Netflix issue ONLY on Apple TVs

Question

Here's the scenario:
I have 3 Apple TVs around my house. 2 are wired ethernet, 1 is WiFi connected. All are version 3 Apple TVs. Each and every one of these devices has an issue STARTING any stream of content from Netflix. The devices have no problem getting to Netflix to load the selection grids, the informational pages, etc. Only when I try to start a program/movie is there an issue. There will be a loading duration of between 45 seconds and 1 minute on EVERY program loaded from EVERY Apple TV in my house. Once getting past this long loading phase, the content streams in its highest quality flawlessly. If this is a series, the next episode load will take a very long time to load as well, although it is shorter than the initial load.
To validate, I have attempted to load Netflix content from laptops, both wired and WiFi, a Mac Mini, wired, and multiple tablet and phone devices. The ONLY devices showing this behavior are the Apple TVs. ALL OTHER devices load the content and stream perfectly fine, with the content starting to stream within 5 - 10 seconds.
I have written a couple of scripts to test network speed across my ISP at intervals throughout the day where heavy bandwidth congestion levels would be at their highest. This has yielded nothing interesting. My network access is rock solid to multiple data centers around the US with bandwidth averaging around 60Mb/10Mb.
There is nothing sub par in my home network. There are no consumer grade devices anywhere other than the cable modem, but if this were the problem, I would be seeing the same issues on every device, not just the Apple TVs. WiFi is canvassing my entire property via Ubiquiti APs. The entire WiFi network has been designed using the same Tamosoft Site Survey software that I use to layout all of my corporate locations. My core switch tying everything together is an Adtran 1544. All cabling is pretty much all hand built CAT6/5e.
I run a pretty large corporate network in my day job, so I'd like to think that I somewhat know what I'm doing with designing networks, measuring their performance, and troubleshooting congestion and other issues. These little black boxes are exactly that however; black boxes that should just work, which they do, for everything other than starting a Netflix stream efficiently.
This has all seemed to start happening within the past couple of months. Anyone else seeing this oddity with their Apple TVs and Netflix?

Thank god I'm not the only one!! 
I've had this issue for a few months now. EVERYTHING works on the Apple TV BUT Netflix.  Now its taking forever to even load the Netflix app on the ATV3.  It says Accessing Netflix for a good 45-60 seconds when you select the icon. Once you get a show going it streams just fine in full HD so its clearly not a signal issue.  Switching from one episode to the next takes forever as well.  I also have a PS4, iPad, Mac Mini and 2 iPhones on the same network and Netflix streams flawless.  Hulu, iTunes and everything else on the ATV3 work perfectly.  I don't get it.
I have completely reset everything....ATV3 and router to no avail.
I called Apple Support a couple months ago and the dude told me it was Netflix servers fault.  He said they use different servers for different devices.  So basically he thought the Netflix servers that feed ATV devices were screwing up.  Pretty sure he had no idea what he was talking about and just wanted to shift blame.
I personally feel like its the Netflix app within the ATV its self.  I don't think it really has anything to do with the network or signal at all.  I guess i'm pretty well screwed because now its out of warranty.
