Comcast Enterprise Fiber Slow Connection Problem from TW Telecom

[Zachary Frederick <zcfrederick () gmail com>]

We have been having a problem receiving software releases from our developer. The releases are typically around 1G in 
size. The developer’s connection is a 100m metro fiber with TW Telecom,  our connection is a 25m Comcast Enterprise 
Fiber.

Our traffic graphs show very little utilization of our connection. Typically on average we are at about 7 meg 
utilization of our 25.

Every other partner that shares in our software development that receives the software releases can receive the updates 
3-4 times faster than we can.

Typically we receive the releases at about 3mbps.

I have tried contacting Comcast Enterprise Tech support, however I’ve been told that if I run a speed test from my 
connection and the test runs at the speed we are paying for, there is very little they are willing to look into.

Can anyone check on the Comcast Routers on the Tracert below, or is there anything that can be throttling this 
connection between the two connections?

Also, our firewall and connection is able to run at the full 25. We have no throttling or QOS set to prevent a good 
connection to our developer. For example, we can run a multi-threaded upload, in the middle of the night, to Amazon 
Glacier storage and completely saturate our connection when doing so. The firewall and connection is able to handle our 
full bandwidth capacity during that backup.

If there is any other information I can provide to help track this problem down, please let me know.

Thanks in advance, everyone!
