Start by separating the chain from the front end. Hyperliquid's layer-1 has kept producing blocks through every widely reported incident; what fails is the layer people touch. On July 29, 2025, the API went down for about 27 minutes, from 14:20 to 14:47 UTC, under what the team called a spike in traffic, and for that window nobody could open, close or withdraw through the app even though the chain was fine. The team refunded affected traders automatically. Smaller versions of the same thing, the app hanging or orders not confirming while the explorer shows blocks, are the most common "Hyperliquid is down" report.
The second cause is the deposit side. A USDC deposit that does not show up is usually an Arbitrum RPC delay, a bridge confirmation still pending, or an amount under the 5 USDC minimum, and the docs have a troubleshooting page for each. A deposit sent on the wrong network is not an outage and is not recoverable. If you are in the United States and the site simply refuses to load or connect, that is the geoblock working as intended, not downtime.
If the front end is up and your problem is that a balance or wallet has been flagged, that is a compliance event, not an outage, and there is no status page that will resolve it. Hyperliquid posts incident updates on X and in its Discord, which is where to look before assuming the worst.
