Fastmail offers EU data region
↗
Fastmail now lets users choose to store their primary email data in EU-based servers in Amsterdam, with fallback to US locations for availability.
Engineers who need to meet data-residency requirements can select a region that places the live copy of mail in Europe, affecting latency and compliance considerations. The change does not require modifications to email client settings unless explicit regional hostnames are desired. However, certain data such as logs, backups, and third-party service connections remain in the US, limiting the scope of EU-only storage guarantees.

Primary data copy can be placed in Amsterdam for EU-selected accounts, with US fallback for availability.
Metadata, system logs, emergency backups, and third-party service links stay in the US regardless of the chosen region.
Existing IMAP/POP3 hostnames continue to work via internal proxying, while optional regional hostnames give explicit control over where connections terminate.
THE READ
What the cluster adds up to.
Fastmail introduced a selectable EU data region, moving the primary copy of a user’s mail and files to its own servers in Amsterdam when the EU option is chosen. Previously all accounts were stored exclusively in US facilities in Philadelphia and St Louis. The new option preserves the same hardware and software standards used in the US sites.
Adopting the EU region does not force changes to email client configuration; the generic hostnames proxy internally to the active server. Engineers who want explicit routing can use the newly offered regional hostnames for IMAP, POP3, or web services. No additional software or licensing is required beyond toggling the account setting.
The offering does not guarantee that all data remains inside the EU. Metadata such as email addresses, user/customer information, storage for the Files feature, and linked third-party service details are replicated to all sites. System logs and emergency backups continue to reside in the US, so strict EU-only residency cannot be achieved with this service alone.
Availability is maintained through automatic fallback: if the Amsterdam servers become unreachable, connections route to one of the US locations, allowing continued mail access. This means that during an EU outage, read operations may be served from the US, introducing cross-atlantic latency while the primary copy is temporarily unavailable.
Replication strategy remains consistent: at least two copies of data are kept locally and a geographically separate copy is maintained elsewhere. For EU accounts, the geographically separate copy is presently stored in a US location, ensuring resilience while keeping the live copy in Europe when the region is selected.
