Breakdowns cluster at 8pm, with 270 of the 1,409 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 420 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 184 closures start in the 9pm 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 14 Aug, when 37.4% of the park's ride hours were lost and 34 of 42 rides went down at some point.
