Ronin Network Unavailable – Scheduled L2 Migration
Started: May 12, 3:34 PM
monitoring
We are aware that Ronin (chain ID: 2020) is currently unavailable. This is due to a planned L1 → L2 migration being performed by the Ronin team.
Starting at approximately 15:00 UTC on May 12, 2026 (block #55577490), the Ronin chain halted block production to begin its upgrade to an Ethereum L2. The migration is expected to take up to ~10 hours.
Once the Ronin team completes the migration and provides updated snapshots and configurations, we will bring up new nodes to restore full RPC supp...

Simulator issue
Started: Apr 28, 9:48 AM
monitoring
A fix has been implemented and we are monitoring the results. Alerts and Web 3 Actions delivery will also be delayed starting 10:13 UTC, current lag is ~16min we expect full recovery within 10-15min.

identified
We are continuing to work on a fix for this issue.
Apr 28, 9:48 AM
identified
We're investigating an issue where requests to the Simulator API with save: true, and dashboard flows that save a simulation, are currently returning errors for all networks. Ephemeral simulation runs (without save), and Node RPC simulation methods are not affected. We'll share an update as soon as we have more information.

Base Sepolia outage (affecting Node RPC, Virtual Testnets, Monitoring, Simulations)
Started: Apr 20, 7:05 PM
monitoring
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.
Apr 20, 9:01 PM
identified
We have resolved the issue affecting Node RPC, Monitoring, and Simulations on Base Sepolia - these features are now fully operational.
Our engineering team is continuing to work on restoring Websockets and Virtual TestNets. We will share another update as soon as those are resolved.
Thank you for your patience.
Apr 20, 8:30 PM
identified
We are currently experiencing an issue affecting all Tenderly features on Base Sepolia. Our team has been notified and is actively investigating and working on a fix.
All other networks are unaffected.
We will provide updates as the situation develops. We apologize for the inconvenience.

Started: Apr 2, 6:58 PM
monitoring
We are pleased to report that Node RPC, Virtual Testnets, Simulations, and Debugger have been restored and are operating normally.
Our team is actively working to resolve the remaining issues affecting the following components:
- Explorer
- Monitoring (Alerts and Web3 Actions)
We will provide a further update once these components have been fully restored. We apologize for the continued inconvenience.
