Ansible in my experience will stop trying to run subsequent tasks on a server once one of them fails, but it will go ahead with other servers that match the inventory pattern. So it very well could have successfully updated 7 out of 8 hosts.
Maybe there is a switch that will stop everything if any task on any host fails but it's not the default behavior.
At least it would have logged an error that hopefully would have been looked at.
