Consider LeaseWeb? Their dedicated servers are expensive in the USA, but virtual servers aren't (and are also on their "Premium" provider network, rather than "Volume"):

Machines are older once cycled out from hosting so you might get e.g. Nehalem-C, but you get all the CPU features, e.g. aes and up to sse4.2.
Of course it depends on if what you want to put there fits into 40/60GB. Bear in mind that traffic is also the sum of in+out, unlike Hetzner - and overages are pricy, because it is that "Premium" transit.
(If you get an extra bill, check that it's valid as they have had issues with double-counting days. Compare Virtual Server/All Datagraphs in the customer portal with the VPS's own Network tab on the Manage page - if it doesn't match, something's up!)
Other options I have used: Vultr, UpCloud. I don't recommend SSDNodes, they aggressively overcommit on RAM and trim cache memory to ~1/8th of the promised size. OVH has also been spotty at times (and it's in Quebec which maybe isn't what you want).
Happy to announce that Riseup has offered to host our NextCloud evaluation.
This includes the OnlyOffice service.
The evaluation period runs from April 1 to September 30 2019.
Moving this ticket, its parents and its siblings to the Services Admin Team component where they belong.
