Bay Area Rapid Transit
With so many moving parts, BART.gov has to display correct real-time information to riders, as well as provide uninterrupted service in case of emergencies and heavy traffic. This website was a pixel perfect migration into Drupal. We had to deploy a solution that complies with all applicable accessibility guidelines including ADA Best Practices for Website Accessibility. In the end, we created a robust caching system to handle the real-time data throughout parts of the site.
During first week after launching, a major BART system failure caused 13 million hits to the site in a single morning with no noticeable performance impact.
