Recently, I keep encountering those "data freezes": the page clearly still lives, but the balance/positions seem to be stuck on the previous frame. To put it simply, it's not that the chain has stopped; it's that the indexer or subgraph is tracking blocks, and when reorganization or rollback occurs, it has to recalculate; combined with RPC rate limiting, during peak times, it directly returns a 429, causing the frontend to only display old cached data, making it look like "I clicked but nothing responded." Especially with new L1/L2s launching incentives to boost TVL, traffic surges, and old users are both complaining about mining and selling, while flooding the queries... Now I prefer to cross-check two or three sources on-chain, and casually glance at Gas, so at least I know I'm waiting for data, not trembling hands.
