1) The document discusses the creation of a website called sinsai.info to aggregate earthquake information from various sources using open source tools like Ushahidi during the 2011 Tohoku earthquake and tsunami in Japan. 2) Performance issues arose as traffic increased, including high latency and database overload. Solutions involved optimizing the database, adding an Elastic Load Balancer, and backing up to Amazon S3 and EBS. 3) The website served as a useful resource for earthquake information, and the author thanks AWS for its services which helped handle the increased traffic and issues during the disaster.
