congestion/packet loss many times a day from 96.120.49.29

I'm located in Minnesota, and many times a day I can see the device 96.120.49.29 suddenly dropping packets and usually in same time a total loss of internet service happens for 3-4 minutes causing all my applications (mainly vpn with my company) to drop... This has been getting worst and worst in the last few months... causing a lot of time spent reconnecting/relogging in, losing work in progress, etc... I initially thought it was my gateway, but that hop doesn't drop anything at the time of those outages...

 

  Here is an example of a mtr going out during a normal period

 

Host Loss% Snt Last Avg Best Wrst StDev
1. 173-8-123-78-Minnesota.hfc.comcastbusi 0.0% 672 0.7 0.6 0.5 4.8 0.3
2. 96.120.49.29 0.0% 672 8.2 8.3 6.6 23.8 1.8
3. te-0-0-0-2-sur02.maplegrove.mn.minn.co 0.0% 672 9.1 9.1 6.9 29.7 2.4
4. be-15-ar01.roseville.mn.minn.comcast.n 0.0% 672 9.7 11.4 7.9 32.7 2.3
5. 4.68.71.61 0.0% 672 15.1 12.1 4.8 75.4 9.0
6. vl-5.car1.Detroit1.Level3.net 0.0% 672 23.7 61.1 22.4 442.5 67.2

 

and here is a quick capture of what it looks EVERY time we lose connectivity...

 

Host Loss% Snt Last Avg Best Wrst StDev

2. 96.120.49.29 24.2% 33 8.9 12.9 7.1 34.1 8.0
3. te-0-0-0-2-sur02.maplegrove.mn.minn.co 18.2% 33 8.7 15.4 7.7 36.1 9.6
4. be-15-ar01.roseville.mn.minn.comcast.n 42.4% 33 9.6 15.9 8.7 35.8 8.2
5. 4.68.71.61 51.5% 33 8.5 19.8 8.3 45.5 12.7
6. vl-5.car1.Detroit1.Level3.net 36.4% 33 23.1 28.9 23.1 48.5 8.1

 

It usually reaches high 80% loss... then goes back to the previous output...

 

Have you encountered the same issue ? this is reaching unbearable levels...

I setup a permanent monitoring (http://od.gaelm.fr/cgi-bin/smokeping.cgi?target=Comcast) , and here how it looks monitoring the first device, a few of those peaks disrupted my network connection so bad that it interrupted a conference call and disconnected my vpn client... 

 

I called support and was told they could send somebody to check my cabling... Can a cabling issue cause such inconsistent behavior where all is well so long then all hell break lose for a few minutes and comes back fine ??
