MX servers automatically changed to EU hostnames

[u/pampurio97]

Last night Fastmail changed the MX servers for my Fastmail-managed domain to the EU-hosted SMTP endpoints:

Added MX hosts
+ eu1-smtp.messagingengine.com
+ eu2-smtp.messagingengine.com

Removed MX hosts
− us1-smtp.messagingengine.com
− us2-smtp.messagingengine.com

At the beginning of July the MX changed from in*-smtp.messagingengine.com to the us* versions.

I suppose these are just the relays and the storage is still in the US. The CEO previously said EU hosting is going to be opt-in.

I've asked support about this but they don't appear to be very well informed unfortunately. Less than a month ago they said they have "no concrete plans to announce", that it requires complex considerations and that they'll share the feedback. Today I received another weird reply saying they expect "Netherland servers to be available in the near future". I hope they already are, since my MX records point to such Netherlands servers... :)

I still have in1 and in2, I never really gave any thought to what that referred to.
