      * Previously, the Machine API controller read the zone number to populate machine zone information. For machines in {azure-short} regions that only support availability sets, the set number is used to represent the zone, so the Machine API controller did not populate their zone information. With this release, the Machine API controller references the {azure-short} fault domain property, which works for both availability sets and availability zones, to correctly read the fault domain in each case so that machines always report a zone.
