If the net is disconnected then poff may fail with "no pppd running"
which would cause poweroff to not be run. so

pon ntl && sleep 35 && apt-get update && apt-get dist-upgrade -dy ; poff ; poweroff

&& when you want the command to be run only when the first one succeeds.
|| when you want the second run if the first fails
; when you want it run regardless
