Washingtonian obtained outage information via DC Metro Metrics, an open-source project that takes real-time data released by Metro and compiles it over time. Outages are periods when escalators are down for repairs, inspections, or renovations or when they’ve been turned off to control foot traffic but aren’t necessarily broken. Our chart covers October 1, 2014, to September 30, 2015.
