I am looking for ideas and suggestions that would follow the "Jira" way to store Vendor/site information. My client has quite a few satellite locations. These are small sites with their own ISPs, vendor contacts with some information. Very generic and varies from site to site. How would you go about storing this info? So if a call comes in that site 123 is experiencing internet issues, the tech agents of Jira SD would be able to find information about that site.
Here is an example:
Site 123
Curious Citizen
Address
Router is stored in closet 123 and here is the configuration info.
Thoughts? Clear as mud? 
Thank you for taking the time to reply
