Corruption in sharepoint 2013

Question

We have a share point 2013 farm with 2 nodes.  There are 64 web applications in one node.  2 weeks back when we tried to create another HNSC web application it corrupted the whole system and all our sites were down.  We had to restore back the entire machine to get it to work.  

 

Has anybody faced this issue before?  If so what is the root cause for this and remedy.

 

Thanks in advance for any help
