• More Azure interconnects

A region is a collection of multiple, fault de-correlated (tolerant), completly independent data centers called ADs (Availability Domains). Newer regions have been launched with a single AD, while classical regions (PHX, ASH, LON, FRA) have 3 ADs. For single AD regions you may need to use ADs in other regions for true DR and resiliency.

Inside each AD there are multiple (at least 3) Fault Domains (separate physical infrastructure inside a datacenter/AD).

All physical components in an AD are connected to a physical network that is non-oversubscribed, low latency, high speed between hosts in the same AD. On top of it, there is a Virtual network where network and storage IO is moved out of hypervisor which enables low overhead and bear-metal instances (Off-box Network Virtualization)
