- investigating Mar 24, 2026, 09:16 AM UTC
We are investigating intermittent 503 errors affecting the Avalanche Fuji Testnet. Some customers may experience temporary request failures or degraded performance. Our team is actively working to mitigate the issue and restore full service stability. We will provide an update as more information becomes available.
- identified Mar 24, 2026, 09:53 AM UTC
We have identified this as an upstream network-wide issue affecting Avalanche Fuji Testnet infrastructure. The C-chain (EVM) is currently affected and blocks have stopped being produced. This is a network-wide issue and is not isolated to Quicknode. The Avalanche team has been notified and is investigating. All Avalanche Fuji Testnet RPC endpoints are currently affected. Customers may experience 503 errors, request failures, or timeouts until the network stabilizes. We will provide the next update by 11am or sooner as information becomes available.
- monitoring Mar 24, 2026, 02:55 PM UTC
The upstream network issue has stabilized and blocks are now being produced. Our team is actively monitoring to ensure full service restoration. Customers should see improved performance, though some intermittent issues may still occur until all nodes are fully synchronized.
