Archival indexing delay, mainnet epoch 1017 (slot 439344001+)
Resolved after 15 minutes, affecting RPC, on August 15, 2026.
We experienced a delay in archival block indexing for a range of mainnet slots at slot 439344001 (epoch 1017). Backfill is in progress and most slots have already been restored; a small number remain and are being reindexed. Live streaming and recent blocks were unaffected.
