may be bug
I have created a instance of virtual machine named 'ark-java8' for test.
after the test, I deleted it.
and I created another instance, and deleted it, too.
again, I create another instance, it's name is 'ark-test-kk'.
But its instance name is set to 'ark-java8' and DNS host name is 'ark-test-kk.cloudapp.net'.
It will be shown in a image attached. Left top is 'ark-java8' and Bottom right is 'ark-test-kk'.
I think it is bug.
with best regards,
