I just checked an address on the blockchain, and the interface suddenly "lagged," I thought my internet crashed... Later I realized it was probably someone limiting traffic on the indexer/Subgraph/RPC chain: you're not directly reading the chain when you click, you're asking someone else's organized data first; when there are many people, or nodes can't handle it, or the indexer hasn't caught up with the latest blocks, you'll get that feeling of "no error but a half-second delay." To put it simply, data also needs to queue.

What scared me a bit was that I almost casually clicked on a "repair connection" link from an unknown source (there have been a lot of phishing lately), but luckily I saw a discussion in the group about hardware wallet shortages, and suddenly became alert: the more lag there is, the easier it is to make people anxious, and when you're anxious, you're more likely to fall for it. Anyway, whenever I encounter lag now, I first switch RPC or wait for a few seconds, don't click randomly, don't sign randomly, just do that for now.
