Reduce latency and increase cache hits with Regional Tiered Cache

What this post added

Introduced Regional Tiered Cache, a new tier within the existing Tiered Cache offering. This feature adds a middle-tier in each region that lower-tier data centers query first on a cache miss, before querying a distant upper-tier. This is particularly beneficial for customers using Smart Tiered Cache or custom topologies with upper-tiers in one or two regions, aiming to reduce latency for global traffic by improving cache hit rates and reducing origin egress.
