Scenario
Round-trip latencies for chained requests /status and /block?height= with start-to-start throttling of (at least) 1100 ms for every request.
Also, latest block-height consistency with block availability and block age. The block propagation comparison is conservative and latency-agnostic.
Of the possible 31 regions, 2 were selected for data collection: Columbus, OH and Frankfurt.
Each location probe breaks its processing loop if / when the endpoint response is too-many-requests, a.k.a. HTTP code 429 etc. Also, codes 401 and 403.
At the time of the report generation: 4 of 4 datasets were available from 2 selected regions x 2 endpoints.
