Cant reproduce on the environment provided by Ido.

Attached a small video on network topology while deleting 3 subnets.


What I did found on the environment provided before the actual one was that due to some error on cinder (which returned the exact error provided in the bug description[0]) the network topology keep reloading due to obtaining that error instead of the usual updated json on each ajax request.

This could easily affect the action of deleting a subnet, especially on a high latency environment in which the delete action takes time to execute, the ajax update for the network topology seemed to cause page issues which lead to the action never taking place in the first time (network calls returned the error at the top).

So this could be a problem that arises only when the openstack components are wrongly configured or malfunctioning.
