Second Life

Second Life arrived in 2003 with an ambition that most virtual worlds did not share: rather than providing a game with objectives, it would provide a platform where users created the world and its economy themselves. Linden Lab's decision to allow residents to own intellectual property rights to their in-world creations was a foundational policy choice that enabled an economy denominated in Linden Dollars — a currency that could be converted to real US dollars through the LindeX exchange. At its cultural peak in the mid-2000s, Second Life attracted news coverage, corporate virtual offices, and academic interest in virtual economies that presaged later discussions about NFTs and virtual ownership.

The platform's technical architecture is unusual. Second Life runs on a distributed grid of simulator servers — "sims" — each hosting a 256-meter-square region of virtual land. Residents cross between regions by crossing sim boundaries, a transition that requires server handoffs and is notoriously prone to failures called "crossing lag." The Linden Dollar economy, the inventory system that stores a resident's virtual possessions, the Marketplace for buying and selling goods, and the login and authentication infrastructure are all separate backend systems that can fail independently. The viewer — the client software — also has an active third-party development community producing alternatives to the official Linden Lab viewer.

Second Life outages produce a range of experiences depending on which system fails. Login server problems prevent residents from entering the grid entirely. Sim crashes eject residents from the affected region, sometimes causing inventory loss or avatar rollbacks. Asset server failures cause textures to stop loading, producing the gray, unrendered appearance — familiar to long-time residents — of a world where nothing has loaded. The LindeX currency exchange may halt processing during backend problems, freezing transactions for residents who trade Linden Dollars commercially. Marketplace purchases may fail to deliver purchased items to inventory even after payment processes.

Outage.gg tracks Second Life grid status using community-submitted reports from residents. If login is failing, sims are crashing, or the grid is degraded, the live status page reflects current reports from the Second Life community.
