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, 2 were selected for data collection: Oregon 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: 4 of 4 datasets were available from 2 selected regions x 2 endpoints.
Findings
| Endpoint | Lagging | Unique | Lowest | Arrival Tms | Arrival Region | Highest | Arrival Tms | Arrival Region |
|---|---|---|---|---|---|---|---|---|
| A. mainnet.helius-rpc.com | 0 | 15 | 415,678,155 | 1,777,164,850,520 | Oregon / AWS | 415,678,232 | 1,777,164,881,353 | Oregon / AWS |
| B. beta.helius-rpc.com | 0 | 16 | 415,678,155 | 1,777,164,850,522 | Oregon / AWS | 415,678,232 | 1,777,164,881,359 | Oregon / AWS |
No conclusive proof of block lag was found in this dataset / interval.
