I don't understand what has happen? After 27 days stable of 79999/19999 as it now reduced at 46147/19664 (why?)

I noticed downstream SNR shoot up from 6.1dB to 14.8dB and line attenuation went from 11.7dB to 14.7dB
I haven't touch anything?

Reboot it matey

It resync itself again *2 times now*

Something is not right!
SNR kept jump to 15dB and next is drop to 2dB
Lots of errors now. DLM could capped the line tomorrow ???
-
Have there been any thunderstorms in the Telford area recently?
-
Nope it been dry all day today and all this evening with clear skies
-
Resync again 3rd times!

I don't like the look of the SNRM plot and the number of ES (& SES) are significant. I wonder if the recent hot weather is somehow involved. :-\

after 10th resync the line seem stable now for 10 minutes but too late now as DLM will bite my line to be banded next 24 hours! :no:

Do u think I should inform Plusnet of this caused my line resync 10th time but it seem stable now after 34 minutes no SNR drop or no errors but I don't know what is caused this. Hope DLM isn't thinking ok we will put his line banded don't like 300 errors in the last 30 mins bin time.
My bin cupboard always on cold side the front always cold (no sun can reach my bin cupboard where the DSL cable there) or is it to do with my fibre cabinet burning up or telephone exchange issues?
After 10th resync the worse SNR drop I ever seen is -0.4dB and connection rate at 18765Kbps. with nearly 300 errors second in the space of 30 minutes on the downstream but all day today was zero errored

My bin cupboard always on cold side the front always cold (no sun can reach my bin cupboard where the DSL cable there) or is it to do with my fibre cabinet burning up or telephone exchange issues?
Any problem with the metallic pathway which is affecting the broadband service can only be that length between the VTU-C (the cabinet based DSLAM) and the VTU-R (your modem/router). I.e. the D-side.
The cabinets can get very hot at this time of the year but they are designed to be able to cope with elevated temperatures.
Just looking at the SNRM plot makes me suspicious that there could be a joint that is going defective. Possibly showing HR or semi-conductive tendencies.
-
Did you check the voice line during the poor performance to see if it was crackling/noisy?
That should pretty much always be the first thing you check when such a severe change like this occurs.
-
No, the line was perfectly silent on 17070 option 2 as I did that
-
Updated:
I just went to the bin cupboard to have a quick look but I have to closed it quickly with a shocked to my face as there is swarm of bees there

updated: stable ongoing for 12 hours (no DLM action or banded on the line yet so far) finger cross it won't happen now! :fingers:

That's good to know. :)
I presume that you caused the circuit re-train, showing as "(since 09 Aug 2020 10:26:10)", just before harvesting the statistics "Stats recorded 09 Aug 2020 10:29:14".

Yes that's because I resetted errors via billions router as I haven't rebooted or touch the billions router at all. The router did crazy resync 10th times and that was it. Still stable for 16 hours now. PN current line does reduced from 78Mb to 18Mb even though BTW bras ip profile still at 77.35Mb. So, I just make sure I don't do PPPOE soft disconnected otherwise the speed will be limit at 18Mb because of PN current line speed but hope PN didn't kick in with 18Mb.

It's still in the cupboard. Beekeepers say it a bumblebees and told me to leave it alone, it will go away in September. Just showed them Broseley Beeskeeper of that video of bees in cupboard.

Makes sense, bumblebees are endangered!

Do u think DLM has working very well this time will ingorne terrible 10th resync in 24 hours ago. I was amused by this because I would thought DLM will trigger banded on my line today but it didn't happen! Thanks goodness for this!
