What is the sudden upgrade of Hangzhou Bank's online banking?

A: Bank upgrade usually refers to the optimization and upgrade of the back-office system, adding some new functions, which has nothing to do with users.

However, during the upgrade and maintenance period, the bank card will be temporarily unavailable, so banks will generally send text messages or announcements to inform customers, but it will not cause too much inconvenience to users, because bank upgrades are generally around 0: 00.
