The paradigmatic view where information is seen as a more fundamental concept than the laws of physics leads to a different understanding of spacetime, where the causal order of events emerges from correlations between random variables representing physical quantities. In particular, such an information-theoretic approach does not enforce a global spacetime structure. By following this path, we conclude that perfect signaling correlations among three parties are possible which do not obey the restrictions imposed by global spacetime. We show this using a recent framework based on the sole assumptions that locally, quantum theory is valid and random variables can be described by probability distributions. Our result is of zero-error type and can be seen as an analog to a three-party appearance of quantum non-locality which manifests itself by satisfying a condition with certainty, whereas the same is impossible for any local theory.
