Recently, my several "global overview" metrics keep stalling, and it's not my computer being slow... Most likely it's the indexer/Subgraph fetching new data on the chain, or RPC is being rate-limited. On-chain data isn't flowing smoothly the moment you turn on the faucet; first, someone has to scan logs and organize them into a queryable structure. If any part of that pipeline gets backed up, you'll see "It was fine just a moment ago, why is it suddenly blank/delayed?"

Especially when new L1/L2 incentives or TVL suddenly spike, request volume surges, and RPC can't handle it at first, the index can fall behind by hundreds of blocks. I understand the complaints from veteran users about "mining, selling," but what I care more about is: don’t get too excited when looking at the dashboard. First, check if the data timestamp is still stuck ten minutes ago... Anyway, I now wait for it to catch up before drawing conclusions; taking it slow is more reassuring.
