When I put the Internet into Guernsey, they proudly showed me the acre and a half of underground diesel tanks and the 3 large diesel generating sets that would keep the phones going on the island for 10 days even if the main power station failed and they were utterly cut off from the mainland.
That's APART from the batteries..

Dunno about the US but all phone lines in the UK are insulated multi-stranded twisted pairs.
Even the ones up poles.
In fact a storm brought down a pole locally, and it stayed down with the wires still attached for several weeks. The phones carried on working...

So how does my phone reach those batteries in the exchanges when the wire has ripped in two from the poles lying on the ground?

None of that helps when a tree falls on the line ripping it in half with a hundred pairs of wires splayed across the ground.

As I pointed out, even the pole lying on the ground doesn't rip the wires in two in many cases

I've never seen that happen. Poles down yes, wires snapped in half - no. 100 pair cables are dam,ned tough
I've seen an overhead pair take a direct lightning strike though,. Outside my house. Fortunately I wasn't at home as the place was littered with exploded sockets and lord knows what else
Fried a lot of electronics too
House had to be rewired.

Dunno about your part of the UK, but here (and everywhere else I've been) the cables between the poles and the house tend to be two uninsulated cables, a few inches apart.

Over here in NL we have no poles at all, at least not the kind that holds power or phone cables for local distribution.

absolutely not ever round her.
generally two or 4 pair in a sheath with a steel inner.
You aren't confusing them with POWER cables carrying 240V are you?

Not even sure the London Underground still uses such a primitive system.
Nope. None in this UK street either: everything is underground. I know that my phone lines are underground all the five minute walk away to the exchange apart from the street cabinet in between.
P.S. What does this thread have to do with Flash on the Pi? I didn't see it start but guess it has drifted somewhat.

Certainly not. The power cables are all underground in this area. Actually my phone line is underground, but I'm in the newer part built in the 1980s. The houses built in the 1950s still have wires from poles. I used to live in one and I got a ladder and had a look at the phone cables one day.

When I was a wee small lad you used to see this a lot. Miles and miles of poles along the roadside with dozens of uninsulated pairs, but I can't remember the last time I saw them. Yes, I *am* that old :)

well yes, back in the 50s but every cable since abouut 1960 has bee twisted pair strengthened and usually multipair,
I think I last saw a porcelain insulated phone line sometime back in the 70s in Wales.

I suspect it relates to whether that section has been replaced since the introduction of sheathed pairs

this is why the UK emergency number is 999 if a pair of wires temporarily touches it can be seen as a pulse dialling. attempt. the chances of wind causing a correct pulse sequence for 999 is extremely unlikely. (I assume the US use 911 so that the 2nd & 3rd digits can be dialled faster)

They were hardly used here, but we have only weak soil where it is easy to dig.
However, I remember when I was a child we went on holidays to France with the family, and both power and telephone lines were overhead there. The old lines were individual wires on porcelain insulators, arranged in quads that rotated 90 degrees every few hundred meters, over the span of two poles. Interesting view when looking at it from a car going along the road. It was being replaced by multipair cable, so in areas that had been converted the poles carried one or two of those cables and the insulators still sat there unused. New poles of course did not have the insulators.
This is over 40 years ago, and I have been there for a long time.

Ahh! Memories of standing with an ear pressed against the pole listening to the wires 'music'. Memories of which inspired me to compose this:

Power loss can corrupt flash irretrievably. Use a UPS to prevent sudden power loss. Put everything on UPS so you can surf in a power outage. Won't the ISP be down if the power is down? A hurricane will take out the cables anyway. etc.

This thread was about Adobe Flash. You know, the product that (like other Adobe products) needs constant updating to solve vulnerabilities. In insecurity it is only surpassed by Java.
What does it have to do with power loss?
