[OOL] is punishing encrypted YouTube straems at prime time?

Over the last couple of weeks I noticed that while using YouTube in https mode it is virtually unwatchable at anything over 480p from ~8pm until ~11pm.
Videos download at very slow ~2.5mbit/sec.
If I switch back to regular http they download just fine.
As a test I measured how fast this video will download at 1080p https://www.youtube.com/watch?v=YIBx0PoSqSg directly connected and when connected to my work VPN which terminates in Manhattan.
The picture above speaks for itself. :(
Anybody else noticed this?

I have boost and for the most part I get what I pay for.

You Tube is useless as it currently is. Best I can hope for is 360p unless I want to revisit Real Player from 1999. My daughter is constantly complaining about buffering of her ipad -(she says youtube is broken!)

OOL app works perfectly, Netflix also.

Why would you even want to view in https mode? It's not like you're at a banking site and since it is a Google owned property, they know what you're watching and selling off the demographic data to the highest bidder anyway. You don't really need that extra overhead for YouTube.

It's irrelevant "why" I want https. It is my decision.
Obviously you don't understand all the implications of HTTPS so perhaps you shouldn't chime in.

While anything is possible, I think it is less likely that OOL is doing anything to the traffic and more likely that you are using different servers for the VPN and OOL connection. Encryption is very CPU intensive and if the youtube server that you use via OOL is at all busy the first thing that will suffer is encrypted video.

What were the Google CDN IPs you were actually receiving the streams from?

Google's CDN management for YT has sucked for a good 2 years now, and no, that has nothing to do with OOL, but everything to do with their ridiculous month-to-month growth.

Sure I do. You must be one paranoid dude if you're worried about traffic monitoring and payload injections on YouTube. I've been to Defcon 17 and 19 and heard my fair share of talks about that.

Youtube doesn't have multiple POPs in NYC. So what are the chances that 100% of the time my OOL requests get to overloaded servers and 100% of the time my VPN requests get to an available server? For multiple weeks in a row.
If Google enabled https by default on all of their services, they know how much computing capacity they would need and i'm sure they have plenty to spare.

Yet the logic that OOL is doing it for only SSL to youtube and only during prime time is even more extreme. All OOL cares about is bandwidth used. Encrypted youtube does not use a significant amount of additional bandwidth.

Or maybe their snooping devices can't keep up at peak time..They are fruitlessly trying to analyze/decrypt it and this is how fast they can go when overloaded.
Are you saying CV doesn't use these?

Yet, I'm asking if anybody else noticed this pattern...

If they are using deep packet inspection, and for arguments sake I certainly will assume they are using it.

1. They almost certainly would not be trying to decrypt packets since it would be a criminal offense.

2. If encrypted packets slowed the deep packet inspection, it would slow your VPN just as much as it would slow your SSL. connection since the real difference between the 2 is the port number. Which is simply a number in the packet.

3. Packet Analysis is CPU intensive for every packet, so if you start to see traffic of one type slowed you are likely to see all traffic slowed, also in packet analysis from something like YouTube you likely would only really get new info from the first packet of each video. Sending Videos from YouTube is not CPU intensive but encrypting Videos is CPU intensive. If the CPU becomes loaded it should not have much of an effect on other traffic, mainly it would effect encrypted traffic.

Again much more likely that the place where there is a real difference in load, ie Encrypting the packet, is the bottle neck.

Chances are Youtube is just choking on itself. I have problems loading HD videos non-encrypted and FORGET about using it on a mobile device, it's just an awful experience. Even the Tivo has issues with buffering HD videos.

Netflix has a server on Cablevisions network now for caching but even before they had that it was still much better than Youtube.

Youtube has issues they need to fix.

Google has two pops in my data center. One for Google and one for Youtube. We are in Manhattan. I hope that those two servers are not feeding all of NYC. So therefor I would assume Google has multiple POPs in NYC.

I don't think there's anything criminal about that. We are using THEIR network. For all we know, they have some nation security letter that gives them permission to do that.
So keep that +1 in your pants.

There is or has been threads about youtube issues in about all of the ISP forums here with the same issue over the past couple of years. It is nothing new unfortunately.

An encrypted data stream is a electronic communication not readily accessible to general public. The wiretapping law makes it illegal to attempt to decrypt it, without a warrant.

Yes, but unfortunately, national security letter can override that.

Yes there have been. Even I created such in the past »[OOL] OOL throttling streaming videos?
And every single time comes out a train of OOL-apologists that ignore presented facts.
However, right now do you see people from other ISP reporting that SSL'ed Youtube videos are slow? If it is Youtube's fault, people on other ISPs will see the same problems.

actually, i dont know how many users would even bother to watch you tube via https / ssl.

EDIT-- I actually didnt know Youtube defaulted to https: on its own.

have you eliminated any variables between your connnection and your workplace? does business class ool have qos over residential connections on the network? is your business network set up to use different dns servers than your home network? since youtube routes you via your dns location this could alter things completely.
