100% Proof of throttling twitch iptv etc.

Here's the proof of throttling - Once I vpn out of the vodafone throttling wall twitch is working perfect at full video source.

It looks like throttling is around between 3.8 - 4 - once I hit up onto the vpn you will notice i'm up at around 10 and playback is perfect

There's too many other customers on here reporting the exact same issue for it to be a problem our side - I've tested multiple routers etc to rule that out - I created this new thread because now we can see it really is a vodafone problem.

 

this is my speed

Can you give an estimation when this will be changed back?

Proof of throttling. 1.30 am

 

Initial 80Mbps..  Then 13 Mbps :)))) from same server. Just different traffic

Note that tracert to www.netflix.com isn't very useful because the streaming video doesn't come from there.


Then please, tell me what URL I should be doing?

 

Fast.com is giving me an amazing speed of 5.1Mbps, better than a few days ago, 1.2Mbps, IT'S BEEN FIXED /s

5.1 Mbps on Fibre VDSL... Sounds "a lot"

 

Try type in Google "speed test". It will give you HTML5 test right in front of you from Google itself

yeah..


 

@RIPTwitch I'm not sure of the precise mechanism Netflix uses. It was pointed out in another post though that if you checkout out this link (Firefox parses the list nicely other browsers don't by default AFAICS). That will give you a list of URLs that www.fast.com uses but the actual hosts and URLs vary each time you load the page. One of the hosts is for Birmingham and is called ipv4-c005-bhx001-vodafoneuk-isp.1.oca.nflxvideo.net where the c005 bit can change to anything between c003 and c006.

Yes the 3 vodafone Netflix "local" server clusters appear to be Birmingham bhx, Manchester man and Bracknell bbs - located closer/within the ISP's network so there is more efficient routing and less loads on internet interlinks for Netflix traffic. (Other providers do the same).

The routes to these servers (and other services, some speedtest, some download site) seem to be part of the issue.

The idea of these CDN (content delivery network) servers is in fact the opposite!

I just did reverse IP lookup of the Birmingham address (supplier by stevex)

 

https://www.ip-tracker.org/locator/ip-lookup.php?ip=Ipv4-c171-mia003-ix.1.oca.nflxvideo.net

 

Domain:IP Address:

Ipv4-c171-mia003-ix.1.oca.nflxvideo.net
198.38.125.200

 

 

I am at work so cannot try the trace route to the ip address via a vodafone connection. 

 

 

 

The test that convinced me something odd was going on (which can't be put down to just routing issues) was a set of tests using those URLs. Each one has a 25MB file behind it which can be used for speed testing.

My "full speed friend" and I did a crude test using Firefox and its speed indication when you download a file. For most of those URLs I was consistently getting well under 500KBps (that's bytes) while my friend was getting 1.5MBps or more. Using tracert we get identical results (apart from the initial gateway) to those hosts.

Stories on the forum indicate that people are getting speed issues despite using the same gateway as my friend: so it isn't just the case that there is a fast/slow gateway.

I had a couple of theories.

One was that tracert wasn't telling the whole story and some hidden part of the route did differ between my friend and I.

The other was that (intentionally or otherwise) some mechanism exists that tells something along the route to give me a slower transfer rate than my friend.

@stevex

 

I have run various download speed tests from the following website.

 

http://speedtest.tele2.net/

 

They offer small file sizes 100mb to 10gb both via http / ftp

 

I found in all cases (time of day didn't matter) the download speeds were mostly in kbps rather than mbps.

 

A 1gb test file was averaging 400-500kbps (which would have taken days to download)

 

These tests are all single file transfers which have been chronically slow not just from that website. I have tried Nvidia Adobe, Microsoft and AMD to name a few with exactly the same slow  single file transfer rate. The highest was Amd at 6mbps per sec.

 

I have run similar tests on my works BT connection and the single file downloads are at the expected speed of that connection speed.

 

I am currently paying vodafone for 900mbps service . :Hmm_Face:

 

@Shooto FYI on the 1GB file on that site I get speeds roughly 2Mbps my friend is around 6Mbps.
