SM4 area very poor performance
 
Is anyone else here int he SM4 area havign bad performance this weekend?

I have a 50 Mb/s business connectiont hat has been all but unusable. Initially business faults suspected a duff Business Superhub and were going to send the on-call engineer to me yesterday evening.

This was after they tried to move me from one upstream to another, which didn't help.

I then got a call back to say that one of his colleages has seen very high network utilisation and this is almost certainly the problem.

This is todays Thinkbroadband graph:-

holy s.............. -uperhub

and I thought the business package got prioritised!

proves one thing though - VM are able to manually switch upstreams, just need to get a tech with half a brain. Is the business support team different to the normal one?

As far as I am aware there is no prioritisation of business traffic. The SLA is different (24 hours) and they offer static IP addresses and a different support team.

Yes he switched me to a different upstream while I was on the phone. The Superhub didn't change the 'channel' associated with the upstream, but the upstream power level did change.

The business support team is different - all support is handled in the UK and often they will get you through to an engineer that will log in to the CMTS right there and then and check things out for you.

Usually performance is good - but something has happened recently that has totally killed it durign evenings & weekends. 100 Mb/s has just become available in my area so maybe the torrent addicts are at work.

buisiness tech support is compeltely serperate i thin they have acces to other tools or can do more than what tech support for residential usere can do, second lien can swithc upstream but they genreally dnt want to do it

Just the last of a number of very similar looking graphs this week.

maybe they are shoving everyone in an area onto one upstream to free the other upstream(s) for bonding?

i thought it was they just had to do a lien card change so yeah you might get switched but once the psyhcila card was changed ythey could mvoe oyu back ingition would know the answer to that one better wherever he is

Well another evening of unusable business service. Was getting around 0.5 Mb/s earlier, but no service at all right now.

Business faults tell me this is now with the edge network planning team and to call back tomorrow

Hhm we'll see!

That looks good Magic - hopefully it'll stay that way for you. Still dire here - though it's actually working so far this evening - getting around 4-6 Mb/s on the 50 Mb/s business service. Still with IP edge network planning I'm told.

Well Virgin Media Business still haven't addressed the issues in SM4:-

They tell me the 24 hour SLA for fix doesn't apply to this... hm selective SLA then!

not bad that thinkbroadband ping log service, from the way it starts to lag up from 4:30pm looks like overloaded part of the network your on in your area not just SM4 as that cover an wide area (does virgin have any type of QOS on the nodes so it drops speed instead of packets like BT do)

just upgraded to 100mb speeds and speeds are still flying.

Magic are you also in SM4? Maybe it's just the CMTS I am on.

Does anyone know - is a given CMTS tied to serving customers on a given group of cabinets? I guess congestion could be either on the 'cable' side of the CMTS or it's connection into the Virgin network could become congested.

What I was able to glean from the faults engineer that did the tests for me I am on CMTS nmal18-2-0 and on cable 8/0/0. Would this serve one optical node that would then feed a few cabinets in a small region? I was on Upstream 1 and was moved to upstream 2 as that was slightly less congested, though I believe it's downstream congestion I am suffering. When I can do a speed test I find at peak times I will get around 0.5 to say 4 Mb/s down but around 5.5 Mb/s up. Being on the business service for 50 Mb/s my upstream profile is set to 5.7 Mb/s.

After escalating to the CEO's office after a week of 'no ETA' I am now told that they have escalated this and planning will be complete tomorrow with an ETA to be implemented by Friday.
