Slow network speed to one location

I have a strange issue and I am trying to figure out the best way to resolve it.  We have multiple web servers at the company that I manage IT for and I often are administering computers using remote desktop via VPN.

In all cases whether remote desktop or just downloading files I notice the connection being very sluggish.  I have Comcast internet at home and are consistently getting 60 Mb/sec down and 20 Mb/sec up.  When downloading files from other sites I often get 2+ MB download speed.  When downloading files from our company's web server I am getting 100-150 Kb/sec.  The internet connection at our company is dedicated fiber 100Mb/sec symmetrical connection.

Now the odd thing is that if I join to a 3rd party VPN service but still using my home internet connection, my download speeds from my company go to 2+ Mb/sec. which is what I would expect.  I also have 2+ Mb/sec connection to my office if I use a LTE card or something like that.

It seems like maybe there is an issue in the route that Comcast is maybe taking?  Anyone have any suggestions on how to diagnose this issue?

Does doing a TRACERT to your company with the different connections show anything interesting?

Comcast definitely is having a problem with the route it is picking.
- #2 is probably one of their internal servers timing out.
- who knows where #9 is.
- #'s 10,12, and 13 are bogging down the flow.

Maybe somebody that is using Comcast will have a better idea, but I would do a few more tracerts at different times, then when you have some time to kill, call Cc and and tell them what you are seeing, and ask if they can maybe "shuffle" things around a little.

I'm now officially "over my head", but maybe Deleting and Redoing the VPN at home, will get you a better route.
Just a thought...
