Just now, I checked the on-chain data and it "lagged" again, and a bunch of people in the group thought the project team was hiding something... Actually, many times it's just that the indexer/Subgraph can't keep up, or RPC is being rate-limited. When your frontend requests data, it has to fetch logs and assemble the state, and if the nodes are busy plus many requests, it causes queuing. Slow responses feel like a network disconnection; plus, some subgraphs are rebuilt or rolled back, so data for certain minutes might be missing, which looks especially alarming. To put it simply, it's not that the chain has "stopped," but that the data pipeline layer you're viewing is congested. Recently, with the expectations of rate cuts and discussions around the dollar index, the market has been swinging wildly, and everyone is paying closer attention, which puts more pressure on RPCs... Anyway, before I see a waterfall, I cross-check two or three data sources first, or it's easy to get misled by a "lag."
