As a sense of the Japanese, it is hardly supposed that the system that is in operation, especially online system, will go down during the daytime. It is quite common sense that services are always provided at the time we want to use and it is a service provider’s problem if the system cannot be used even for any reason. Especially we think that it is essential that the Internet can be used 24 hours a day, 365 days a year, 24 x7.
Also, even for real stores, as the number of stores with no holidays throughout the year is increasing recently, so it is very disappointing if the store we want to go is closed. I think that it is because we consider only our own convenience and do not care much about the circumstances of the service provider on the other hand.
