First of all, I've found DSL to be pretty reliable. I've had a few
downtimes in the past, but nothing significant. Of course, this depends on
your ISP/telco mix. Anyway, if you need something that tests your
conectivity for you, try this:

#!/bin/sh
LOG="/var/netlog"  # plug  what you want the logfile to be in here
ENDPT=""   # location to ping -- you could use yahoo or whatever you
           # want, but use an IP addr if possible

while true
do
	ping -c1 $ENDPT 2>/dev/null 1>&2
	[ $? -ne 0 ] && {
		echo "unable to reach network at `date`" >> $LOG
	}
done

hope that helps
