At AA6E, we are using the Comcast "Xfinity" "blast" service, which originally provided 50 Mb/s download, but now seems to have been quietly upgraded to ~100 Mb/s. Oh, we seem to have IPv6 service now, too. Effectively using that in my home network will be a challenge. (One that I don't need at this time!)

The list price for this service is pretty steep IMO ($60/mo), but a slower service is not much cheaper.
