I tried once, even though the on-chain blocks were coming out, my dashboard data just "stuck for a moment," and I thought the script had crashed. Later, after checking the logs, I found that several layers were holding things back: the Subgraph indexer was still catching up, RPC was rate-limited (like a 429 error), and I had opened too many concurrent requests myself, resulting in it being like a robotic arm being suddenly slammed on the brakes... To put it simply, it's not that the chain has no data, but that the path you're using to fetch data is blocked.

Recently, before and after the main public chain upgrades/maintenance, everyone has been guessing whether projects will migrate. I'm actually more concerned about "not losing sight during those few hours of upgrade monitoring." Now I just play it safe: implement exponential backoff retries for requests, compare key metrics from multiple sources, and also leave some margin for on-chain execution costs. Anyway, data hiccups are quite normal, just don't get carried away with emotions and place reckless orders.
