Given a fixed graphH, what is the (exponentially small) probability that the numberXHof copies ofHin the binomial random graphGn,pis at least twice its mean? Studied intensively since the mid 1990s, this so‐called infamous upper tail problem remains a challenging testbed for concentration inequalities. In 2011 DeMarco and Kahn formulated an intriguing conjecture about the exponential rate of decay of for fixedε> 0. We show that this upper tail conjecture is false, by exhibiting an infinite family of graphs violating the conjectured bound.
