Content whose own service has ended

Some content providers store separate data or operate their own servers for online services. However, over time, there are cases where the service cannot be maintained and is terminated.

For content that requires connection to a server, continuous operation is required to provide the server again, rather than simply modifying the relevant files. However, the server code and files required for server operation must be secured, and maintenance must be performed to prevent service errors, so content restoration may not be realistically possible.
