> A network where all nodes are fully connected to every other node and data can be routed through secondary indirect paths if the primary direct path fails is absolutely a mesh network.
Yes, that is a classical partially connected mesh because it functions without a direct connection between all nodes. That you started out fully connected does not matter.
If the network relies on direct connection between source and destination, it is not a mesh.
> And a 3 node ring is absolutely still a ring network.
Only if it can route when you break the loop, and only if you extend it by inserting more nodes into the ring.
The example in this article does not route, which is why it is absolutely not a ring - If you disconnect server A and B, they cannot talk even if they both connect to C. There are just 3 entirely independent point to point networks.
