Perplexity built its own key-value store because DynamoDB's read path and bill stopped fitting 50 KB search items. Here is the checklist for when leaving is justified.
AWS says it cannot restore data held only in Bahrain (me-south-1) or in one UAE zone. Multi-AZ gave availability, not recovery, and only cross-region copies survived.
