I posted here a while back that I had an issue with the VDSL slowing down over time.

When first installed , i was getting 30/8 , it eventually degraded to a third of that over months

A couple of days after posting, powering off the modem etc, there was no change

then...that night a thunderstorm appeared ... there were some good lightening nearby... VDSL was dropped and reconnected and I was back to 30/8...... no reset or power loss to router

Now the chorus cabinet is about 1km away.

So I was wondering....

Did the lightening cause equipment failure an there was a failover in the cabinet to other equipment

Could it of vaporized any "water" in the copper line and cause a better connection?

Reason I ask is I am now back to 12/16.... and have been for days......

and there has been no rain (until tonight)

Flick me a DM with your details, i'll take a peep.

Looks like something has gotten damaged at a skim though.

Is your router connected to a UPS? The thunderstorm might have knocked out the power to everyone else on that Cabinet. And you then get a much better sync rate, due to no interference from the other lines in the same cable.

Maybe the thunderstorm caused everyone's lines to resync at the same time. Which might have allowed some lines to resync with vectoring enabled, that were not previously vectored.

No ups.

Just to be clear:

Thunderstorm scenario was months ago

In present day, have not had rain for months.

realized download link speed was so slow, which made me think about last time.
