The Markle Foundation's website faced several challenges including security vulnerabilities, performance issues, outdated design, and a complicated document library. With updates to the backend and design, as well as migration to Drupal 7 and implementation of Apache SOLR, the website is now better equipped to meet their needs and further their mission.
