Scheduled Maintenance

Jovian Upgrade on Base Sepolia Testnet November 19th at 16:00:01 UTC Nov 19, 2025 16:00-17:00 UTC

On November 19th at 16:00:01 UTC, the Base Sepolia network will undergo the Jovian upgrade.

Operators of Base Sepolia Testnet nodes must upgrade to the latest release of the Base node software here: https://github.com/base/node/releases/tag/v0.14.1

More information about the Jovian upgrade can be found here: https://docs.optimism.io/notices/upgrade-17#breaking-changes-block-header-changes

Mainnet Flashblocks WebSocket Connection Instability
Resolved - We have made improvements to the handling of rate limits in order to provide a more stable endpoint for Flashblocks.
Nov 17, 15:34 UTC
Identified - We have identified bottlenecks with the Websocket endpoints distributing Flashblocks. Between Nov 5-10, several changes were made that reduced connection drops by 50%. However, investigation continues in order to further reduce connection instability and lower the latency in receiving messages.

Updates will be posted here as progress is made.
Nov 12, 05:38 UTC
Investigating - We are currently investigating degraded connection stability to the Base Mainnet WebSocket endpoint for Flashblocks `wss://mainnet.flashblocks.base.org/ws`. Applications and nodes may experience intermittent connection drops to that endpoint.

Base Mainnet Gas Limit increase from 125Mgas/s to 150Mgas/s
Completed - The scheduled maintenance has been completed.
Nov 12, 17:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Nov 12, 15:00 UTC
Scheduled - Base Mainnet gasLimit will increase from 125Mgas/s to 150Mgas/s on Wednesday Nov 12th, between 15:00 and 17:00 UTC.

This will be achieved by setting the gasLimit parameter to 300_000_000 per block, and increasing the 1559 elasticity multiplier from 4 to 5.
*NOTE*: This will result in a lower gasTarget throughput from 62_500_000 to 60_000_000 per block.

Flashblocks Degraded Performance
Resolved - Flashblocks building performance has has returned to expected values.
Nov 12, 05:29 UTC
Identified - We are aware of degraded Flashblocks building, resulting in fewer broadcasted Flashblocks than expected. Users may also experience periodic reorgs of Flashblocks.

Base Mainnet Gas Limit increase from 100Mgas/s to 125Mgas/s
Completed - The scheduled maintenance has been completed.
Nov 6, 21:03 UTC
Verifying - The changes have been made. We're monitoring chain health and activity.
Nov 6, 16:31 UTC
Scheduled - Base Mainnet gasLimit will increase from 100Mgas/s to 125Mgas/s on Thursday Nov 6th, between 15:00 and 17:00 UTC.

This will be achieved by setting the gasLimit parameter to 250_000_000 per block, and keeping the 1559 elasticity multiplier to 4, resulting a gasTarget of of 62_500_000 per block.

Base Mainnet Gas Limit increase from 75Mgas/s to 100Mgas/s
Completed - The scheduled maintenance has been completed.
Nov 4, 15:24 UTC
Scheduled - Base Mainnet gasLimit will increase from 75Mgas/s to 100Mgas/s on Wednesday Oct 29th, between 15:00 and 17:00 UTC.

This will be achieved by setting the gasLimit parameter to 200_000_000 per block, as well as increasing the 1559 elasticity multiplier to 4 in order to maintain the existing gas target of 50_000_000 per block.
