World Backup Day is a day for people to learn about the increasing role of data in our lives and the importance of regular backups.
This independent initiative to raise awareness about backups and data preservation started out — like most good things on the internet – on reddit by a couple of concerned users. Let’s make this happen!

This tool provides information about traffic to our services around the world. Each graph shows historic traffic patterns for a given geographical region and service. You may select a region and then choose a service to view each respective graph. Graphs are updated as data is collected, normalised and scaled. By showing outages, this tool visualises disruptions in the free flow of information, whether it’s a government blocking information or a cable being cut.

Our goal is to reveal temporal variations in videos that are difficult or impossible to see with the naked eye and display them in an indicative manner. Our method, which we call Eulerian Video Magnification, takes a standard video sequence as input, and applies spatial decomposition, followed by temporal filtering to the frames. The resulting signal is then amplified to reveal hidden information. Using our method, we are able to visualize the flow of blood as it fills the face and also to amplify and reveal small motions. Our technique can run in real time to show phenomena occurring at temporal frequencies selected by the user.
