Would be interesting to know how the CDN works, technically.

IE, if you request an uncached video, are you redirected to a CDN node that has it, or does your local CDN node retrieve it from somewhere?
And if the 2nd case, maybe the issue is an overloaded inter-CDN-node network?

This largely depends on the Service, Service Levels, Provider and Hosting Environment (Facilities). The CDN services breakdown:

- Web Application Acceleration
- Content Acceleration
- - Static
- - Dynamic
- Network Acceleration

The above is coupled to DNS, Load Balancing and Storage (appliance or application based)

You are always served to the closest physical node which depends on 1) Routing and Peering, 2) Internet Latencies 3) Node Capacity and Availability.

Note: There are CDNs hosted in third-party Facilities, these Facilities may implement their own rule sets (policy-based) under agreement, which may cause additional variables to 1) Routing and Peering, 2) Internet Latencies 3) Node Capacity and Availability. In my opinion degrading the expected service levels.

To answer your question, technically you will request the closest available cache. Pending on the agreement and/or node distribution and/or policies between parties, it can be cached locally (appliance or application based). Interesting topic when you want to discuss net neutrality.

I haven't watched 4k videos - was busy working on something when the lazy schmucks did the test in the office ...

But this is exactly the point and why we have an open ticket on your marker for performance. There are dozens of reasons why performance can be suboptimal for any given client and there is the standard ring of "best effort service" (which is applicable on all of the links ...). BUT best effort should mean that - making an effort to get the service top notch and identify what can be fixed and by whom. Unfortunately this often depends on getting an arduous troubleshooting process and engaging with various commercial partners - which introduces delays and gives us premature grey hairs. This is also why we are so grateful for our supportive and engaging customers and why we welcome extensive and exhaustive feedback - including when it is bad news.

Sure- I'm all for testing stuff, we can see what we can do. I'll help wherever I can. We can chat tonight on Live Chat ( after the kids have been tucked in off course ;-) )

Cheers !

Its a date

wait that doesn't sound right
 
Just adding my feedback RE Youtube. I haven't had any issues with Youtube for a few weeks now. Able to stream 720p/1080p quite happily. 10 meg line, 10 meg uncapped account, Cape Town.

Watching Twitch is still a pain, but it turns out that many people (including people overseas with much faster internet than us) have issues with Twitch buffering or only working at low resolution.

Gaming latencies are still a tiny bit unstable, but are definitely getting better. I was able to play League of Legends the other morning with almost steady 200 ping.

Part of the reason why Twitch poses a problem is because unlike Youtube there is really limited investment from the proprietors of Twitch and it took massive outcry before they expanded their capacity in Europe:
http://blog.twitch.tv/2013/12/new-video-system-update-after-one-week-in-service/

Google are ardent genuine (as opposed to opportunist) proponents of net neutrality and as a result have invested heavily in a CDN network - it is this investment that necessitates the ads on youtube (but unlike your trust TV broadcasts Google allows you to skip an ad a few seconds in ...) and so on.

But there will continue to be work done to constantly improve the performance on twitch and gaming in general as well as to expand the capacity to take on more gamers in the world - its a public service mission, people can't kill people when they are virtual killing people ... ;)

If this is the case then could you explain why for example I can stream HD on Hulu with AH but on CW it plays for 30 secs and buffers for 30secs.
Often it will even drop quality to the lowest setting for a while.
Most of the sites I use as an alternate means when Hulu has nothing to watch, just don't really work unfortunately, Youtube doesn't have everything either.

I have been very patient and have stuck with CW, I don't however see a change in my international speeds via the mentioned sites.
At what point can I expect this connection to be solid enough to be able to stream(even if you class it as illegal, I don't understand why the differentiation) via sites like Filenuke, putlocker, billionuploads, etc.

I understand these services are not under your control regarding their throughput but then explain how I can get smooth video playback via AH for eg?
And please don't give me the money vs uncapped vs what can be offered debate; I never put a financial cap on what I wanted from a service.
CW offered me a product labeled as internet the way it should be.
This is what I signed up for yet I don't see the results I was expecting.
I apologize if this comes across as negative or an unhappy post but it's not my intention.
I would merely like to express my thoughts on this situation.

I'm in the Eastern Cape on a 4Mb Line.

ok hulu..........that's a problems hulu hd recommends 3mb throughput for HD if you can't stream that there's a problem somewhere. dunno what the cause is(CW/line/device on your end) but somethings going on there.

"sites like Filenuke, putlocker, billionuploads, etc." because they don't use streaming protocol(rtsp://) they use http so if your having international download problems obviously you'll have problems with them as well :/

just because you use "watch online" doesn't mean it is actually a true stream...it just opens an mp4/avi/mkv etc with a java/flash/html5 player on the webpage.

Yeah, look, this does sound like all I do is watch the tube, ( which is partially true, as i learn a lot from tuts that I watch ) , but this is just and example of a service ( in this case streaming ) which is supposed to work like a charm, yet we see vastly different results on the same type of links, granted that the results will never be exactly the same, but if Paul can watch a 4K video without buffering on a 10Mb link - I would expect to be able to do the same, and I can't - which to me is like I'm not getting the full benefit of a 10Mb line, if that's what it is capable of...

no one can watch a real 4k video on a 10mb line without buffering......it's impossible...no matter what anyone says that **** must be terribly encoded(CRF 50 anyone) or upscaled.......4k has at least a bitrate of 15mb-25mb(read average which means even at 15mb sync you will buffer from time to time no matter how good the isp is)

So how is Online Gaming on CW? is local gaming fine or is that also having problems?

I need to get a new 4mb uncapped account next month and I am planning to get a CW account. Mostly for gaming and streaming.

It looks like there is some International issues on CW, but I would be able to live with that if Local gaming is playable, e.g. dota 2 and battlefield 3. I'm in Bellville and I currently getting 3.5 mbps on a 4mb line when everything is going well, and 2mb when I actually want to use the internet...

I have stated on numerous occasions that the same services run just fine on other accounts.
I'm not looking to get into a retracted debate with anyone regarding these services.
It is fully understood that services I mentioned are not streaming services and that they are dependent on international line quality.

But as stated before, the same services run without flaw on numerous other ISPs.

Can I ask that you guys stop treating so many of us as imbeciles?
I fully understand the nature of these services.

(seems i fail at reading that you already understand that you know you can't stream due to int problems with CW)

nah it's not that i think you are stupid i just wanted to explain to people who don't understand that come read this thread....i mean seriously this is a public forum.....definitely not PM



EDIT:take it back just loaded something on putlocker on 720p @4mb uncapped its bufferless.....(on CW)


so i take it then that Eastern cape must have gauteng's problem :/ (if you want to see whats going on might be helpful to install bitmeter 2 i find it amazing to see what the hell your connection is doing)

In Brackenfell; CS and DayZ: SA over the weekend and had low latency throughout (<60); intl (EU servers) was sub 500, however the SO shared the bandwidth so could've been less.
Take note that some people are experiencing issues with D3.
 
Concerning the Youtube discussion, if anyone experiences a video that buffers, post the link so we can all test it out and report back our findings (with location, account type and DNS settings specified).
 
Hey guys. Downloading in EL area ain't good. 200kb on a 10mb line. Anything up (or down)
 
Same video, 1080p
Durban
CW 4Mbps uncapped
ISP-assigned DNS

No buffering, fully loaded by 3/4 way through (though I hear the unmistakable sound of iTunes radio playing down the passage :D )
