ZEN Peak hours JITTER on BQM

As title says, i have been noticing some peak time jitter levels on the BQM doesn't appear thus far to be through put impacting, but it really should not be there, IMO, any other Zen FTTC customers seeing similar? on Zen's GEA network.

UPDATE it is NOW SERVICE AFFECTING SINGLE THREAD IS 50% of what I PAY for OVERLOADED MANCHESTER LINKS !!!!!!!!!!! PEAK TIME BS IS NOT WHAT ZEN SHOULD SUPPLY.This IS NOT GOOD ENOUGH ZEN

Jitter is the difference or variation in round trip delay between successive packets going to the same destination from the same source. Think of it as cars in different lanes which set off at the same time, but arrive at different times. Large jitter values aren’t great for ‘real time’ systems which need predictable delay. Like voice communication over the internet. For other stuff it’s less important.

I don’t think you’re actually talking about jitter.

For a start jitter is not noted / measured, that I’m aware of, in the TBB speed tester. See your own screenshot link. No mention of jitter. Some other speed testers do measure jitter for the record however. Jitter is also not noted on the BQM test results. The measures there are ping time (min, average and max) and packet loss. Not jitter.

So if not jitter what exactly is your complaint about?

To me it is Always A 1st sign of overloaded linx, And when single threaded throughput dives or fluctuates on many source servers that is evident of PILE EM HIGH ,SELL EM CHEAP That even ISP'S LIKE ZEN SADLY HAVE SUCCUMBED TO, NOT ACCEPTABLE for a “PREMIER ISP” imo

We’re still not talking about actual “jitter” though.

What’s your actual BQM look like? Post a link to your live BQM please.

Are you seeing large variations in your speed tests? If so that’s NOT jitter, that could be congestion. But let’s see the BQM

TODAY

The red is ME trying to get onto a UNCONGESTED GATEWAY, but they have blocked access to London, SO I HAVE NO REAL CHOICE , [censored] IMO

Looks like some peak time congestion going on that graph, around 7:30 to 8 pm. However you said you were trying to shift gateways.

Is it the same each evening? If so have you discussed with them?

oddly NOT every evening, BUT it is PROGRESSIVELY heading that way (becoming more FREQUENT) Was a month ago WEEK ENDS, Now extending into week days, Mr Tang maybe is being undermined, or he is sanctioning this [censored]

If you're unhappy with the Zen service and believe something needs to be fixed (either to the Openreach bit or to the Zen backhaul) then its best to raise it with them as they are the only ones who can look into it for you and if necessary do something about it.

Yes i know, but i was interested to know if there were others Who were AWARE of the is degradation f service during peak hours, Other than me, Because if the masses have no clue why would they listen to 1 man or woman?

In the absence of BOLD TYPE FONTS, HOW else do you expect people to emphasise their issues? I aint SHOUTING at anyone [censored]

Apart from the period when you where trying to shift gateways I can't see a lot wrong with that graph.

I said it because you started a thread called "Pstn line fault" on the 4th February 2025 (less than 3 weeks ago), so you seem generally unhappy with your broadband. See the content of that thread below

Today My FFTC 80/20 service was reduced to Less than 50% sync was Full for both up and down, now 37.5mbps and the upload is 12 meg, My phone line has no dial tone, But i can ring it, but no ringer,, number is registered on display calls cannot be made not that you could hear anything if they could, Reported to the Phone suppliers and received a text from OR saying their tests suggest the fault is outside my property, Give em a clap, One of their staff or the subcontracted idiots has CAUSED the fault , buy disconnecting one leg of my Pair At the PCPmost likley

The same thing Happened last year around this time of the year , but i was in hospital then, but the stats program captured the same thing, switching from 80/20 to 40/10 and back several times of a a few weeks

Not true, lots of options- https://forums.thinkbroadband.com/faq_english.php#html

Plenty of ways as has been pointed out. However you really need to calm down. You're coming across like some spoilt brat sat in a basement throwing his toys around because things aren't as perfect as you'd like. People are struggling to take you seriously as a result.

Calm down!

It's a residential service and that means best efforts so at times things will go wrong. you have to understand and accept that. Be polite. Describe the problem accurately (something you have still failed to do) and then wait.

You're acting as if your life is in danger and it's the end of the world. It's very hard for anyone to take you seriously when you're doing that.

The problem was lower and fluctuating throughput, during peak time, Something that Shouldn't be happening, and is a result of over loading their network, The jitter on the graph is a visible sign of this happening, Usually a lot worse when you see the hump effect or packet loss too Which I would expect on BT WMC or what ever they call it, But not on an ISP's own network as they should be monitoring things as it is in their control, This clearly ain't happening

And when they prevent you from hopping on to London gateways, it gets frustrating, As for the other issue that was caused outside the ISP control i was not blaming them, but BT open reach or their subbies

Try this tool from Cloudflare. It will show you;

At the end it will give you an overall network score for different scenarios such as gaming etc
Please wait till completed and should take a couple of minutes.

Slight peak time congestion is going to have to be something that residential customers get used to, an ISP cannot operate multigig broadband services and have the onward capacity for everybody to hit 90%+ of their headline rate on a single connection.

The bulk of high throughput activities are multi-threaded, speedtests or IPsec tunnels are really the only things left that shift a lot of data around and use single connections.

So you look at BQM for no reason, saw a discrepancy and started speed testing. Nothing wrong with your service in use, you saw an issue on an artificial test and started running more artificial tests and are complaining as they aren't where you think they should be.

Read that back and think about it.
