Ask HN: We just had an actual UUID v4 collision...

A rare UUID v4 collision occurred in a database, where two unique IDs generated using the 'uuid' package were identical. This is statistically unlikely, but not impossible. The developers are seeking to understand how this happened, despite not modifying the UUIDs. They are using the 'uuid' package and only generating IDs with the 'uuidv4' function. Investigation is ongoing.
