Gigapower - Youtube Throttling #2

Since the last topic was closed, I'll make another one. That topic was created in January with a slew of "band aids" but nothing in that topic is concrete besides AT&T's issue with Youtube or the trip in between. It's almost October and I still see this issue pop up quite a bit, fellow neighbors getting Gigapower and asking me "does Youtube load slow for you?". I have had Gigapower 1Gb since May in a new neighborhood in Fort Worth, Texas and this issue has been a persistent pest since day 1. Before I had Frontier 150/150 and not once had a single issue with service in terms of speed or responsiveness of services/websites. All of the bandaids listed in the previous thread are just that, bandaids, a temporary work around for the problem that has never been resolved between AT&T and Google. 

• Change DNS (Google or otherwise)
• DIsable IPV6
• Reset network equipment
• Disable QUIC Protocol (this is made moot when other browsers act the same way)
• Passthrough to new router
• Port forwarding / DMZ

These are all things that may or may not temporarily fix this issue and I hate that the other thread was closed based on an assumption that Chrome's QUIC was the actual culprit, it's not. Matter a fact, I've had that disabled since they introduced it in beta builds. I still have this issue with Youtube on ANY device in my house besides mobile (for the reasons outlined in the other thread, the path from AT&T to Google and back is different for the mobile app). Since people are successfully bypassing this issue with a VPN it proves that it's not client side period. I may be talking to a brick wall here but the other thread had a guy that allegedly was communicating with NOC people. The only thing that I haven't seen suggested on a back end side is, has anybody looked into the possibility that it could be Akamai caching causing the slowdown? Has anybody tried to see if Youtube traffic is flowing through their traffic/caching service? Can the NOC guys confirm whether or not we are getting a direct link or flowing through a service such as Akamai? As a very heavy user I can pretty much attest that AT&T is not throttling us. With speeds like these we are limited to the speed of the other end and latency/distance. Thing is, the traces posted in the other thread had timeouts and we cannot be certain where the hop was that timed out. Maybe somebody can provide more feedback but I'm almost certain AT&T is flowing through somewhere that is a considerate bottleneck for Youtube. Youtube is the only issue I've had so far.

Equipment I'm using:
Completely bypassed BGW210-700

Ubiquiti USG 3

Ubiquiti Unifi 16XG
Ubiquiti Unifi 16port POE switch

Ubiquiti AC-PRO-AP

Assortment of other Ubiquiti switches etc

ALL CAT6a FTP cabling

Here is a picture of my traffic for this month up and down, and a picture showing about 80GB of Akamai and without digging with Wireshark I have no idea what sites are flowing through it.
