Breakdowns cluster at 8pm, with 389 of the 1,788 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 456 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 12 closures start in the 11pm 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 3 Oct, when 24.5% of the park's ride hours were lost and 35 of 36 rides went down at some point.
