Virgin Cable Gone Bad


[link to this post]
 
I have been using 120Mbps Virgin Cable Broadband near Portsmouth, UK for over a year now and been able to download files and updates from most servers at around 11 MB/sec, untill about 5 weeks ago.

Then suddenly over night, virtually all downloads & update speeds have drasticlly reduced to around 450 KB/sec when the download starts and within less than a minute has reduced to around 50KB/sec and then slows further stile to less than 56k modem speeds, sometimes in a few seconds, and more often than not stops halfway through, 0KB/sec. Even worse still some websites are unreachable. Just one of many for example http://www.freeview.co.uk/ . They eventually time out and I just get a blank page.

Also streaming video from youtube starts on default 480 resolution then sometimes drops to lower resolutions and buffers and stops. Audio from BBC iPlayer radio buffers constantly then stops.
iTunes updates start slow and stop before finishing, so unable to update. Mobile apps are the same so unable to update over wi-fi, only on 3G.

This all happens on all my devices while connected through Virgin cable, over ethernet cable with 1Gbps to superhub 2 connections with windows 7 x2 PC's ( with or without anti-virus installed) and 2x PC's with 1Gbps ethernet connections with Ubuntu Linux installed. Also happens iPhone & Android on 5GHz Wi-fi to Superhub2.

All devices work perfectly when connected to 3G internet, with faster download speeds, all downloads finish and all the websites I cannot get on virgin cable are availble over 3G mobile internet. Even on windows 7 PC's and Linux PC's when I conect to 3G internet via wi-fi to either of my phones using the built-in wireless hotspot feature. So I know all my devices are working correctly, and the only common failure is Virgin cable.

What is stranger still, is if I use OOKLA speednet's test, it says I have 128Mbps download speed (11Mbps upload)on all my ethernet connected devices and 80Mbps d/l (11mbps upload) on 5GHz wi-fi devices on virgin cable. But that is the only thing that does. It says 2.9Mbps TBBx1 & 23Mbps HTTPx6 on this sites test for example (11Mbps upload). All other speed tests i've tried say around 5Mbps download and 11Mbps upload.

Does anyone know why OOKLA's test is good and all other tests have half the download speed of the upload speed on all devices?

When the Virgin Media technician arrived and before I had a chance to say anything about my problems, the first thing he did was connected his mobile device over my 5GHz wi-fi and said "Theres is nothing wrong with it". And showed me his speed test result on OOKLA speedtest ( I thought it was bit strange that he would use that as his official test of my internet connection ).

When I demonstrated the actual problems, he blamed every single problem through the virgin cable connection as a problem with every site I was going to & that if his speedtest on OOKLA was good then theres nothing wrong.

When I demonstrated everything works fine over 3G internet including my 2 windows 7 PC's and 2 Linux PC's, he said "it's done differently on 3G" and his comparrison was "You will get some websites over 3G internet that you won't get on virgin cable internet. Just like you won't get Sky movies on freeview televison!" I was dumbfounded & almost speechless that he said that.

So after an argument that almost sounded like a Monty Python sketch from the point of view of anyone that might have been listening in, he fitted a brand new superhub 2, coax & splitter.

Guess what! It was still the same!

Any thoughts and ideas would be appreciated folks.

Thanks in advance.

Sounds like congestion and would guess that VM prioritise Ookla over their network.

Virgin Media is the biggest liars! They still using traffic management on download but will not telling you (their secret) to avoid ASA complaints even thought they say the traffic management is no longer on download. They still using it in secret.

Virgin Media appears to have certain peering links that are suffering congestion while others do not.

It has happened in the past and we have temporarily in the past forced traffic between Virgin Media and ourselves to go via other links to show this, and seeing what we do then we have no reason to suspect otherwise this time.

It is not just you, we have seen a downturn in Virgin Media cable speeds in the last few months.

Setting up a Broadband Quality Monitor from this site on your IP address is a good way to see if you are experiencing congestion. I can see from mine that the network gets busier between 4pm and 10pm as ping times are longer and this also coincides with a reduction in download speed from the nominal 100Mbit/s (also on Virgin). Upload, though slower at 6Mbit/s, seems to be less affected. That said, I have never seen the type of drastic reduction you are getting and the sudden onset is also surprising. The technician's comments are laughable but he may only be qualified to diagnose/setup your local connection and may be unaware of a fault or overload deeper in the network. I would try to escalate this fault again and also try the Virgin forums as has been suggested. Also Ookla speed test results seem to give similar results to thinkbroadband for me.

They still shape traffic on downloads and have not made any secret of that.

There is no traffic management on downloads.

Of course if you have proof, rather than libeling...

Those to statements are incompatible. If they are shaping traffic then that is management.
