This service remains visible for context, but it is not counted or recommended as a European-controlled option.

How we classify services

Operational dependency warning

Relies heavily on non-European providers

Current public evidence shows 4 non-European infrastructure or email dependencies across 3 providers: Amazon SES, Amazon Web Services, Microsoft. The reviewed operational path is therefore not entirely European.

Review dependencies ↓

Sailfish OS is an open source operating system for smartphones, built on Linux and developed by the Finnish company Jolla. It includes a proprietary layer that runs Android applications, so common apps still work. It ships on Jolla's own devices and reaches other hardware through community ports.

A Finnish vendor makes Sailfish OS a European alternative to the American mobile platforms, and the Linux base gives more control over what runs on the device. It suits people who want a phone that is not tied to the usual app store ecosystems and who accept some tinkering.

Data and operations

Infrastructure and email path

Verified operational dependencies, shown separately from ownership and from the service's core data hosting.

Public website

Amazon Web Services

US-controlled cloud
Observed
A 34.254.143.49, 54.228.152.43, 52.17.146.184 · AS16509

Why this matters

This public website route ends on Amazon Web Services, whose European seller is wholly owned by Amazon.com, Inc. An EU region can provide European data residency but remains under US ultimate ownership. DNS does not reveal the AWS region, the core service's host, or use of the separately operated AWS European Sovereign Cloud.

Incoming business email

Microsoft 365

Non-European provider
Observed
MX 0 sailfishos-org.mail.protection.outlook.com

Why this matters

Published MX records route incoming business email through Microsoft 365. Correspondent details and message content can therefore enter this non-European provider's systems; MX does not reveal the configured storage region.

Authorised outbound email

Microsoft 365

Non-European provider
Observed
SPF spf.protection.outlook.com

Why this matters

This domain authorises Microsoft 365 to send email. If active, recipient details and message content can be processed by this non-European provider. SPF does not reveal its configured storage region.

Authorised outbound email

Amazon SES

US-controlled cloud
Observed
SPF amazonses.com

Why this matters

This domain authorises Amazon SES, infrastructure under US ultimate ownership, to send email. If active, recipient details and message content can be processed there. SPF does not prove active use, the selected AWS region, or use of the separately operated AWS European Sovereign Cloud.

Public DNS records identify visible providers and routes, not every backend location or private data-region setting.
