Karl,

How do you handle hardware upgrades, random crashes, etc. with your
clients?  Do you give them a refund for such downtimes?  DO you guarentee
that every client that tries to access their web page will always get
through?  

My guess is you don't.  You perform a service for them and probably
schedule maintenence in such a way as to minimize downtime and impact on
that service.  

If you have a better scheme, like fully redundent machines that fall over
automatically and let you do maintenence on one while the other opperates
then I think you have done an excellent job at providing a quality service
for your customers.  On the other hand, someone who has done such a setup
should realize how easy it would be to migrate it to different addresses
while maintaining pretty much complete connectivity for the old addresses
for a reasonable time (like a standard TTL length).
