I would like to get a list of all active servers (JobID's) via script is that somehow possible?
There is no endpoint and no actual way to get a list of servers. ROBLOX specifically changed the server layout to stop users from scraping and getting all the servers.
As someone commented, you may be able to create a cross-server data store to store all data stores or you can send it all to a database off of ROBLOX which may make it easier to access.
