Am I being paranoid?

For the last six months or more my FTTC has synced Rock Solid at 70/20, Always, no change, 70/20, full stop.

Now my contact is up, two weeks ago, I started to investigate switching services.

So, on my travels to get quotes and estimated speeds, entering that particular phone number etc. I have always had quotes of up to 66 or 67 Mbp/s.No problem with that, as they now have to do a more accurate mean or average speed etc...

From that day onward, my current sync has been slowing falling a little Tiny bit every day, day by day from 70/20 to a now 67.7/20 currently.

It's slowly sliding down, and i'm awaiting for it to settle yet still.

Has this happened because I have investigated what service are available, of which the estimates are less than what I am already getting are available? OR Is my current ISP slowing down?
Am I Just being paranoid?

Yes, yes you are.

Thank goodness for that

P.S. Otherwise, I just done the maths and I could be down to 7 Mbps when the Brexit negotiations are over...

The problem with FTTC, in its current form, is that the more popular it becomes the slower speed people will get on the cabinet.

I started at about 78/20 and now I'm at 54/16.

Its the cross talk causing it.

G.Fast for example really suffers due to the higher signal frequencies involved.

Its my opinion but the dislike of the DLM system and people wanting theirs reset all the time has delayed or even halted the implementation of vectoring. That's why Openreach have now moved focus to FTTP.

G.fast isn't crosstalk suffers. Only the FTTC - yes.

The sun may have gone out by the time negotiations are over...

AIUI vectoring is mandatory in G.Fast implementations. It�s part of the specification.

And on ADSL2+ im getting faster speeds than before because people are moving to Fibre

Well, to me, unless I am being paranoid, there is a Gremlin in the works.

Maybe the Gremlin is set work if you are looking to change to a another provider that has a lower estimate than you already have........

I've checked with my alter ego, but she's not sure

It would be pretty silly for a company to slow down people just before they are eligible to leave, and for what ends?

Like people above have said it could be cross talk. But, it also could be the weather, it could have been a power interruption, it could be a firmware �upgrade�, or it could just be the usual fluctuations when re-syncing.

This is an openreach gremlin... I heard this strange noise last week and he was putting his ladders on the top of his Transit van...

You've lost 2.2 mbps and how is that impacting on your day to day internet use?

edit: to clarify - only 3% reduction in a fast connection.

It's all relative.

If I lost 2.2Mbps it would be a problem, I've only got 1.8 to start with.

See above edit.

+1 same here.

None at all

It's just strange that it started to drop the day after I started enquiring online to switch & being given quotes of up to 67 on this line. It was at a rock solid 70 since Easter before that.
It has now settled at 67 and stopped dropping.
Seems a bit of a coincidence.

So it makes me wonder, would it of stayed at 70 if I hadn't made online enquiries about switching.

Think about it for more than 1 second. Why would an offline database from other companies other than your supplier have any effect on your line. It�s madness to think there is any link whatsoever. As has been pointed out more than once it is highly likely someone who has a phone line in close proximity to your line in the cable bundle back to the drop point or cabinet has connected to FTTC. This cross talk interference then dropped your line speed slightly.

This is no Moulder & Scully moment, not is it a group of people in a smokey back room doing untoward things.

Why on earth would your ISP reduce your speed if you were thinking of leaving? It would only reinforce your resolve.

Yes, you are being paranoid. There's a lot of it about.

Do they all use offline databases of their own?

I thought they might have used the openreach database live online to get their estimates.
Maybe i guessed wrong though.

I might of been drunk when I wrote that part about my isp

I can't remember what I meant there hahahaha

Oh! I remember now! I was probably thinking at the time, maybe after getting those max 67 speed estimates, the live database sent a signal to the DLM on my cabinet to slow it down to 67.......

The more likely scenario here is your line check was reporting what your line should have been syncing at based on the current stats, but if it hadn't resynced in a while you would still be connected at what it previously could handle before the crosstalk you are now subjected to.

Particularly if you are on an ECI cabinet, DLM wont allow you to sync lower than 6dB SNR, your line had probably drifting below this so the re-sync meant your speed reduced.

Over the last couple of years my own line has slowly reduced from 79Mbit to 66Mbit. That's just the way it is with more and more people getting VDSL. I know around here there used to be a lot of mobile hotspots, as they have changed into Sky and Talk Talk, my speed reduced, showing the clear indication of what caused the extra crosstalk.

That's interesting! I am on an ECI cabinet with 6dB SNR Margin.

Before I went on holiday last Easter my sync speed was 80/20 with 3dB SNR Margin. could this mean I could of been on a different cabinet then?

I've always suspected they changed my connection from a cabinet that is 250 metres away to the one that is now 450 metres away, while I was on holiday.

That's about as likely as the moon being made of blue cheese. Quit obsessing about this and accept that speeds are going to change over time and for the most part downwards until such time as your neighbours have moved to FTTP or 5G.

Yes indeed, it seems unlikely.
So I take it it is possible to get 80/20 sync from an ECI cabinet that's 450 metres away?
(cabinet doesn't have G.IMP or vectoring enabled.)
