When trying to stream 4oD it seems to be so intermittent, one night it works, one it doesn't.
I am sick of hearing from Karoo that "there was no specific problem that evening" and "we are carrying out work to improve broadband speeds".
When I signed up to Mid 2 I was ensured this problem would go away, no shaping. Yet, it doesn't.
On Sunday, out of interest, I set up an SSH tunnel through a VPS in London.
Without, the stream was so choppy, every 2 or 3 seconds on adverts, 8 or 9 on content. Through the SSH tunnel, no buffering at all.
When I do a traceroute from my PC, without a tunnel, to the VPS and to 4oD, both go through a router 134.222.146.54, 4oD is then 2 hops ahead, VPS 4 hops ahead. So both are taking a similar route. Both the VPS and my PC are being served by the same "Akamai" server.
I'm trying to come up with a reason why one is faster than the other, other than deliberate shaping by Karoo?

Hi,
There is definately packet shaping going on
If i stream via port 1935 I get average 600kbs
Via port 80 1.2mbs
If I do multi thread I can achieve 6mbs total, so each thread is thottled
All I know from extensive talks with there techies, is that there isnt enough bandwidth to go around now, with more people using video sites and down streaming for 1hr+ at a time (films and progs)
My connection has been capped at 2mb even though I sync at 12mbs on both lines
Not very happy either
Keith

Lets face it we have all been conned .
We opted to upgrade to a package to stop this and lo and be hold it is no different,
I am on pro 1 that also is a bag of sh*t I can stream live streams but only out of peak times in peak its buffer buffer stop start. and not just youtube but many sources of streams .
It is purely down to the amount of bandwidth that is fed to us which is obviously not enough

It's funny, Karoo Helpdesk always make you feel like you're the only one "no issues". I wonder how many 100s of people they tell there are no issues at a time  |

Yep they're shaping per thread. it's the same with youtube and other high bandwidth content providers. the only one that seems to not be affected as much is the BBC. I have to wonder if that has do with the fact that the BBC did threaten to expose and shame any ISP that shaped their service. |

Even iPlayer tonight is not perfect.
iPlayer traffic does leave the KC network, it's no shorter a route than 4oD.
It goes through that same router: 134.222.146.54

That router is in Amsterdam... That would explain the reason Speedtests are so fast from there and confirm my suspicions on a few other things.

Its a fast network
ldn-s2-rou-1041.UK.eurorings.net to karoo 32ms
alot of server are being hosted in amsterdam due to the connections to uk, and far cheaper transits

They could have a transparent proxy in place caching content and it wouldn't show up on a traceroute. |

Although a Dutch provider, KPN, that router appears to be in Telecity or Telehouse, London. Even iPlayer tonight is not perfect.
