Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I have a SH2, so it shouldn't have been that. I'll check my uptime later to make 100% sure though. I don't think it was a reboot as I get the usual ~300 Post RS errors on each channel when my SH resets and there was 0 present.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I don't see any spike on your graph, but assuming you mean what I think you mean, such events can be relatively normal network glitches that happen once in a while that may or may not be anything to do with your line.

Well, I've given the Forum Team a nudge as to what should be done!

If you search in this forum on the keywords CRAWLEY and RAMPING, you'll see a huge thread on the subject, led by THENRY. It's that wretched SH1 that's the cause of this particular problem.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Much appreciated!

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

so looks like a typical high utilisation graph to me, usual over subscription issues is my guess.

Shame as I had the impression from what I read on tbb, VM were getting rid of these issues of under investment.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Should add, high local utilisation. It most certainly isn't congestion affecting the "whole network", unless VM meant the "whole local network"...

Localised congestion is usually one of the slowest types to get fixed unfortunately.

Congestion affecting the "whole network" tends to be fixed very quickly, particularly given it affects high-paying businesses and has a habit of hitting the news.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

yes I meant node/local congestion.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I'm in an area that apparently (according to VM CS) has very high congestion and is touted for an upgrade in September.

I can't shake the feeling something else is at play however as the packet loss is monumental as you can see.

I'm in the Nuneaton, Warks area but others as far away as Nottingham have reported this and been given the same reference number:

it does my nut it that after all this time and documented evidence that shub1 is pants in so many ways that they still have it on the network. Surely they must be more trouble than they are worth.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Not really. They aren't going to recall the CPE en masse. They'll just do what they have been and change them as they go wrong and customers complain. Cheaper and less work.

They are pants though.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Yup, exactly. They're only "more trouble" when they're costing Virgin money. Most of the people still using the Shub probably don't realise how crap it is.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I see BT Wholesale felt left out of the congestion issues. Having allowed one of their core POPs, Manchester Dial House, to congest a couple of months back and fixed it they seem to have allowed another couple to have done so.

Each of the two new ones account for ~5% each of the user base using that BT Wholesale product. In the case of Plusnet that's about 90,000 customers affected all in.

This ignoring their more localised issues with capacity out of exchanges.

Looks like there's something afoot in Bristol, I've been told there's an imminent fix due for long-standing utilisation problems, and for the last 3 nights my TBB graph for BS37 and another I run for a friend in BS14 have the same spike around 11pm...

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Unsure what exactly has caused it but it looks like one of VM's connections to LINX is running over capacity.

Traffic has been rebalanced between the links, see if this improves things more tonight :)

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Have they not upgraded to 100Gb yet?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Depends if you include the 100Gb UPC / Liberty Global have.

Virgin / ntl have a long history of carrying considerably less LINX capacity than their peers, preferring to peer in more locations and have more entry and exit points on their network.

Many haven't upgraded to 100Gb to be fair. There are only about 25 100GbE ports lit on LINX. Akamai alone have 6 of them, Apple have 2, Facebook have 2, Microsoft 2.

ISP-wise BT have 2, Sky have 3, TalkTalk have none: they use 32 x 10Gb.

VM use 23 x 10Gb on the London LANs. Their network pushes >4Tb/s at peak so they must have a ton of other public exchanges, private peering and transit taking the strain.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Well that depends if they're using it to carry VM broadband traffic :p:

That's true, but VM also have several times higher average speeds than Sky and BT, and BT for that matter have had 100Gb LINX ports since at least 2011. EE also have two. Basically everyone bigger than VM has multiple, despite VM having higher average usage per customer.

Unfortunately I see that as part of the problem, as it's much quicker to add public peering capacity than new private peerings when dealing with unexpected traffic increases.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

It is but then causes issues as far as how you actually get all that traffic robustly and resiliently to that public peering point.

Comcast, etc, run the same model for pretty good reasons. VM could ram all 4Tb/s through London but not a good idea. It may be quicker but it's unwise, far better to try and get traffic off your network as soon as is feasible.

It's a different equation for Sky as the heritage of their network is the old Easynet network and a massively fibre dense ring in London and for xDSL ISPs as they can centralise IP traffic and use BT Wholesale as a transport network but for networks like Virgin's where customer traffic is clear IP very close to the customer makes sense to have a bunch of exit points.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Could one of you who's more clued up about this than me tell me if this is good or bad?

https://www.cableforum.co.uk/images/local/2015/06/8.png

Been running the monitor for a few days now on our connection and it generally seems to follow a similar pattern to the above in the previous days as well. This is from the SH2ac directly at the moment, not in modem mode. Whether that's what's causing the issue and a better router would fix it I'm not sure.

I would have thought the latency spikes would be when the connection is getting used, but they seem to be fairly regularly spaced, even through the very early morning when the only devices connected to the router are phones/tablets in standby.

I haven't noticed any connection drops or slowness and generally I'm happy with the connection so far, but that graph does seem to have more regular latency spikes than some that have been posted here.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

http://www.thinkbroadband.com/ping/s...07-06-2015.png

The above is a SH2 in router mode.

The below is a SH2ac in modem mode on the same VM segment.

https://www.cableforum.co.uk/images/...2016/02/30.png

So there is a defo difference in BQM behaviour as between router and modem mode but not to the extent of the spikes shown in the dead of night on your circuit.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Some routers are a little more 'casual' about responding to pings on the WAN than others :)

EDIT: What are the first 3 octets of the IP addresses each of those have?

Mind tracerouting from both to 80.249.99.164 please?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

80.0.88 SH2
82.22.154 SH2ac

Won't be able to do the traceroute till tomorrow (Saturday) as at the seaside right now.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

BTW, Igni - they are always like that and during the bulge episode the two circuits behaved differently i.e. one had the bulge the other didn't,

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Different subnets, different routing. Basic networking 101.

Your traffic is taking completely different paths so the difference in the BQM graph and bumpiness has virtually nothing to do with your equipment.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I knew all that Qasi.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

And yet your posts state the exact opposite.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

They state nothing of the sort. You tell me where?

I was answering PJLFC as to the BQM difference in modem mode vs router mode.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

You post two graphs and say there is deffo a difference in router vs. modem mode. Then you say you know the difference is nothing to do with router vs. modem mode.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I said nothing of the sort. Read what PSLFC asked in his immediately previous post.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Yes.

Your SH 2 AC is, on the return path, going via the Extreme LINX LAN, your SH 2 vanilla is using transit for return path.

Both are using transit outbound.

This was, however, different previously.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

can you ping the superhub AC on modem mode? how did you do that Seph?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

You mean with the Thinkbroadband BQM? You just register on their site and follow the instructions for setting it up.

It's not the modem that is pinged but the router behind it. It gets tricky if your PC is directly connected to the modem. Or rather to say I haven't tried it.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Ermm, you mentioned no previous post and quoted no previous post. And you said exactly this sort:

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Are you blind? My post immediately followed the post I was answering. I was addressing this observation in relation to the BQM by that poster:

"This is from the SH2ac directly at the moment, not in modem mode. Whether that's what's causing the issue and a better router would fix it I'm not sure".

If you can't accept that then your motives are questionable.
