Nottingham Core......crumbling?
 

People from my area seem to be lagging, lossing on games, variable pings. Anybody finding the same problems?

ps I've forgotten the switch for amount of pings ;o

Re: Nottingham Core......crumbling?
 

well my modem is crashing tooooooo often, but i have the 120 so phoning up for a tech to come out and he will i guess "sort out the power levels" till i crash it again and get the 250 modem <_<

Re: Nottingham Core......crumbling?
 

It's not just you. I'm in Loughborough and am having f***ing awful problems tonight. The Leicester side is exactly the same... I've already been onto CS about it. I can't browse very well, and gaming well just forget it, I can connect to a server for about 30secs before the high pings get me kicked off...

I've got an engineer coming on Thursday to hopefully replace this pain in the ass Terayon C/M. What's the betting that it doesn't clear the packet loss problem though...

Re: Nottingham Core......crumbling?
 

Yeah the constant packet loss problem seems to be across the board, I know people with a 250, 120 and surfboard 4100 and all have pl.

So people may be able to get good speeds even with the pl, can browse unnoticeably, but thats just the constant pushing of bandwidth along, not the rapid reliable response games require :/

Maybe somebody around ntl is aware but are simply not bothered. Look at the Amsterdam issue, I can't remember the last time nl servers gave me 0 pl, which they always used to, its shows as 15-25 on cs all the time.

Comparable traces now -

Re: Nottingham Core......crumbling?
 

Your original traces seemed to suggest a problem between hops 3 & 4 rather than the core (which I believe would be your link into Nottingham).

Re: Nottingham Core......crumbling?
 

Actually I'd say his original traces suggest more local problems to uBR:

2 33 ms 89 ms 32 ms 10.153.175.254
2 21 ms 39 ms 79 ms 10.153.175.254
2 22 ms 36 ms 72 ms 10.153.175.254
2 41 ms * 27 ms 10.153.175.254
2 16 ms 41 ms 66 ms 10.153.175.254
2 76 ms 74 ms 111 ms 10.153.175.254

All over the place.

In the wee hours the issue disappears:

2 8 ms 7 ms 11 ms 10.153.175.254
2 8 ms 7 ms 9 ms 10.153.175.254
2 7 ms 11 ms 8 ms 10.153.175.254
2 19 ms 7 ms 8 ms 10.153.175.254

Note that with those traces even though the transport and core routers, cam and core, still ping higher intermittently this is expected behaviour from a router running BGP and it doesn't affect the ping times to the end destination.

As far as this fault goes I'd either say there were capacity issues there, either it's a temporary loss of capacity or your upstream / downstream are busy. I'd guess upstream looking at the packet loss, etc.

Re: Nottingham Core......crumbling?
 

I gave up with everything last night. I couldn't work at all :mad:
I lost count the amount of times that my modem lost connection. I think that there must have been major problems last night that they didn't want to admit. I phoned CS and they said that all was OK, no problems in my area... Yeah right!!!
Only good thing about it was that I've managed to get an engineer to come out Thurs to replace my modem...;)

Re: Nottingham Core......crumbling?
 

I am surprised noone has picked up on 195.66.224.220

Although you the first person who can compete against me for been on a crappy ubr, the 195.66.224.220 router is defenitly the main problem concerning the packet loss.

Tracing route to 213.251.146.93 over a maximum of 30 hops

1 13 ms 40 ms 11 ms UBR [10.8.143.254]
2 23 ms 119 ms 36 ms leic-t2cam1-a-ge914.inet.ntl.com [82.3.35.149]
3 36 ms 7 ms 9 ms leic-t2core-a-ge-220-0.inet.ntl.com [82.3.33.10
4 30 ms 13 ms 50 ms lee-bb-a-so-220-0.inet.ntl.com [62.253.188.110]
5 12 ms 24 ms 11 ms nth-bb-b-so-000-0.inet.ntl.com [62.253.185.101]
6 15 ms 12 ms 22 ms nth-bb-a-ae0-0.inet.ntl.com [62.253.185.117]
7 16 ms 40 ms 18 ms gfd-bb-b-so-400-0.inet.ntl.com [62.253.185.98]
8 21 ms 19 ms 18 ms redb-ic-1-as0-0.inet.ntl.com [213.105.174.138]

no packet loss up to this point just fluctuations

9 121 ms 128 ms * sw1.tc.lon [195.66.224.220]
10 123 ms 124 ms 123 ms rdb-1-m1.routers.ovh.net [213.251.130.14]
11 124 ms 105 ms 104 ms 213.251.146.93

hop 9 onwards consistent 100+ ms and some packet loss.

Re: Nottingham Core......crumbling?
 

Looks to me like that router just doesn't respond to ping requests when it's busy. The times beyond it seem ok.

Re: Nottingham Core......crumbling?
 

nah they not ok if you see further up the thread the normal latency for the last hop is 30ms so the 100ms jump carried through.
