Routing has absolutely nothing to do with DNS.
Unless you're using Cloudflare's new 1.1.1.1 service, whereupon you learn just how broken some routers are when they treat 1.1.1.1 as an internal resource, even though it's a non-reserved number or network. :-)
But that's not what we're talking about here. 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.
