hosted by http://myshopify.com.
