This paper gives a nearly logarithmic lower bound on the randomized competitive ratio for the Metrical Task Systems model [9]. This implies a similar lower bound for the extensively studied Kserver problem. Our proof is based on proving a Ramseytype theorem for metric spaces. In particular we prove that in every metric space there exists a large subspace which is approximately a "hierarchically wellseparated tree" (HST) [3]. This theorem may be of independent interest.
