@nprofile1q... It's theoretically an issue but not one we expect to be a problem for us in practice especially on a provider like Xenyth. The same theoretical issue would exist buying used server hardware too. None of that hardware has good security in practice even if it's brand new. The CPUs might have reasonable security but the motherboards from ASRock, Supermicro, etc. definitely lack it. We plan to do colocation in the future but we're not ready to deal with that yet.
