The question of the server location is also very important to me.
According to IP 51.75.90.184 the server location is in Kassel, Germany.
The requirements of the regulation (EU) 2016/679 General Data Protection Regulation GDPR [EU Data Protection Basic Regulation (EU-DSGVO)] should be complied with.
Why the important aspects of /e/ cloud services are not clearly communicated remains an open question for me. If /e/ is fully committed to data protection, then transparency is an important askept.
P.S. In my opinion, Self-hosting /e/ Cloud Services is not suitable for laymen or “Mom and Dad”.
