I know some here use Hetzner StorageBox.
I have been doing for several months without issue.
Now I am getting intermittent 'no route to host' and failed connections via SFTP app and SFTP in Terminal (Mac).
Not knowingly changed anything on my side and it does occasionally work.
Hetzner kindly changed the location of my storage box but it hasn't resolved anything.
Obviously for me to resolve but just wondered if anyone else seeing any issues.
