Scope verdict

Ownership reviewed, controller unresolved

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

How we classify services

Leaseweb Object Storage is the object storage service of the Dutch cloud provider Leaseweb. It uses standard protocols and the S3 API to organise data into buckets and distributes it redundantly across geographically separated systems, which is aimed at large volumes that have to stay durable and available.

Leaseweb is headquartered in the Netherlands, which makes the service a European alternative to the American storage clouds. On-demand billing suits unpredictable growth, while the committed tier fits workloads whose volume is known in advance.

Pricing

Storage is billed per GB per month. On-demand usage carries no commitment, while the committed tier requires a minimum of 500 GB per month and is billed monthly. Incoming traffic is free.

Evidence: Current daily MX lookup ↗

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.

Incoming business email

Mail handled by: Microsoft 365 Non-European provider

Additional service signals

Published SPF, DKIM and discovery records can reveal configured links to major platforms beyond incoming mail.

Mail-client discovery

Microsoft 365

Non-European provider

CNAME autodiscover → autodiscover.outlook.com

The standard Outlook discovery name routes mail-client setup to Microsoft 365. This is stronger evidence of tenant configuration than an old verification token, but does not reveal mailbox storage location.

Mail-signing setup

Microsoft 365

Non-European provider

CNAME selector1._domainkey → selector1-leaseweb-com._domainkey.leasewebglobalbv.onmicrosoft.com · selector2._domainkey → selector2-leaseweb-com._domainkey.leasewebglobalbv.onmicrosoft.com

A provider-specific DKIM record is published for Microsoft 365. This shows configured mail-signing infrastructure, but not that every message currently uses it.

Sender authorisation

Microsoft 365

Non-European provider

SPF include:spf.protection.outlook.com

Microsoft 365 is authorised to send email for this domain. The SPF entry can be unused or stale and does not reveal the configured data region.

Current DNS record ↗Provider setup guide ↗

This is a targeted check, not a complete zone inventory. Generic Google and Microsoft verification tokens are ignored because they do not prove product use or a data flow. DNS normally cannot list arbitrary subdomains or customer-chosen DKIM selectors, including Salesforce selectors. Missing signals are not proof that a provider is unused.
