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). ---> Phil - - - - - - - - - - - - - - - - -
