Breakdowns cluster at 3pm, with 199 of the 1,199 closures that started before the park's final hour beginning then - so the ride you most want is safest earlier in the day, not saved for last. A further 275 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 24 closures start in the 6pm hour, when the park is shutting - those are rides finishing their day, not failing, so they are left out here.

The worst day in this window was 10 Aug, when 96.4% of the park's ride hours were lost and 31 of 31 rides went down at some point.
