so i have been told. i do not know how long the lease is, but i do know
that it is longer than 30 days. i used to have dsl modem power brick
plugged in wall outlet. i realized my error a good while back when i
lost mains and i was downloading a large file and had about 10 minutes
remaining.

if i had brick plugged into ups, i could have halted dl and resumed when
mains can back up. it was not a torrent. :-(

i did correct my error. now, from time to time when i 'pull plugs', i get
a new ip and really not concerned how long i hold ip.

now, sometimes i pull dsl line just to refresh ip and avoid 'crazies'
hacking ip blocks.

not a problem.

first jump is run to a rather large cabinet at side of a street, about
8 blocks away, where it goes from copper to fiber. then connects to a
'central office' about 5 miles away. what is in between me and 'co',
i have no idea. [see attached for a tracerute]


when i first signed up with aDSL, i did not get speed i am paying for,
so i call at&t to have a check run to see what/where problem was.

as it turns out, i am at end of a run, approx 3k20 feet of copper. :-(
so instead of 138 kbps, i average around 86 kbps.

fiber is in my future.
