I worked in a top 15 Azure customer. This is not unusual at all, especially in the newer regions. Talk to your TAM before you make attempt major capacity changes in a region. They may have advice on specific SKUs to use or which zones have capacity (e.g. when austrailaeast was being built 80%+ of the capacity was in one zone for many months). If you aren't a big spender you may not have a TAM who can get this info for you. Welcome to Azure.
