Is Copilot for M365 Chat (Graph and Web-grounding) data processed in US?

Hey,

Web plugin in Copilot for M365 Graph-grounded Chat will be ON by default in near future. Copilot in other applications also uses web-grounding (and cannot be turned of without tenant level restriction).

Microsoft documentation states that Copilot (Commercial data protection) chat might process data in States.

Does the  statement also apply in Copilot for M365 Web-grounded chat and other applications? 

"To provide chat responses, Copilot uses global data centers for processing and may process data in the United States. Optional, Bing-backed connected experiences don't fall under Microsoft's EU Data Boundary (EUDB) commitment." (Copilot Privacy and Protections | Microsoft Learn).

Some companys dont want any of their data leaving EU data Boundary. Is this something we must be conserned?

Thanks for your reply in advance!
