After the upgrade to 9.1 nodes of the tree hosts levels of grouping is not showing all and when only a host of a map of the region is down the led this region is in the red instead of yellow like before.
Someone is having the same problem?
That is by design- see this thread for details-Re: Upgrade from 9.0 SP2 to 9.1 issue
As for the Support ticket- Netsuite has identified the issue as being related to non-us country codes and are trying to fix this as a top priority. Until then you might select US as a country now regardless of your country when submitting a ticket.
