Base’s public RPC change window runs Oct 8 12:00 UTC to Oct 9 12:00 UTC; at 12:05 UTC implementation was unconfirmed. QuickNode Hedera, OP-stack and Sui Mainnet maintenance is scheduled for Oct 8; Solana Agave v4.3.0 is in progress through Oct 11, while RPC, WebSocket and gRPC stay available.

Gaps

Alchemy’s pricing page and docs still disagree on Free throughput (500 versus 300 CU/s). Gelato and Pangea pages failed to load; Maestro pricing remains inaccessible. Reservoir’s NFT API status conflicts with Relay redirects; Shovel hosted-query and ShroomDK terms remain unverified, and Solana Explorer MCP setup was unreadable. QuickNode’s Tempo notice body says Oct 8 while the status page marks the Oct 7 window complete. World Chain’s intermittent 503 incident remains active.
