You can go here to have a look at how NZ fairs:
https://www.google.com/get/videoqualityreport/#

 

From this article:
http://www.gizmodo.com.au/2014/07/youtube-is-naming-and-shaming-australian-isps-for-poor-speeds/

>>
Netflix has spent the last few months shaming slow ISPs for their terrible service and speeds, and now Google is out to do the same, expanding its ISP HD streaming report to Australia. The results aren’t pretty.

 

Google is now measuring ISPs based on their ability to stream HD content to customers from its content delivery networks (CDNs).

 

Australian ISPs have been under the Google microscope of late, and the results are unsurprising: unless you have the NBN, your YouTube experience probably sucks.

 

Here’s how Google measures ISPs:

 

 

A typical YouTube video playback consists of a YouTube client (player) fetching video bytes in a streaming fashion from a YouTube server (CDN), in one or more requests (e.g. HTTP GET). The first step in determining ISP ratings is to measure the sustained speed at which these video bytes are transferred from server to the client. To measure the achieved application level throughput (goodput), the following are recorded for each request:

1) Request Identity: The originating request’s timestamp, access network (e.g. network block, autonomous system number of ISP) and the coarse geographical location (e.g. country, metro), derived from client attributes such as IP address, User Agent, etc. Note that the IP to location translation done by our automated systems may return a location that is incorrect for some users.
2) Response Size: The number of application bytes (including application headers but excluding any kernel level overhead) transferred by the server to the client, in response to the request.
3) Response Time: The time taken to service the request by server, including network transmission time (all bytes acknowledged by the receiver).

Based on these measurements, the goodput for a given request ‘R’ is computed using the formula below. Each measured request is considered a goodput sample.

 

 

From there, Google and YouTube assign each ISP a rating. To achieve a certified HD rating as an ISP, your results need to indicate that 90 per cent of connections made are able to sustain a HD (720p and above) stream.

 

Only four stand-out performers earned themselves gold stars from Google and YouTube: one is Telstra Cable Broadband; another two are NBN providers (SkyMesh and Activ8Me), and the fourth is Service Elements, a wholesale network provider.

 

One of the poorest performers on average is Dodo, ranking low on HD streams around the nation.

 

Check out your ISP results here, and compare the ones that maintain good connections to see if you should switch. [YouTube]

with caches and such for google,youtube all over the place should be no reason for poor streaming quality,experience... alot of the problems would come down to the last mile connection- people in areas with conklins etc....

Interesting:


Please Google explain this, How the ALL MIGHTY Vodafone doesnt get HD cert... Look at that 4K, No buffering, 38Mb/s streaming rate. (stable)


Did take note to the fact they include Telecom BUBA, All those people that complain about how they ant watch videos on BUBA. Well here is solid proof they can:

If I was an isp I would kick people off that complained about speed and had no filter etc to get the rating up.

Or put them in an ip pool identified as something else.

Posting from a HD Certified Snap Connection :D

But really, interesting to see. Essentially anyone who has a youtube cache and a network that doesn't suck, and ticks whatever other boxes Google wants is going to be able to stream HD.

That has to be a bit of a jack up just to get ISP's to put google caches in their networks.

Like Tim has pointed out above... Vodafone's "quality" graph is very very similar to Snap's and yet they are only SD verified?!

useful for the USA, where last mile is pretty good (since it's mostly cable), but where ISPs are known to throttle 'over the top' video services like Netflix and youtube to protect their own Pay TV businesses.

Not so useful for NZ, where ISPs don't have pay Tv businesses to protect (except VF) and where the length of your copper line is by far the biggest determinant of your ability to stream video, so ISPs with a higher proportion of rural and ADSl customers  (Telecom BUBA) will look 'worse' than ISPs who focus on urban areas and sell more VDSL and UFB  (Snap, Orcon, Slingshot, VF) even if the performance on an 'apples with apples' comparison is identical.

Using imgur is easier than the upload thing on this site.

How is it easier? Just because you can upload a huge desktop screenshot? You can do the same here on Geekzone too:



Does it help?

No. What helps is to CROP the image:



People can just do one second more work and make things better for everyone else. If the images on other hosting sites were cropped I wouldn't have a problem with them.

I think until Google sticks their own servers in New Zealand then it's moot.

Google has servers in New Zealand - most large ISPs have Google servers. The problem is that Google doesn't "put servers in New Zealand". ISPs have to give Google the colocation and the bandwidth. Google put a box there and use the traffic for free - including for other services not only YouTube.

That's how they got so large footprint.

the caches don't really stop google sourcing some of their content from distant locations via australia.   i think it's better than it was now, but it used to be that some stuff came from the netherlands when i was exploring poor youtube performance in the past.   and often it was lower def rare videos that were more likely to give issues.

These stats do not discriminate wifi. Ie all smartphone and tablet use on YouTube is included, and with old wifi standards still used on lots of home connections this is more of a comparison of modems than connection speed
