 There are two partially difficult problems in computer science:

 ## Why we use it
-{Details of how the config was ascattered and hard to find}  
-{Also embracing devops and reduced manpower}
+Back in [January 2023 we got disconnected from teh internet][skynet_disconnect].  
+For the purposes of this document the root cause is not of importance.
+What *is* the mad Indian Jones ~~treasure~~ config hunt that it triggered.   
+![Brendan delving for configs][skynet_disconnect_reenactment]  
+Additionally ITD require us to update our systems regularly (as they should be).  
+Technically this config delving is an ongoing effort, the old hard drives are occasionally connected up and raided.
+
+As you would imagine this is not ideal, a exasperating factor was that many programs had changed both the location and format of their configuration over the decades that Skynet has been using them.  
+
+This is where teh strengths of NixOS lie.  
+The config for the entire cluster is located in a singular location.  
+Using modules which work as a translation layer if the requirements for the programs change this dont impact us.  
+Not to mention we can fearlessly (and regularly) update our systems it is a match made is heaven.  
+
+Currently the Skynet cluster is comprised of 15 servers which have NixOS on them.  
+A combination of LXC's (Linux Containers) and physical bare metal servers.   
+Since these systems share a base config (with tehir individual applications layered on top) we are able to efficiently build them, building a package for one will also built it for other servers.  
+Combine that with teh ability to deploy them via our own selfhosted CI/CD we have a strong foundation to work off of.
