The Solana Testnet is switching to Alpenglow, Solana's new consensus protocol (SIMD-0326). The Solana developers at Anza will turn it on at the start of Testnet epoch 1042, expected Thursday, September 24, around 17:30 UTC. The switch-over takes about 5,000 slots, which is roughly 15 to 20 minutes at Testnet's current speed.
What this means for you - Solana Mainnet is not affected. This change applies to Solana Testnet only. - The Testnet may be briefly unstable while the switch-over happens, for example with slower confirmations or short interruptions. This comes from the network itself. - Your Quicknode Testnet endpoints stay the same. You don’t need to change anything.
What we’re doing - Our Solana Testnet infrastructure is already running the required Agave v4.3.0. - We’re pausing all planned maintenance on Solana Testnet around the upgrade window. - Our team will be actively monitoring the network during and after the switch-over, and we’ll post updates here if we see any impact.
Try Alpenglow early:

We’ll update this notice once the upgrade is complete.
