The domain 'blog.lacour.me' doesn't resolve for me:

Your name servers seem to be ns[1-5].he.net, and ns1.he.net doesn't know what blog.lacour.me is:

  > blog.lacour.me  
  Server:  ns1.he.net  
  Address:  216.218.130.2

  *** No address (A) records available for blog.lacour.me

Some of comcast's DNS resolvers must be confused. I get different results each time I make a query:

    $ dig @75.75.75.75  blog.lacour.me
    QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
    {{ no answer }}


    $ dig @75.75.75.75  blog.lacour.me
    QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 0
    blog.lacour.me.		75275	IN	CNAME	silvrback.herokuapp.com.
    silvrback.herokuapp.com. 156	IN	CNAME	us-east-1-a.route.herokuapp.com.
    us-east-1-a.route.herokuapp.com. 30 IN	A	23.23.208.103

It's not using an A record, it's using a CNAME:

  host blog.lacour.me
  blog.lacour.me is an alias for silvrback.herokuapp.com.
  silvrback.herokuapp.com is an alias for us-east-1-a.route.herokuapp.com.
  us-east-1-a.route.herokuapp.com has address 54.83.3.141

The CNAME doesn't resolve for me either. I can't see whatever this is.
