One potential problem you will undoubtably run into is when the box this script is running on looses access to the Internet... you'll get 1000 false positives.

It would probably be better for your script to keep some type of history and only report a failure after 5 days of failure.

Also, the script should be self-checking in some way (like checking a known good web site [google?]) before continuing with the standard checks.
