The network is a cluster of servers that share one character. Your inventory, skills, buffs, quests, vault and SurvivalCash all travel with you between servers — instantly and dupe-proof.

Traveling saves your character, releases the lock, and reconnects you on the destination — so nothing is ever in two places at once.
