Telepocalypse has an interesting article about when it’s dumb to be stupid.

This was observed and codified by some smart people at Sun over a decade ago as the Eight Fallacies of Networking.
1. The network is reliable.
2. Latency is zero.
3. Bandwidth is infinite.
4. The network is secure.
5. Topology doesn’t change.
6. There is one administrator.
7. Transport cost is zero.
8. The network is homogeneous.

Interesting read, except it is important not to confuse “stupid” here with Stupid Network. One is saying you should not trust the network too much whereas the other is saying the design of the network should not interfer with the applications.
