When Universal Studios Hollywood rides break down
Closures by the hour they start
1,069 breakdowns · late starts excluded
Breakdowns cluster at 5pm, with 373 of the 1,052 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 759 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 17 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.
Universal Studios Hollywood downtime day by day
Share of ride hours lost
22 Aug to 20 Oct
The worst day in this window was 2 Sept, when 77.7% of the park's ride hours were lost and 36 of 36 rides went down at some point.
Uptime is the share of the park's own operating minutes a ride was running, recorded every few minutes and averaged over 60 days. A closure counts as one breakdown when it lasts ten minutes or more; shorter stops still count towards time lost, because a two-minute reset is not a fault. Touching closure windows are merged into one closure - a ride shut all day arrives from the feed as that day sliced into the sampling interval, and counting each slice would report one bad day as a hundred breakdowns.
