I want to know the answer to the following question:
What was the name of the non-subscription Xbox online gaming service?
All the background I'm provided with is that "When the Xbox 360 was released, Microsoft's online gaming service Xbox Live was shut down for 24 hours and underwent a major upgrade, adding a basic non-subscription service called Xbox Live Silver (later renamed Xbox Live Free) to its already established premium subscription-based service (which was renamed Gold).". Is that enough to answer the question?
Answer: yes
