This is a bit strange !
Usually when I run a ping test using - http://www.pingtest.net/,  the program pings a load of servers and then proceeds to do a jitter test using the server with the lowest ping.
Normally the lowest pings (for me) come from one of about five sites in London - which seems logical because London is my nearest major gateway.  However tonight when I use this program, the pings returned in London (and presumably the rest of England) are so high, that I am getting lower pings from servers in different COUNTRIES !
The lowest ping I can get in London is 102ms, whereas Dublin is returning 59ms, and least jitter from Norway !



What the hell is going on ?  
If there is less latency from foreign servers, then is this bottleneck in Plusnet gateways or in the main BT trunks across England ?
:crazy:

Not for me connection is barely usable . And im connected to the gateway known as pcl-ag04.

[Kelly]

I'm really sorry about this guys.  I've got people trying to work out what's going on.  
Purleigh:  What gateway are you on?

[jamesanstee]

Im starting to lose faith in the We'll do you proud slogan as at the moment this issue does seem to have been ongoing for sometime.

[Anonymous]

I'm still on 'ptn-ag01'

[Kelly]

Purleigh: I've think I've figured out what's going on with your connection.  I didn't realise you were still 20CN.  I'll talk with Dave about it and try and sort tomorrow.    I suspect your problem is different to everyone else.

@Kelly:
Does it involve a free upgrade to "Max Premium" - to get the most from my 20CN line on a never to be upgraded 'Market 1' exchange ?.
PLEASE ?
PRETTY PLEASE !

[Kelly]

Sadly, I don't think that will help.  :-\
jamesanstee:  Sorry dude :(  I'm working on it though!

[Anonymous]

@Kelly:  Are there any other tests you want me to try tonight to test your theory ?

[Kelly]

I suspect it's fine now?  Yeah?

More problems with tvcatchup.com tonight.  Ping trace to tvcatchup is normal / my connection Speed tests are normal 4.7mbit / wireshark capture is normal all incoming packets tagged as 0x80.  Yet still buffering every 60-90 seconds on all channels, if it was just one channel then it could be a problem with that channel, but I tried all BBC/ITV and a few others with the same results, too many with the same fault says its not there.

Yes I have still have full speed, and pings have returned from >100ms, to about 40ms (rather than the 23ms I used to have) - which you said is due to interleaving having been applied to my connection.
Is my line stable enough to have interleaving switched off ? - my router shows maybe one or two CRC errors per day.
