Digital Ocean seems to be not good enough for FreeBSD hosting, at least for now.
Unfortunately their FreeBSD image for installation is far from ideal.
sshd_conf is impaired, also they do not allow complete networking: one can only login as user
Although extra security is always appreciated, one may need to tighten it according to his own standard.
Also, Digital Ocean is significantly slower than Linode, at same price range.
Overall it is not worth it.
