Base Mainnet | Intermittent transaction confirmation latency
Resolved - This incident has been resolved.
May 17, 19:45 UTC
Update - The network has been functioning well over the past few days, we've implemented fixes and improvements to transaction processing pipelines, and we're closely monitoring the situation to ensure smooth performance going forward
May 17, 15:39 UTC
Update - Follow-up for Node Operators

If your node has fallen behind, please review our performance tuning recommendations:
https://docs.base.org/chain/node-performance

Still seeing issues after applying those changes? Reach out in the #node-operators channel of the Base Discord (https://base.org/discord)—we’re happy to help.
May 14, 17:00 UTC
Monitoring - We're currently observing some localized delays in transaction confirmation due to increased activity and dynamic fee conditions. The network is processing transactions normally, but some may take longer than expected to be included.

We're closely monitoring the situation to ensure smooth performance across the board.

If you're seeing delays, please make sure you're using competitive fees and have retry logic in place for time-sensitive operations.

Sepolia flashblocks websocket endpoint rate limiting
Resolved - This incident has been resolved.
May 17, 00:23 UTC
Update - We are continuing to investigate this issue.
May 16, 22:17 UTC
Investigating - Confirmed reports that wss://sepolia.flashblocks.base.org/ws is returning 429 (Too many requests) or 404 (Not Found), we're aware and investigating the issue.

Base Mainnet | Canonical Bridge Maintenance
Completed - The scheduled maintenance has been completed.
May 14, 15:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
May 14, 14:30 UTC
Scheduled - On May 14th at 14:30 UTC, the Optimism Collective will conduct a 30-minute pause of canonical bridge withdrawals across Superchain mainnets, including Base mainnet. This is routine maintenance and all funds are safe.

Mainnet users will see no impact, unless they are actively attempting to withdraw via a canonical bridge during the pause window. If so, they’ll simply need to resubmit their withdrawal after the pause. There are no funds at risk, and no other action is required.

All other mainnet activity will continue as usual.

Base Mainnet | Upgrade 15: Isthmus Hard Fork
Completed - The scheduled maintenance has been completed.
May 9, 17:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
May 9, 16:00 UTC
Scheduled - 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:

Planned Gas Target Increase to 35 Mgas/s
Completed - The scheduled maintenance has been completed.
May 7, 19:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
May 7, 17:00 UTC
Scheduled - Base is increasing the per block gas target from 32.5 Mgas/s to 35 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: 35 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: 3.8TB
* Geth full: 10.3TB

✅ 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.
