**What it does not test.** Does not establish that health data hosting will move away from Microsoft, since the ruling upholds the existing arrangement rather than ordering any change.

**How this item counts.** No movement: no answer to who owns, who operates, whose law governs or who made the parts changes. Weight 0\. Court upholds existing Azure hosting of one study, nothing about it changes. [European Sovereignty Index](https://sovereigntymonitor.eu/sovereignty-index/)
