We have successfully restored all Base Sepolia features. Virtual Testnets and WebSockets are back up and fully operational. The one remaining item is `eth_subscribe`, which is currently unavailable for both Node and Virtual TestNets. Our team is aware and actively working on it - we expect it to be re-enabled by the morning hours.
