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

Yup exactly … unfortunately we only see about 1% traffic on IPv6 to Netflix but 
it’s growing and will grow significantly in the next year with last mile 
changes to happen yet ….

Just did a speed test too fast.com and got 86mbps.  What I thought was
odd is it ran over IPv6 according to torch in our Mikrotik.

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

[Chris Wright]

This is the thought process I am going through right now. I just have a hard 
time believing they’d do something so obviously shady.

To sum up my responses to the other replies…

Issue can’t be with customer equipment because I replicated the problem by 
kicking their session and putting their pppoe client in a tech laptop wired 
direct to a core router at the NOC.

Can’t be with DNS nor upstream path because I verified an adjacent IP under the 
same conditions as my test laptop works fine.

I’ll look into this further by torching the connection at my edge to see what 
shenanigans I can detect.

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

[Paul Stewart]

I’ve heard that too .. not a fan of dumb TV’s .. err I mean start TV’s… they 
ain’t so smart often …

I do see fast.com <http://fast.com/> typically a bit slower than speedtest.net 
<http://speedtest.net/> - this is fairly accurate finding in my opinion as both 
are served on-net in our case so takes the network itself out of equation ….

Just did a speedtest from home at got about 25Mb/s on fast.com 
<http://fast.com/> and got 32Mb/s on speedtest.net <http://speedtest.net/> for 
example

I saw the same issue the first few times I tested on fast.com.  I am
testing at 45Mbps there right now though.  The first time I tried it was
2Mbps on a 60Mbps connection.
