Has Linux got tools that can run while a computer runs that can poll
several sites and log internet outages?  I figure a minute down time is a
failure and have experienced several of these where my wifi connection
had
to be deactivated and reactivated to have the internet connection
restored.  This is a new wifi router too.  The log would be sent into
comcast along with payment requesting credits for the down times.

I suggest:

1.  Test and verify your network cables:

2.  Buy and read "Networking for System Administrators" by Lucas:

3.  Write a shell script that invokes some standard utility (ping(8),
wget(1), etc.), appends a timestamp and the utility output to a log
file, sleeps for 60 seconds, and then repeats.  >

Along with redirecting the output to a file, the logger(1) utility can
also be used (1) to make entry in the system log.

Yes -- that would be a possible follow-on exercise to #3. Also see rsyslog(8) and rsyslog.conf(5).
