Site stuck during provisioning ?

Hi All, 

yesterday I installed the site with secure mesh and after some time the site got stuck in provisioning state, when I run some commands to see the status of the site and it shows below mentioned output 

"status ver" : "The service is being restarted" 

"config-network" : "The site is in provisioning state"

Moreover the ssh and https access to the site was also lost and "health" command is also not showing any IP address configured, rebooted the site and nothing works. When checked the main console it shows like the site is being upgraded. Waited for 2 to 3 hours no difference. Also checked the F5 Zendesk document but couldn't able to relate to my situation.  Left the site overnight and in the morning just rebooted the site and it actually provisioned. I observed the similar behavior during the F5 lab when the site was upgraded. it took atleast 6 to 7 hours of to upgrade and then the after the manual reboot the site got working. I just wana know is it a default behavior or am I missed something ?
