Can someone confirm Google Youtube streaming is under AIMS@raja chulan?

Google has their CDN within Malaysia. And it isn't located only in KL but other cities in Peninsular too like Penang and JB.

This is google peering data.
http://www.peeringdb.com/view.php?asn=15169

In Malaysia they uses AIMS to deliver local content.
I am wondering if this really the root cause of youtube slowdown.

Google peers directly with TM (you can do a traceroute), that link only states where in Malaysia Google peering point is located.

Well, TM and google do not have exactly a peering agreement, but more likely the latter has put a local CDN within the TM network.

So you are telling me that those other internet provider have peering policy with google thus they have no slowdown in youtube streaming?
While TM doesn't have one thus puting a local CDN and control all bandwidth of youtube streaming?

The CDN is put there by Google. Almost all other ISPs also do the same thing. If TM only peers with Google, TM will have to pay Google a lot of money because of unbalanced traffic direction.

So TM didn't pay to google?
Then how to explain slowdown in youtube? Is it the CDN peers by own TM?
Celcom Pay to google?

I don't think TM pays to Google, in fact I suspect is was the other way around.
The CDN servers are owned by Google. It works the way Netflix OpenConnect servers does. No peering, only CDN.

Then how come the youtube speed so slow.
It's clearly shown that the streaming had been throttled to 40-50kb/s.
The speed become normal at 1 am to 11 am
Google did that? Or TM?

Highly likely the problem lies with the CDN servers itself. Therefore Google problem.

Google limit speed? First time hearing it

I don;t think Google do it with purpose though. It is common knowledge their kul* CDN has capacity problems.

My youtube speeds are fine:

If you access YouTube via IPv6, the speed seems to be OK. It is the IPv4 YouTube that has problems, where people has to refresh the Youtube page just to get good speed.

Tried with IPv4 with similar results:

Doesn't tm traffic go to Google over myix peering?

Try this link:
http://youtu.be/L5eAWXiI4jA

This is my max speed download via Youtube app

Bandwidth isn't infinite.

Two minutes into the video and still at max transfer (I'm on 5Mbps Unifi) with IPv4:

BTW, what CDN are you reported in.

http://redirector.c.youtube.com/report_mapping

Like mine:219.92.x.x tm-pen1

Any other TM user and streamyx user which would like to test the video download speed?

Video less than 10mins seems to work fine. (Load at full speed) 450kb/s
But not video over 10 mins which is 40kb/s

110.159.163.227 => tm-kul10 (110.159.160.0/21)

Can you try download this video with any internet downloader?
And report back the speed.
You may need to modify the name of it. Because it will show [videoplayback] rather than <title>.mp4

Confirmed it is CDN problem.

Tested with the Kyoukai no Kanata video at http://youtu.be/L5eAWXiI4jA

tm-kul10



tm-pen2



The tm-pen2 sure has problems. So now kul* CDN is good while pen* one has problems.

How do you switch CDN?

Turn off IPv6 for youtube.com domain, then do 'recycle your IP address ---> check redirector.c.youtube.com/report_mapping' until you get the CDN you want. IPv6 users will always get kul* CDN servers.

Refreshed. Still getting lousy result.
BTW, Are you streamyx user or unifi user?
Try this and see: http://redirector.googlevideo.com/videopla...8790E12&key=lh1


Looks like UNIFI users aren't affected by this problem

Just do a simple router reboot or wan refresh.

I use Streamyx 4MB. That video of yours doesn't work here.

This is youtube now

Edit1:
But this speed is still not stable.
Tried download several times.
And few times is 40kb/s.
and All 114p video seems to cap at 40kb/s




And this
With that direct link...

Just go here and download simply a video.
Since this one uses google server.
Working hard to traceroute the video. But no luck.

If you use Firefox + Greasemonkey + Download YouTube Videos as MP4 script, it is easy to do traceroute from the server where you download the video file.

Sometimes, its very hard to understand network.
Now i am connected to tm-pen1 and tm-pen2
And I have full download speed. 450kb/s to 300kb/s
Just now download with CDN tm-jhb and tm-kul also no full speed. 40-50kb/s only.
Continuing to investigate this matter.

I am pernently on tm-pen2 for peering no mather how many time I reflesh

Peering might changes on refresh for certain user IMHO

I always got full speed BTW.

Unifi?

Streamyx 8mbit

Just got a reply from TM email saying 8mbps is not supported in my area.

My ADSL stat:

Seems can support, but nope.
Anyway to force them to upgrade to 8mbps?

Your ADSL stat is even better than mine.

My SNR around 2X
Attenuation lower than 10 for both

They replied that need in range with 1.5km with the DSLAM.
Anyway, I just saw a DSLAM within 100m and they say cannot support.
Can force the Tm technician come and install 8mbps or not?

