Level 3 is actually the name of a data center. The term that is used seems to be Tier 3. There are 4 tiers in data centers. Tier 1 is the least stable and the cheapest. Tier 4 is the most stable and most expensive. Tier 2 and 3 are in between. This pdf explains the differences between them. According to the pdf, Tier 3 data centers are “composed of multiple active power and cooling distribution paths, but only one path active, has redundant components, and is concurrently maintainable, providing 99.982% availability.” The pdf goes into more detail and compares all four tiers.
