Yes yes, I know it is me asking this question and I know there is numerous threads on here potentially asking the question I am asking but hear me out.

My Parents have got VDSL out in the middle of rural nowhere as you guys likely know. Well, I screwed up with doing some maintenance on their network while I am here and have had to reboot their router a few times. They also get almost weekly powercuts (a hassle for me since every time I have to re-image a Raspberry Pi that had corrupted itself).

Their normal sync looks like this:

But since these latest powercuts (around 6 in one day) along with me resetting the router it has dropped... When I arrived yesterday before touching it the router had a sync of 67Mbit down, 30Mbit up. Now it is 36/14. A pain for me since I come from Gigabit UFB.

I've raised a fault with Voyager to potentially get the DLM reset after I install a UPS on their networking equipment which they're doing but the question here is when does the DSLAM consider the line is potentially dodgy and how much time normally would it take for DLM to reset back to its normal profile?

Voyager btw have been incredibly good to deal with after explaining to them they get many powercuts but I must not be the only person in this situation. There will be others who have DLM decide their line is dodgy due to dodgy electricity especially out here.

Here is hoping Chorus actually reset the profile in the time I am here :)
