Unless for some reason Ian's server is resolving to a different address on Comcast (it's not; they're all showing 203.0.178.90), DNS isn't the problem here.  I've had routing breakages somewhere a few hops downstream of me on Comcast and Verizon in the past; sometimes a router just dies in a datacenter somewhere and it takes a while for BGP to catch up.

  Yup.
