Performance getting worse

[#1]

What are you doing to our faults checker
If you want to leave it where you are, I'll finish getting it raised.

[#2]

I had this - you need to say "The Broadband light is flashing, changing colour or it's off" otherwise it tells you your service is fine (despite highlighting the performance as an issue).

@jelv Can you open a fault ticket for us? We can see if there are any less congested VPs and try to get you moved to one.

If I'm having problems raising an appropriate fault what hope have most average users? I shouldn't have to lie as Andy has said.

[#5]

Right. There are 8 VPs I can see at your exchange from the report on the 4th Feb.
5 AMBER, 1 GREEN and 2 BLUE.
You're on the GREEN one, so in the date range used to compile the report there was no capacity issues.
I'm going to ask someone more faulty than me to have a look and see what they suggest.

In case anyone thinks I'm just complaining about poorer speed test results, it is affecting me.
I have Microsoft Lync up nearly all the time. During the day it's fine. Recently I've been finding that in the evening it frequently loses connection to the server.

[#7]

Which queue should Lync traffic be in (hint it can be used for making calls)?

[#8]

I'm sure I've seen someone else mentioning lync, and had supplied a wireshark capture for it. I believe we were adding a signature for it to the system in December, so it should be classified correctly, Any chance you can wireshark it and upload to a ticket? I'll ask the guys to take a look asap.

[#9]

Does classification apply correctly to IPv6? I've just been looking at a Wireshark and spotted that a lot (but not all) of the Lync traffic is IPv6.

[#10]

I'm not 100% sure, however we'd always suggest testing without any IPv6 tunnels etc just to be sure.

[#11]

check this thread as could be same issue.

Also Chris note please I posted an update.  The trigger of me doing the speedtest and hopping was iplayer got really bad.  Also I can see on my tbb graph now I checked that latency was getting quite high and then recovered with the hop. (remember my svlan is blue).

I've added two wireshark captures to the ticket. The first with IPv6 enabled, the second with it disabled.

While I'm sure Jelv's observations on IPv4/IPv6 Microsoft Lync are probably very interesting and relevant to his issue,  but those Wireshark traces are unlikely explain why his SamKnows whitebox graph of download speed tests has deteriorated recently when 'Chris' states that Jelv's connection VP is GREEN and there are no capacity issues.  If the exchange is not the problem and something else that is not 'Lync' protocol related is going on, then the 'Lync' stuff might be a red-herring ?,  and is likely to be a symptom rather than the cause.

Jelv's SamKnows whitebox download speed test results -

[#14]

It's definitely a symptom - I raised this to say how it is affecting me.
I've just searched the service status archive - the last announcement of increased capacity was last July (June for 20CN which I am on).
My gut feeling is that we are back in the bad old days of Plusnet not having enough capacity. The rate at which they've been installing FTTC connections we should have been seeing regular announcements.

[#15]

If Plusnet were running close to the limits of capacity (whether backhaul or gateway throughput), wouldn't we expect to see a flattening (or clipping) at the top of the aggregated traffic graphs during peak times ?
