From the page: Still not sure what BitScope is? BitScope is a built and tested (and previously build it yourself DIY), open design, digital storage oscilloscope and logic analyzer (also, digital sampling oscilloscope, mixed signal oscilloscope).
A collection of tools (DNS lookup, ping, traceroute) which can be used from a web browser.
On 2021-03-23, I could not find the tools. Note that this site is related to SolarWinds, who were attacked recently.
