Abstract
Information update technique where information held by every apparatus does not need to be updated at the same time. A first server is connected with a second server. The first server judges whether it is possible to access the second server. When a result of the judgment shows that the second server may be accessed, then the first server sends an information update request including information to the second server. On the other hand, when the result of the judgment shows that it is impossible to access the second server, the first server repeats the judgment until it becomes possible to access the second server. When it becomes possible to access the second server, the first server sends an information update request including the information to the second server. Receiving the information update request, the second server updates its information by replacing the information with new information, i.e. the information included in the information update request.
