  "account": "On October 9th, SURFnet Infinity celebrates the launch of the SNTPings event, which is the biggest edition to date. Pinging will commence on Friday and continue throughout the weekend until October 11th at 23:59. The event is hosted by Nikhef with uplinks provided by SURF. Participants send ping packets to a specific IPv6 address, creating a shared canvas for everyone to see. The livestream offers two views, one in 4K resolution and another in 1080p30. To help stress-test the new network, the event offers 1.6Tbps of bandwidth. Overwatch, a homegrown software, manages the event by monitoring pings, applying packet loss, and selecting suitable users for the livestream. Remaining traffic is then sent to Stoffig, which paints the packets onto the canvas for the world to see. Finally, Kassa2 converts the canvas to an HDMI link and streams it through a 100Gbit/s connection, making the event accessible to all participants.",
