We report a stability below 7 × 10 '17 of two independent optical lattice clocks operating with bosonic 88 Sr isotope. The value (429 228 066 418 008.3(1.9) syst (0.9) stat Hz) of the absolute frequency of the 1 S 0-3 P 0 transition was measured with an optical frequency comb referenced to the local representation of the UTC by the 330 km-long stabilized fibre optical link. The result was verified by series of measurements on two independent optical lattice clocks and agrees with recommendation of Bureau International des Poids et Mesures.
