In a nutshell recap,I have not been able to get a good checksum(8-10
tries over several days) for Ubuntu Distro server with laptop wired to
router, from my home location through the ISP 5GHz wireless internet
connect.
While using that same laptop,same server address request, similarly
wired connect at ISP office resulted in good checksum.
Santa Fe baking Co.same laptop and reflector wireless 801.11 connect,
good checksum.
Your request MTR,I am leaving the search for the Distro address,unless
you feels it is still relevant considering the nutshell description:
www.ubuntu.com/desktop/get-ubuntu/download
"No whois server is known for this kind of object"
