Re: [AFMUG] FW: Fast.com (Netflix) tests significantly slower than EVERYTHING ELSE

[Robert Andrews]

We had a customer with a smart TV.. (Samsung) that was having tons of 
problems with Netflix...  Had them put in a USB ( chromecast?) dongle to 
access it, problem gone...   A lot of smart TV's aren't...

That means your path to Netflix sucks. Join an IX.

Wait, so just their IP is bad? Another IP is good?  Weird...

I have a couple customers who are testing poorly at fast.com, yet their
speeds are great on speedtest.net servers. Naturally they claim Netflix
constantly buffers and accuse me of throttling Netflix – we’re doing no
such thing. For giggles I kicked their SM for a moment and put their
pppoe account in a laptop at the NOC, set the throttle exorbitantly high
(100mbps) and let it rip. 2mbps to fast.com, 99mbps everywhere else.
Testing an adjacent IP in the same subnet will do 99mbps at both
fast.com and speedtest.net.

I would be on the phone with my upstream asking questions if other IPs
in the same subnet were experiencing the same results. This whole thing
feels like Netflix is targeting individual IPs with a throttle hammer.
Any ideas here?
