The best model for this scenario is the Poisson distribution as it is used to model the number of occurrences of events in a fixed interval of time or space when the events happen independently and randomly. In this case, the occurrence of nonworking web URLs is random and independent of other URLs, and we are interested in the number of occurrences within a minute. Binomial would not work as the probability of success (encountering a nonworking URL) is not constant for every website. Hypergeometric would not work as we are not sampling a fixed population with a known number of successes and failures. Geometric would not be the best choice as it models the number of trials needed to achieve the first success, whereas we are interested in the overall number of nonworking URLs encountered in a minute.
