  From china to usa..
  what type of WAN topology is in use?

  Physically, I can't tell.
  
  Logically, I would think it's a bus.

  i don't think its a bus. if the main line goes down, that's it.
  
  i think physically it might be a mesh, its expensive, but a good investment

  could it be star-bus? star topology at each end point, bus for connecting between china to usa.

  You are right, but I get a feeling that they might just do it to save costs.
  
  A mesh is too hard to troubleshoot... a combination of two different kinds might be the best for now...

  And I've forgotten one question - physical or logical topology or both that you are trying to seek?
  
  Before seeking answers, do you understand the different topologies first?

  maybe a multiple bus? like maybe have a bus, but another bus as a failsafe? in case one goes down?
  
  i remember there was a case right? taiwan or hongkong? some drillers accidentally hit into a wire, and caused the internet to go down in flames

  Multiple bus is possible.

  *raise up hand*
  
  why multiple bus and not mesh?
  
  a multiple bus = mesh yes?

  You can consider it to be one if it creates redundant connections to other network devices. Mesh topology purpose is create redundancy so that if one node goes down, the others will still be working and traffic will be re-routed.

  hmm..
  physical.
  not really interested in logically for now.
  
  hmmm...
  as for the thing about the taiwan drill..
  what really happen huh??

  For WAN, it's preferably that one use use mesh. Otherwise, if any node breaks, you risk the whole network going down.
