You decide how to use that service. If you buy a software package elsewhere, it is up to you and the software's creator to figure out how it works. Xcalibur's Role in Providing Your Connection As your ISP, Xcalibur is required to provide a live Internet connection whenever possible. The machine must be shut down periodically for maintenance and upgrade tasks. We will make every attempt to announce planned shutdowns before they happen.
Unplanned shutdowns are beyond our control.
When the system crashes, our technicians are right there to begin working on the problem and get the system back up as quickly as possible. This happens to all ISPs - some more often than others. The most famous was the America Online crash of 1996, during which the entire America Online network shut down for more than a day. Xcalibur has a good track record in terms of the number of unplanned shutdowns and the length of time before the system is restored. We intend to keep that good record in the future.
