Scenario
Round-trip latencies for chained requests getSlot and getBlock(slot) with start-to-start throttling of (at least) 1100 ms for every request.
Also, slot number consistency with block availability and block age. The block propagation comparison is conservative and latency-agnostic.
Of the possible 31 regions, 22 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, and Singapore.
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: 42 of 44 datasets were available from 22 selected regions x 2 endpoints.
2 datasets were not available at the time of the report generation: A.aws-me-central-1, B.aws-me-central-1.

Findings
| Endpoint | Lagging | Unique | Lowest | Arrival Tms | Arrival Region | Highest | Arrival Tms | Arrival Region |
|---|---|---|---|---|---|---|---|---|
| A. silent-magical-tree.solana-mainnet.Quiknode.pro | 9 | 22 | 419,171,463 | 1,778,555,421,395 | Singapore / AWS | 419,171,534 | 1,778,555,450,035 | Frankfurt / AWS |
| B. tritono-solanam-e780.mainnet.Rpcpool.com | 0 | 21 | 419,171,463 | 1,778,555,421,395 | London / AWS | 419,171,534 | 1,778,555,450,030 | Singapore / AWS |
We detected 9 responses whose sendTms, arrivalTms and number were such that we can state the endpoint was lagging in the respective region.
E.g. on arrivalTms=1,778,555,441,219 in Frankfurt / AWS, we received number 419,171,512 from B. tritono-solanam-e780.mainnet.Rpcpool.com. Afterwards, on sendTms=1,778,555,441,222 we dispatched a request to A. silent-magical-tree.solana-mainnet.Quiknode.pro, which returned lower number 419,171,511 at arrivalTms=1,778,555,441,224. Therefore, A. silent-magical-tree.solana-mainnet.Quiknode.pro was lagging because it was returning lower number 419,171,511 well after B. tritono-solanam-e780.mainnet.Rpcpool.com advanced to 419,171,512.
Summary
Global and continental aggregations by endpoint and method(s) depend on completeness of data in the details.
