I went with Fastmail just because it's not hosted in the US (they're in Australia)
All the comfort of the hemisphere least likely to suffer nuclear fallout coupled with the familiar warm embracing hug of the five eyes security panopticon.
Fastmail is an Australian company, but their servers are located in the US [0]

They are hosted in the US, legal entity is in Australia, so nothing was gained.
Unfortunately, I remember reading that Australia now has weak privacy laws:
> The Telecommunications Assistance and Access Bill (TAAB or AssAccess) require technology companies like FastMail, Google, Apple, Cisco to provide Australian law enforcement and security agencies with access to all communications without any judicial oversight, transparency, or reason. The only restrictions offered to protect people’s privacy is the vague terms “reasonable and proportionate.”
