Re: capacity issues - continued

I´ḿ on BT.....



Download speedachieved during the test was - 37.72 Mbps
 For your connection, the acceptable range of speedsis 27.08 Mbps-38.69 Mbps .
 Additional Information:
 IP Profile for your line is - 38.69 Mbps
Upload speed achieved during the test was - 5.34Mbps

Oops, not looking quite so hot. Is that with an HH5?

Re: capacity issues - continued

I'm sorry but why does everyone referr to the fateways as BNG or AG.... they should be referred to by their data centre location surely... so PCL = City Lifeline House PTW = Telehouse West PTN = Telehouse North
Each of these locations has BNG and AG names gateways....
SO:
PTN-BNG01 & PTN -AG01
PTW-BNG01 & PTN-AG01
PCL-BNG01 & PCL-AG07
Obviously there is a lot more gateways than just the ones I've listed above... and I'm not sure what the BNG or AG difference is though I assume its something to do with either gateway model or capacity...
So what BGN gateway was you on? PTN, PTW or PCL...
In my own experience recently, the worst issues have been on PTW-BNG01, however PCL-BNG01 shows a significant improvement though can have some speed variations throughout the day and PTN-BNG01 seems to be the most solid performer yet... but hard to get a place and then holding on to it is hard too...

Re: capacity issues - continued

The BNG gateways are newer models, and one or two (pcl-bng01 and pcl-bng02) are probably getting towards handling about 100,000 users each by now. The older AG gateways only handle about 23,000 users or fewer each.
You could also try and record the whole reverse DNS entry e.g. lo0.13.central13.ptn-bng01.plus.net, to try and determine if there's any difference in performance when on different central10, central11, central12, central13 parts, which might relate to the endpoint.

Re: capacity issues - continued

There's some very odd stuff happening here. Huge packet loss as soon as the storm started yesterday, which gradually faded away. And now today I have tried a test and speed is varying between 4 and 44Mb/s. Maybe water on the line? No crackling on the phone though.

Re: capacity issues - continued

Have you rebooted the modem after the storm.
It affected my modem router that badly that I needed to do a factory reset and reconfigure.

Re: capacity issues - continued

@Zad, the severe packet loss might not have been totally due to a Capacity issue, it could be the static causing electrical noise on your connection at the time. If it repeats itself when there is no storm, that's another matter and unfortunately at the time of posting it looks as though the BQM is starting to show that.
The TBB speedtest result is typical of some of the capacity issues being reported but as that isn't at a typical peak time, it's not certain. However, as the Formula 1 Grand Prix was being televised until just after then, it could be due to the volume of users streaming.
As ejs mentions it could be useful for users to post the whole entry eg. link-b-central10.pcl-ag06.plus.net or link3-central10.pcl-gw01.plus.net or link12-central10.pcl-gw02.plus.net.
The first part apparently represents a "virtual server" which may still have several end points connected. Whether those end points are always the same for a given connection I've yet to discover, but may well assist in discovering the part of the routing having an issue.
The easiest way to get the information is to either from a command prompt do a tracert ntp.plus.net - it will be the second line of the output, or the Gateway debug command in your browser should give the information near the end of the list. The last line will give your IP address if you are ping enabled so don't post that, just the previous line.
@bustermissy1961
As you know, you can often change routing and Gateway by gateway hopping (ie. log into the router, click "Disconnect" in the Internet interface to drop the PPP session, wait 30 seconds and then click "Connect"). There is currently no known way of users identifying problematic Gateway/End point combinations.
As an aside, as mentioned by npr, severe static can disrupt your router configuration which could result in bad performance (or none at all!) I have known cases where it's corrupted firmware that's then had to be reloaded as well.
So in summary, it could be useful for users to post not only their TBB graphs and/or BQMs but also the full ID of the Gateway they are connected to, as explained above.

Not sure what you mean, I was just pointing out that these speed issues seem to appear on BT as well.
If you look at my stats, you will see that G.INP is disabled at this point hence the lower speed!

As a more general question, apart from those that posted BQMs yesterday, apart from one other poster, I haven't seen any here in weeks. Is nothing showing up on the BQM?
I've been fine in all that time so no need to post. Should be fine now until October Smiley

Yours might be Andrue, so not expecting you to post, but unfortunately others clearly aren't so lucky.

That's because too often this thread is full dross and goading posts from one or two users so that others get fed up and just moan. We can at least try and get it back on track, and even without some sensible feedback from Plusnet we might narrow some things down to perhaps groups of end points even if we can't identify anything else.

Re: capacity issues - continued

I don't think there has been a single response from a member of Plusnet staff on this thread at all (and it was created in June). This should give you a clue as to what to expect...
