Update: Test Track reopened at EPCOT at 11:55 a.m. EDT Sunday, Aug. 2. The ride had been unavailable since 8:35 a.m., shortly before the park's 9 a.m. general opening.
Test Track briefly went down again at 12:15 p.m. and returned 10 minutes later. CrowdLevels recorded an 85-minute posted wait at 3:10 p.m. EDT.
The Sunday closure followed a much longer interruption Saturday. Test Track went down at 10:15 a.m. and did not return until 7:40 p.m., leaving it unavailable for more than nine hours of the operating day.
Disney has not listed a cause for either weekend closure. CrowdLevels' current status and downtime feeds marked the interruptions as unplanned, and the site's freshness check was current when the reopening was reviewed.
The ride had recently restored its finale's sliding-door effect and began using all eight rows in its loading station. Those changes did not establish a reason for either weekend closure, and there is no indication that they are connected.
Guests heading across EPCOT should check the My Disney Experience app or the attraction entrance before making the walk. Test Track sits on the east side of World Discovery, and a long detour has very little horsepower.
