%X We combine all the available experimental information on Bs mixing, including the very recent tagged analyses of Bs ¡ú J/¦·  by the CDF and D  collaborations. We find that the phase of the Bs mixing amplitude deviates more than 3¦Ò from the Standard Model prediction. While no single measurement has a 3¦Ò significance yet, all the constraints show a remarkable agreement with the combined result. This is a first evidence of physics beyond the Standard Model. This result disfavours New Physics models with Minimal Flavour Violation with the same significance. PACS Codes: 12.15.Ff, 12.15.Hh, 14.40.Nb
