Exactly. Regional distribution can be vital. Our customer Kiwi.com had a datacenter fire. 10 of their 30 nodes were turned to a slag heap of ash and metal. But 20 of 30 nodes in their cluster were in completely different datacenters so they lost zero data and kept running non-stop. This is a rare story, but you do NOT want to be one of the thousands of others that only had one datacenter, and their backups were also stored there and burned up with their main servers. Oof!
