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, 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: 62 of 62 datasets were available from 31 selected regions x 2 endpoints.

Findings
| Endpoint | Lagging | Unique | Lowest | Arrival Tms | Arrival Region | Highest | Arrival Tms | Arrival Region |
|---|---|---|---|---|---|---|---|---|
| A. rpc.lava.mainnet.Dteam.tech | 19 | 3 | 5,127,689 | 1,779,563,285,298 | N. California / AWS | 5,127,691 | 1,779,563,311,659 | Columbus, OH / AWS |
| B. lava.tendermintrpc.Lava.build | 103 | 3 | 5,127,689 | 1,779,563,285,461 | Zurich / AWS | 5,127,691 | 1,779,563,311,799 | N. Virginia / AWS |
We detected 122 responses whose sendTms, arrivalTms and number were such that we can state the endpoint was lagging in the respective region.
E.g. on arrivalTms=1,779,563,297,841 in Cape Town / AWS, we received number 5,127,690 from B. lava.tendermintrpc.Lava.build. Afterwards, on sendTms=1,779,563,298,480 we dispatched a request to A. rpc.lava.mainnet.Dteam.tech, which returned lower number 5,127,689 at arrivalTms=1,779,563,299,465. Therefore, A. rpc.lava.mainnet.Dteam.tech was lagging because it was returning lower number 5,127,689 well after B. lava.tendermintrpc.Lava.build advanced to 5,127,690.
E.g. on arrivalTms=1,779,563,302,452 in Bangkok / AWS, we received number 5,127,690 from A. rpc.lava.mainnet.Dteam.tech. Afterwards, on sendTms=1,779,563,304,588 we dispatched a request to B. lava.tendermintrpc.Lava.build, which returned lower number 5,127,689 at arrivalTms=1,779,563,305,742. Therefore, B. lava.tendermintrpc.Lava.build was lagging because it was returning lower number 5,127,689 well after A. rpc.lava.mainnet.Dteam.tech advanced to 5,127,690.
Summary
Global and continental aggregations by endpoint and method(s) depend on completeness of data in the details.
