Have you also experienced this before, where on-chain data suddenly "freezes" for a moment and doesn't move for a while?

I usually don't blame my network first; many times it's because the indexer/Subgraph hasn't caught up with the blocks yet, or RPC is being rate-limited: what you're seeing isn't "the chain has stopped," but more like the backend is queuing to catch up. Especially when the market heats up and everyone checks balances or transaction history at the same time, node requests get overwhelmed, leading to packet loss or throttling, and the frontend just shows loading spinners. Recently, with the discussions about rate cut expectations, the US dollar index, and risk assets moving together, the on-chain activity also gets squeezed, making data delays even more noticeable... Anyway, now I get used to waiting a bit longer when looking at on-chain trends, checking multiple sources so I don't get thrown off by a sudden lag and lose my composure.
