COVID-19 vs. our Networks

Fri Mar 20 15:00:15 UTC 2020

Because they're trying to be a responsible Internet citizen instead of just telling everyone else to bugger off. 

Perhaps if more entities tried to be responsible instead of entitled, the Internet wouldn't be as bad as it is?

It is something that matters, because it has the potential to set a dangerous precedent. 

If you say "$Service should reduce their bit rates because this is an emergency!" , I guarantee that exact same argument will be made well after this crisis has passed with a different definition of "emergency", and adding on "well it's an emergency to me!". 

Some of the pipes Netflix goes through is also used by other services that aren't as adaptable. 

And how is that Netflix's responsibility? They have already taken action to ramp down bitrates when they detect congestion. Why should other applications be able to say piss off, I don't want to? Didn't we just have a 10 year net neutrality argument that we're not supposed to want to treat the bits differently?

It's one of those most important things that matters. 

The end user likely won't notice the difference between 4k and 720p. They also aren't likely to notice the transition from one to the other. 

The person on the VPN, VoIP call, video conference, video game, etc. will very much notice the congested link, even if it's only a few seconds. 

Yes, Netflix video is very efficient, if not the most efficient. They're also one of if not the largest slingers of bits on the Internet. Small changes in usage of such a huge player totally eclipse most other usages on the Internet.

Netflix recommends 25 megs for Ultra HD, while only 5 megs for HD. That's a 5x difference in something people likely won't notice and would make a big difference on the additional VPN, VoIP, video conferencing, etc.

Yes, but does that matter? If there's extra capacity on the link, Netflix runs at full rate. If there is not extra capacity Netflix rates down to prevent congestion. While streaming video (including Netflix) uses a lot of bandwidth, I don't see Netflix causing congestion. It gets a bad wrap, and I think that's unfair because Netflix is actually really efficient and really conscientious compared to others.

Across several eyeball networks I'm not seeing any noticeable increase 
in peak (95%) demand between now and January. Since Netflix 
automatically scales down data rates in the event of congestion, the 
only thing I foresee forcing Netflix to reduce data rates [ahead of any 
congestion] would accomplish is causing excess link capacity to go 
unused (wasted). This sounds like a policy decision made without a 
technical argument... e.g. not a data driven decision, but a decision 
made out of fear or panic.
