Lately, I've been noticing that on-chain data keeps "hanging" for a moment. At first, I thought my internet connection was bad... But after checking around, I realized that it's often not the chain being slow, but the queue of processes in between: the indexer needs to process the new blocks first, the Subgraph is still syncing/rebuilding, and the front end is making RPC calls that get rate-limited. Layer after layer, it’s like your page refresh is hesitating.

Forget it, to put it simply: what you see is the "latest," but they might not have had time to organize the "latest" properly. Recently, the incentive programs on the testnet have made everyone more vigilant about data, plus the speculation about token issuance and whether the mainnet will release tokens, causing a surge in calls, making rate limiting even more obvious...
My current clumsy solution is to switch between several RPC endpoints, not to rely on a single subgraph as the ultimate truth, relax my mindset—anyway, it will catch up eventually.
