My $6.75 per year vps was a Dedirock Black Friday sale that I found https://lowendtalk.com. https://cheapvpsbox.com/ reports several nice Los Angeles sales still going on from various providers. My London, Tokyo, and Amsterdam VPSs are holiday sales from RareCloud and Racknerd - all less than $19/year.
Before I saw this comment I was curious and used dig+ARIN to look up the IPs and saw they were at Cloudflare. Given how rapidly the data changes and that the updates are via Websockets, do you get benefits from them serving assets, or is that to obscure the origin so it doesn't get extra attention, skewing the results? Cool project!
