Scenario
Block propagation and regional arrival lag.
The probe(s) subscribe with Yellowstone/Geyser Subscribe blocks over gRPC and capture each block arrival. Datasets from all regions are merged by number + hash to detect the leader and followers for each block.
Of the possible 31 regions, 31 were selected for data collection: Oregon, N. California, Mexico, Columbus, OH, N. Virginia, Montreal, São Paulo, Ireland, Zaragoza, London, Paris, Frankfurt, Zurich, Milan, Stockholm, Cape Town, Tel Aviv, Dubai, Mumbai, Hyderabad, Bangkok, Kuala Lumpur, Singapore, Jakarta, Hong Kong, Taipei, Seoul, Osaka, Tokyo, Melbourne, and Sydney.
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: 31 of 31 datasets were available from 31 selected regions x 1 endpoint.
