[AusNOG] Lightning and FTTC - is it really this bad?

As somebody who lives in one of the areas that gets affected a lot, and that the article was mostly written about I believe, I can tell you that there are a lot more NTD’s getting damaged than there was ADSL modems.
I can’t explain it either, it shouldn’t be happening, however people with surge protected power boards are copping it as well, it’s like it’s coming through the copper, maybe due to the nature of the DPU and other people connected, perhaps it’s transiting the DPU and damaging other NTD’s, I don’t know, but the DPU’s seem to be unaffected, only NTD’s, so it could be a design issue.
I don’t use NBN myself, however our local facebook page lights up whenever there is a storm approaching or upon us, with people talking about unplugging NTD’s etc. and then of course afterwards when people complain about no internet, and then the complaints that it’s taken NBN 5 days to get there and replace it 
Many people have been told by the provider that NBN is looking at NTD’s which handle power spikes better, I don’t know what they are actually doing but that’s what people are being told.
The NBN techs will also not leave spare equipment, this makes sense of course, but I know the question has been asked many times in our community.
I believe the article came about due to many people complaining to local MP’s about the issues and obviously the media has picked it up as well.

Damien, I agree with you.  Lightning is going to be causing the same issues it always caused regardless of the technology; telegram, POTS, ADSL or VDSL from the curb or cabinet – nothing’s changed because there’s still copper conductors in the ground.
I smell a lot of agenda pushing and bias in this article and that’s about all it is.
Although, maybe a more important topic mentioned in the article – NBN won’t allow these businesses to buy a cold spare?!?

Yeah it really didn’t make sense to me. How is a product which only has a TINY bit of copper compared to FTTN and indeed the older POTS network, SO much more susceptible to lightning strikes?  I mean, it’s Fibre to the pit, and then one breakout box is running four(?) homes, with maybe 100-150m total of copper between all four homes’ runs?  Unless lightning is hitting one of those houses, or the people in those houses are stupid enough to NOT be running surge protection on their gear (seriously, wtf? Are there really people without surge protection these days? It’s been around for 30 years, and is on almost every power board Bunnings sell..), I don’t see how lightning can be an issue??
Something doesn’t make sense here..

Yes Mark, I've heard of it ;)
I guess my point was - why is (is it?) FTTC somehow apparently more susceptible to discharge issues than POTS was/is. Perhaps I am getting the wrong impression from the article.

Heard of ADSL? POTS?
If the Internet was only meant to run over fibre, there wouldn't have been any ARPANET or Internet before the late 1980s or early 1990s.
Fun fact, RFC1 was written on a typewriter in a bathroom in 1969, because Steve didn't want to disturb his flatmates.
