On-chain data sometimes suddenly "hiccup," and it's not necessarily because your internet is slow.

Many pages rely on indexers/Subgraphs to organize on-chain logs into queryable tables, but it's not real-time magic: slow node synchronization, re-running indexes, or even a rollback of a block can cause the frontend to freeze temporarily.
Plus, with RPC rate limiting, when everyone queries at the same time (especially for things like unlock calendars or repeated staking unlocks), requests pile up or get cut off directly, resulting in the numbers you see fluctuating—sometimes showing, sometimes not.

What I fear most isn't slowness but chaos—slow is just a matter of waiting, but chaos means the same data doesn't match across different places, which can mess with your mindset.
Anyway, when I encounter this, I just wait a few minutes, switch to a different RPC, and don't rush to conclusions... for now, that's how I handle it.
