Vinny,
Thanks -- got the screenshot. Short version is:
69.39.160.194 --> 74.95.232.29
8. 68.85.245.150 0.0% 1735 45.0 48.9 44.9 175.1 16.2 (Bearcreek)
9. 68.85.245.154 76.5% 1735 55.5 57.9 50.3 164.3 14.3 (Royalton)
10. 68.85.245.206 77.0% 1735 55.0 59.0 51.5 170.2 16.3 (Bisbee)
...and similar loss all the way to destination...
74.95.232.29 --> 69.39.160.194
5. 68.85.245.205 0.0% (Royalton)
6. 68.85.245.153 0.0% (Bearcreek)
7. 68.84.94.137 0.0% (Dallas)
8. * * * 100.0%
9. 173.167.56.182 0.0% (per ARIN, Comcast Business netblock)
10. * * * 100.0%
11. * * * 100.0%
...where the destination is eventually reachable but there is very high
packet loss throughout all subsequent hops...
Agreed: to me this looks like something happened within the Comcast
network within Texas. It may have been as simple as circuit issues or
a router rebooting or experiencing issues "briefly".
If this is business-class service, you might be able to reach out to
whoever your sales/support rep is and try to get an answer.
Alternately, the only choices I see are to ask on either the Comcast HSI
(publicly viewable) or Comcast Direct (customer-to-Comcast only) forums
over on DSLR/BBR, respectively:
http://www.dslreports.com/forum/comcast
https://secure.dslreports.com/forum/comcastdirect
Ren Provo might have some ideas or insights, if she's lurking... :-)

It now goes direct from Greenspoint to Baytown. I was watching the routes change on Comcast's network. We aren't seeing an issue anymore. I was just wondering if anyone knew the cause. I'm suspecting maybe a large pipe was lost between Greenspoint and Baystown and the new path couldn't support the traffic load, but I'm just speculating. I wish I had an mtr from Comcast back to us, but alas I'm working with end users second hand on Windows when I asked for the information.
