B.net Index: Server 2

You might ask: "With modern remasters (StarCraft Remastered, Diablo II Resurrected) and Discord, why bother with a 20-year-old index server?"

Here are the compelling reasons:

If you have legacy IS2 data that needs to be migrated today, follow this path: B.net Index Server 2
