Such topology is called star.

Star Topology WAN
A star topology.
A network star topology has all the clients connect to a central device, such as a hub or switch. The clients look like points of a star, hence the term star topology.
Star topology
The three most commonly used wide area network (WAN) topologies are point-to-point, hub-and-spoke, and mesh. In a point-to-point topology, a direct connection is established between two locations, providing a simple and efficient link. The hub-and-spoke model connects multiple remote sites to a central hub, facilitating easier management and data flow. Mesh topology involves interconnecting multiple nodes directly, allowing for redundancy and resilience, as each node can communicate with multiple others.
No, there is not.
A star topology; a network topology in which endpoints on a network are connected to a common central device by point-to-point links.
It is called a Star topology
In a star topology only the failed system would have a problem, unless the device was the network connectivity device (on a LAN).In a WAN, if the building was connected through the central building and the central building had a problem then all buildings would be affected. If it isn't the central connection point then only the building with the problem would be affected.
