Valley Fair downtime day by day
Share of ride hours lost
12 Sept to 1 Nov
The worst day in this window was 20 Sept, when 17.4% of the park's ride hours were lost and 9 of 39 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 18 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.
