No application should ever use IPs (well, I'm sure there are cases, but
99.99999% shouldn't). That's one of my pet peaves and I deal with it every
day with customers using our software. :)

No host table entries either! Use the DNS and host names!

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.
