Scheduled Maintenance

Upgrade 15: Isthmus Hard Fork May 9, 2025 16:00-17:00 UTC

The Isthmus upgrade will occur on Base Mainnet on Friday, May 9th @ 16:00:00 UTC (unix timestamp 1746806401). All Base node operators must update to v0.12.3 before this activation timestamp or they will halt when the network activates Isthmus. If you're not operating a Base node on mainnet, no action is needed. Base will continue to operate as usual without issue during the upgrade.

v0.12.3:
https://github.com/base/node/releases/tag/v0.12.3

For more information about the Isthmus upgrade for the OP stack (including Base) see:

Base Sepolia (Testnet) | External Chain Sync Issue
Resolved - This incident has been resolved.
May 1, 21:08 UTC
Identified - We've identified an issue causing some external Base Sepolia (Testnet) nodes to periodically fall out of sync with the tip of the chain. This issue is isolated to our test network — Base mainnet is unaffected, and all funds remain safe.

We're actively investigating the root cause and will provide updates as we learn more. If you're operating a Sepolia testnet node, no action is needed at this time. We'll keep you informed as we make progress toward a resolution.
May 1, 18:09 UTC
Base Sepolia (Testnet) | Flashblocks Temporarily Disabled
Resolved - flashblocks are re-enabled
May 1, 18:43 UTC
Identified - The issue has been identified and a fix is being implemented.

Planned Gas Target Increase to 32.5 Mgas/s
Completed - The scheduled maintenance has been completed.
Apr 30, 19:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Apr 30, 17:00 UTC
Scheduled - Base is increasing the per block gas target from 30 Mgas/s to 32.5 Mgas/s as part of continued, planned scaling efforts to bring a billion people onchain.

For builders and almost all Base users, no changes are necessary. But if you're running a Base node and notice any latency after the increase:

1. Monitor CPU and Disk I/O usage
2. Enhance disk throughput and use disks with lower read/write latency (NVMe SSDs recommended)
3. Improve CPU, focusing on single-core speed

You can also stop by the #node-operators channel in the Base Discord (https://base.org/discord) if you have any questions and we'll be happy to help you there!

Accompanying Readiness Report

Status: Ready ✅
Target increase: 2.5 Mgas/s (New total: 32.5 Mgas/s)

✅ Rollback ready

An upgrade and rollback script is included in each gas target increase in the event an unexpected issue is observed so that it can be reverted quickly if necessary.

✅ State growth

Node state growth is monitored each week to ensure long-term sustainability for node operators.

* Reth archive: 4.34TB
* Geth full: 9.4TB

✅ Execution speed, block building and block latency

Execution speed has been within established guardrails indicated above over the past week.

* Sequencer has 100% uptime, building blocks, since last increase
* >90% of blocks are built in two seconds or less

✅ All systems operational

All systems are operating within expected parameters to support this increase.

Scheduled - Upgrade 14 is scheduled to go live on Friday, April 25 on Base Mainnet.
https://docs.optimism.io/notices/upgrade-14

Reminder of action required for node operators:
Ensure your node is running Base Node v0.11.8 (released March 17) or higher to remain compatible with the upgrade. This is required to properly handle new events emitted from the SystemConfig contract.

Latest release: v0.12.2
https://github.com/base/node/releases

This reminder notice only applies to Base Node operators on mainnet. If you're not operating a Base Node on mainnet, no action is needed. Base will continue to operate as usual without issue during the upgrade.

Monitoring - Blockscout and Basescan are currently experiencing intermittent issues alongside elevated network throughput. Their teams are aware and actively working on a fix.

The Base network itself remains fully operational and unaffected.

If you need an explorer in the meantime, here are a couple of alternative options:
• https://base.thesuperscan.io/
• https://base.dex.guru/

We’ll send updates as we receive confirmation that the issues have been resolved.
