If the main network is not maintained, then the reliability of the entire network will be compromised, as a single unreliable node can bring down the entire network. This can result in significant financial losses for the organizations relying on this network. Additionally, it would also result in a poor user experience, which could lead to a decrease in the usage of the network and a reduction in revenue for the companies involved. Therefore, it is important that the main network is maintained to ensure the reliability and stability of the entire network.
