For the cost of 10+ VPS hosts around the globe, my "user experience
monitor" uses a home-grown script to query certain records having a
different data value depending on which anycast site/server I hit,
saving statistics to be collected and analyzed. Low TTLs (less than my
polling frequency) allow me to compare directed queries to natural,
capturing the impacts of network anomalies, intermediary recursive
resolver performance, etc.
Simple, but fairly elegant, and very useful.
Rebuilt that wheel, I suppose, but no expensive 3rd party product. And
just the info/context that I care about. Happy to share more info, if
