I haven't had a land line here for a decade or more. The storm didn't take down the local power lines. But we loose electric service a lot in bad weather. The only time I recall things being very bad was a storm (remnant of a hurricane) that did take down the local power lines. This happened everywhere of course so it was a week or so before power was restored and I'm sure land lines too. -- Rick

It figures when you think about it: small diameter telephone wires that
can be strung rather tighter between the poles than power lines. That
means the wire won't thrash around so much in the wind. Being smaller
diameter the drag, and the resulting wind load on the wires will be less.
But the wires are still relatively thick compared with insulated copper,
so power will most likely still get to subscriber kit even if the wires
get damaged but not actually broken. Last but not least, even if poles
move so the wires get slack enough to touch and give momentary shorts,
the voltage is low enough that this won't break the wires.

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.

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. -- from Tim Hill who welcomes incoming email to tim at timil dot com. * Share in a better energy supplier: http://tjrh.eu/coopnrg * Share in cheaper ethical telecoms: http://tjrh.eu/phone * Have a genuine & spam-proof address for Usenet http://www.invalid.org.uk/

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.

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.

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)

(I assume the US use 911 so that the 2nd & > 3rd digits can be dialled faster) When I heard of 999 in the UK, I wondered about our 911. I didn't think pulse dialing was still widely used by the time 911 came in, but looking it up I see this was the late 60's and pulse dialing was still in widespread use. I know that three digit numbers with a 0 or 1 in the middle were used as area codes and all equipment recognized them as special. AT&T was already using 411 and 611 for information and support, so I guess 911 seemed the easiest to implement and least likely to cause problems with mis-dials... except they didn't factor in the use of 9 to get an outside line through a PBX and the use of 1 to obtain long distance. We had a fax machine that somehow would dial up the emergency center from time to time by mistake. It got the wrong kind of attention and was disconnected. -- Rick
