Just had a look at MWS your crc's and es's seem to have got worse in the last 24 hours.

they were good at first

but its been a lot of rain and I think is killing the line.

I went upstairs and looked at junction box and is filled with water, no lid on it.

The same junction box that has never been checked since years ago.

This I can't get my head around with the SSFP MK2 inplace the US errored seconds becomes more noticeable with a loss of US attainable in the stats during the day time and with the SSFP MK1 inplace there is less US errored seconds and more US attainable 24/7

Beginning at 0 Hz and moving upwards to higher frequencies, first we see the (audio) frequency band of the telephone service then next comes the xDSL US frequency band.

If the low-pass filter of the Mk 2 is "less precise" then the low-pass filter of the Mk 1 then perhaps the upper reaches of the telephony band manage to "escape" into the "bottom" end of the xDSL US band?  :-\  Or perhaps not . . .

So this is normal then ?

No. I wouldn't think so.

What you really need is the loan of a spectrum analyser so that you could compare the behaviour of each SSFP.

Please no more tech equipment i'll have my hands full next week when the RPi arrives it's got a 8GB Noobs card, the last time I saw that word was when running World of Warplanes and the other team called us Noobs  :D

Be careful - Raspberry Pis are like cats.  I got one in 2012, and now I have 4, thinking of getting a fifth.  They multiply!

Yes cat's are loveable pets until they don't come back for whatever reason lost 2 cats in the space of 8 weeks it breaks your heart.

Think I'll stick with just the one RPi and our last cat my avatar Ceaser he's more like dog than a cat always beside me.

Could you take a picture and show us this junction box please ?? I've never known overhead JB's fill with water.

For info .. we don't go round randomly checking DP's/JB's that would be madness. We are tasked with resolving the issue, only if we are working actually on the plant itself. If we aren't working on the plant, but espy defective issues whilst passing, we can input an A1024 for remedial work to be carried out.
Or .. as someone who monitors there broadband line every day, you yourself could ring Openreach and raise an issue ??. This will see any defect get resolved a lot quicker.

Well i had to go in my neighbour's flat, I dont have free access. I was in there doing something for her, and had a look then.

But will try to take a pic.  It is possible I guess there is a lid thats below the edges of the box and the water was on top of that.

If you (as a friend and neighbour) don't have "Free access", then the chances of us checking is going to be limited to say the least ??

"It is possible I guess there is a lid that's below the edges of the box and the water was on top of that".

Anybody that owns a premises, let alone a million-plus jointing points, will appreciate that halting the ingress of water is nigh-on impossible, especially in underground enclosures. If it's above ground, then none of the closures are waterproof, as the water will drain by the laws of gravity, for that reason there is no "Edge of boxes".
They do have a certain level of 'splash' protection afforded to them (Equivalent, I would imagine, to the electrical regs IP index), but nothing else is required due to the afore-mentioned laws of gravity.