I suggest you go to request at nearest TM Point after your SPM

LOL. Nearest TM point is about 35km from my place.

I got this results



How do I get the hostname for kul06s04?

This post has been edited by paultantk: Oct 28 2013, 04:38 PM

Thats a rare IP you got there. Anyway, are you on unifi?

btw this is result, 118.100.xx.xxx => tm-kul7 (118.100.0.0/18)

so what's good and bad about this? Thanks again.

Sometimes it can be good, other times bad. If you get low download speed from YouTube, look up what CDN you are using then recycle your PPPoE until you got a different one, then test the speed again.

This topic has been split from the IPv6 topic as it is off-topic.

Try YouTube streaming. See got any lag.
Try downloading the video if possible, since this give accurate reading of an video.

Alternatively, you can try download the video from this website with download accelerators or managers.
Then,report back the speed here.
(40-50kb/s = not normal, bad IP)
(Maximum speed of your internet= normal, Good IP)

Link: http://kissanime.com/

It uses google streaming server. (I don't know how they do it, but i am sure it is hosted via google server)

Good Job admin!

maxis business fiber

Thats why you got the not TM youtube CDN

at home on unifi i get this



i thought every ISP used the youtube servers on myix, didn't know tm had its own

I SP can decide and manage their peering to Youtube
https://peering.google.com/about/faq.html

Here's how people got it fixed, they blocked the CDN and YouTube player will use other CDN.
I don't know what is our CDN IP, figure it out yourself.

Thanks a bunch

i noticed that disabling DASH on youtube does fix the buffering/streaming issues..at least for my case.

tho you've to use 3rd party plugin, here
- https://github.com/YePpHa/YouTubeCenter/wiki#download

Haven't tried. But now I am under good Google CDN. I don't want to refresh my WAN IP again.
I will try when my WAN iP is refreshed.

Now back to square one again.
WAN IP refreshed.
The problem still exist on any CDN. Tm-pen1 pen2 kul10 . All speed is throttled.

To those whom are having this problem, not sure exactly what is the cause but disabling DASH as stated by GameSky seems to have a positive outcome

DASH = Dynamic Streaming Over HTTP.
It's supposed to give u just enough data flow to avoid any buffering.
Only just enough not to buffer, and also to save server or route bandwidth.

But it appears this feature doesnt operate as it should, causing the stream to be slow, and in the end buffers. If i not mistaken this feature is devoloped by Adobe and it's partners.

I'm using chrome and there's a way to turn it off.
https://chrome.google.com/webstore/detail/y...niapiiifn?hl=en
Use this plugin, open up Extensions page, enter the settings page of Youtube Options.
Under Playback section, there is an option to disable DASH.

Do note that this software is a customization software, it will center your youtube video and make the page as minimal as possible. You can turn it off. You can also set many settings such as hardware acceleration, force HTML5, set it to load HD or any quality of your choice, force HTTPS etc...

Also, do note that if youtube changes their site code and settings, it may break certain functions of youtube when you use this plugin. A simple turning off from the Extensions page will do. Have been using this for nearly a year, the developer is responsible n quick, the fixes usually come within a day or 2.

As for the problem from my experience, it is due to DASH not behaving as it should. Turning it off solved the problem without the need to refresh the page. Not sure if TM's setting causing DASH to fail or DASH causing TM to fail....

Woah that plugin works flawlessly, having slow youtube this few days even on tunneling, disabled dash, everything works nicely now.

Not sure whether is DASH fault.
Direct download video from google with download manager.
200mb max speed 40kb/s. (complete downloading need 1 and a half hour)
only from 1 a.m to 11a.m, Speed directly jump to 450kb/s. (which take 8-9 minutes to finish downloading)
I noticed this long enough since june 2013.

Complaint to TM. And they call back to me. Say want to come my house check copper wire. I say, its not my problem (my ADSL stats good), It's your TM fault. Other broadband provider (my preferred CELCOM) didn't suffer this kind of problem. They are like [tiada apa apa saja]. Obviously, they should forward this problem to the network manager, not those residential technician.

Later I will do a video comparision of the google CDN speed From 12.55am to 1.03 am

My first speed test video about TM throttle.

Hit them via Twitter at @TMConnects to get an answer , you'll be dealing with telekoms directly instead through their CS agents etc

If you guys have trouble with youtube streaming at 30KB/s cap before, i discovered click on address bar and hit enter to load the next page, the video will have a chance to switch to full speed when its being played. Not sure F5 refresh will work.

This is so far how i get around with those slow stream vids in the past month.

Great idea!

BTW, i am under good IP again. Hope that by complaining to the TMconnect twitter, the youtube cap speed will be abolished. It's not fair to cap people's youtube though who pay hell lot of $$ to the company..
