These days I found out about thousandeyes where I can have a general outlook on what major servers are out.
It seems like they also have a paid version but I am not sure of the quality that I would get.
So other than thousand eyes, where and how would be the best way to find out about the state of the internet. Datas that I am looking for are, e.g time when the server is down and which servers (because there are always backup servers for the big companies). It’ll be good if it can somehow be linked to the reason of why a said server is down, e.g due to a breach or just a planned maintenance.
P.S Bonus if there is an open source way to do this!
Thank you beforehand!
