Cat's Sandbox

Cat's Sandbox was a server that existed back then. (Need someone who remembers the date on which the server operated) ULSCI operated on Cat's Sandbox (1-47 came later and encountered ULSCI, where they had a brief conflict, later beginning a long historical alliance)

(D-BOI-9341: Ally For Hire once recorded footage of a battle on Cat's Sandbox between 1-47/NATO and IZK/Petrograd?)
