What makes this monitor a bit more difficult is that the entire Internet was not down, only part of it.
Our other sites that use the Internet outside of the Level 3 territory were not impacted.

The other interesting thing with this URL, (by the way, TSYS is the authorizer.)
TSYS can change an IP, take one out of service, etc.
This is why the CC system only uses the URL, and not any of the IPs.

What about using GETURI or HTTPAPI to make a simple request to google.com, yahoo.com, etc. check the HTTP status code upon return, or monitor for failures.

If you run web servers on your system, you could check from the outside in using something like uptime robot (which is free for a few systems).

Could you write a small program that periodically "pings" each IP and
check its status?

On Friday morning, Level3 had a major outage, which in turn was
causing intermittent failures for our Curbstone credit card system
which runs on our i5.
It was 4 hours before we were notified that Level3 was the source of
the issue and no problem of ours.

s/ ?utm_source=twitterfeed&utm_medium=twitter

Curbstone uses a URL, which rotates to any one of 6 ips, spread
across the US.
When the IP was used that was in the Level3 outage area is when we
noticed intermittent failures.

Thank You
