I'm expecting a token charge around £10 or so but how informative/presentable the actual data is let alone "usefull" remains to be seen….

I'll hopefully be able to update here in a few weeks after also checking on "legalities of disseminating any info derived from the source" but suspect it'll probably amount to a "damp squid"….

what did they used to look like?

can they fix mine now?

and the other brig16 connection a Thursday in May:

Lancing is over subscribed and I can confirm that Lanc6 is bogged down a treat. The sooner Virgin Media do something about this the better.

Seemingly the network team is set to resolve this on 14/11/2012. But all I ever see on the VM forums are dates getting pushed back multiple times. So I won't bank on any fix in BN15.

ok what specific work was done in brighton then, I want the same in my area :p

Although of course I am not hopeful because as I understand it somehow the people in brighton managed to make lots of noise about it, press involved etc. and even then it took VM a long time to fix it, so my guess is what happened in brighton is above the normal congestion relief policies.

When I try to compare my US congestion to others in my area, it does seem as if I am on the only one bad channel because even other ip's in my ip subnet have significantly less jitter. About 5-10% or so have the high jitter rest dont, and even my neighbour a few doors away doesnt. But VM are stubborn and refuse to move me to a diff US channel group even with my neighbour on it. Whenever they talk to me about utilisation levels (CEO office) they just compare my US to the other 2 US's on my port so dont use different areas and groups which have much lower utilisation as a comparison. So given the barriers I have come across within VM this does seem unusual practice in how brighton got fixed.

Other than the fact you appear to have the same numerical number of CMTS chassis as Brighton (17), I don't see any other obvious (technical) similarities between Brighton and Leicester?

Unless you specifically know that your City planning/street works/highways have comparable "works" notification process, your HFC topology,age and RF plant is identical, same CMTS/uBR models, linecard types, configuration and up/down stream channel/freq plans, same HPPN, user demographics, churn rate etc etc I confess that with my ever increasing senility I don't otherwise see how you can accurately compare them with any sort of objectivity?

Perhaps you'd be kind enough to elaborate in simple terms for this aging retired network engineer?

Seriously though, there will be far too many variables to reach any objective form of comparison. It's still very much a post code lottery and VM don't elaborate on any useful details!.

Just for the record it would be churlish and naive to deny that local media publicity doesn't have some degree of influence on VM local strategies, however there has over past years been several articles (typically bi-annual) in Brightons Argus/Leader publications. Albeit, merely as a local resident I don't see any evidence that this has increased any more over the last years than places like Bristol or Newcastle?
Ergo I don't think anything "special" has happened but merely as a end result of longterm capacity planning?
Just check this help site for past issues 2+ years ago wrt Brig15 and BN2 area issues.
Perhaps you have specific links/stats to qualify your inferences?.

It is also rather premature to conclude all "over utilisation" issues in Brighton are "fixed" as inferred by your comments. There is evidence that additional bonded downstream channels have been deployed on many nodes over the past several months and that upstream bonding has recently started to rollout over the last week or so. However there also remains other RF (including SNR/FEC) impairments that still remain in some areas along with the potential requirement for VM to still address static and dynamic load balancing to "fine tune" after this years major Cat C re-segmentations where necessary?

In that regard it's entirely possible that VM CEO office refuse to change your upstream for entirely practical reasons. You probably know more details at what stage Leic14 et al CMTS and associated nodes are at in terms of upgrades & Speed doubling but to deploy a specific config for your Hub/CM would no doubt require excluding you from current load balance group and configuring your account/line connection for a specific u/s channel (and assuming this set's a precedent for similar requests) will potentially cause a disproportionate maintenance/admin overhead, particularly when they also eventually start to rollout upstream bonding groups in your area!

I really don't want to devolve this into yet another "you prove it is" or "I prove it isn't" time wasting discussion as those arguments are "Waring" a little thin… if you get my drift?
Neither do I want to antagonise/inflame you considering the real issues you're still encountering but I think we all (myself included) underestimate the complexities involved - and I'm not defending VM's lack of foresight / investment by saying that either!

Looks like some work has been done down lancing at the exchange. I have been informed that load balance measures have been taken with cables and upstreams. The job ref is still open while information on performance is monitored. I rebooted my SH and was placed on channel 51. I have only ever seen 49 and 50.

I hope this helps.

On a side note. Is anyone experiencing issues with buffering on YouTube?? I have been finding it terrible for days now.

BN41 has been upgraded about 2 weeks ago to the higher speeds, my 20meg is now sitting around 57meg

was more of a tongue in cheek comment. The reality is I probably wont be on VM too much longer hopefully so isnt a huge issue, but it is notable that you did get some publicity even if it was local rag only and have a very long thread on VMs forums, and even with those 2 things it took a long time for this fix to come about. I very rarely if ever see a ubr port go from super congested to looking very good, so to me it looked unusual, maybe you see it more often I dont know.

Yes the upgrades on my port are not existing other than what may or may not be planned for new products, as far as the CEO office is concerned there is no utilisation issue, but what was interesting is their information never matched to what tech support told me on the VM forums. I have had VM tech support on the forums say over utilised fix at such and such date whilst at the same time CEO office saying, is core network problem no UBR upgrade planned. So there is some misinformation flying around as well.

mine got done last night 30meg to 60meg, at last!, only nearly 18 months wait, well feels like it since 1st announced that we was getting the free double speed upgrade

Have you checked the roll-out schedule recently? For mine back in St Helens it got pushed back from September to December, putting in my address says March 2013 now

An interim update -
B&H Highways rang me this morning to explore the scope of my information request wrt VM street works.

While still awaiting the actual detail(2-3 week delay) we now have the following stats on Streetworks notices issued by VM in B&H area:

Past 6months = 750 requests/notices
Currently Planned as of today = 27 reqs.

Bear in mind that VM are only required to submit notice where the works will affect highways surfaces/traffic flow, so for example it won't cover cable repulls/repairs using existing ducting.

B&H now also partake(and my source says have done for past 3+ months) in roadworks.org which gives current status of ongoing works which is worth subscribing to using it's alert service and is therefore in the "public domain". (Assuming anyone is remotely interested of course! )

What I found interesting is when I enquired as to "amount of notice required prior to commencement" then I got this information:

Works upto 3 days duration = min 3 days notice
4 days and more = 10days notice
Works requiring road closure = 3 months notice!

Here's one example from roadworks.org which shows 5 day period of work in Blatchington Rd BN3 Hove to repair (what I surmise to be) ducting blockage:


Whether any of this goes some way towards supporting/defending/explaining or conversely challenging the "perceived protracted delays" in VM's upgrade (Cat C majors works) of course is questionable as VM won't expand on their equipment upgrades,procurement lead times and other resource considerations anyway.
