Drop in DL and UL SNR

I was away for several weeks and when I came back and looked at my HG612 stats I noticed that the SNRs had dropped.
Previously, the DS and US SNR were both around 6dB (varied a little).
Now, the DS is around 5.3dB and the US is 4.4dB.
I do know that US G.Inp was switched off whilst I was away, but not sure if that has anything to do with it. US interleaving is now 1 (which I assume is fastpath).
Speeds don't seem affected.
My initial thought was crosstalk as the uptake of fibre in the area increased.
Does anyone have any additional thoughts?
Thanks in advance.
