ATT Routing Issue (other post deleted?)

It looks like my last post may have been deleted, I cannot find it anywhere.

I seem to be having latency issues, specifically regarding Steam and CS:GO.  I used to be able to connect to official Valve servers and get anywhere from 3MS to 20MS ping.  However, about 2 months ago, I cannot get connect to anything under 50MS.  I get prompted with a warning in the game letting me know it cannot find any servers.  I've spoken to ATT support on the phone and was told to contact Steam.  Steam said it's not their issue.  

I've tested with multiple devices and get the same error.  I had a local friends who are on WOW and Xfinity also run a tracert.  They average about a ping in the 20's and only go to 8 hops.  They do not even hit the Telia server.  

Can someone help me find a resolution to this?  Here is what I wrote Steam:

I have ATT Fiber (Chicago) 1GB internet. I used to be able to connect to MM offical servers and my ping would be anywhere from 3MS to about 20MS. About 2 months ago, something changed and now I cannot find a game under 50MS. The game shows me the unable to find server with ping error. The last game I connected to is a Chicago based server. I obtained the IP address via WireShark.

I've talked to ATT tech support and they said to start with contact Steam Support. As you can see, ATT hands traffic off after hop 6 with low latency. Hops 7 and 8 are very high and 9 times out.

Can someone please tell me what I need to do to fix this?
