# Base recovers from AWS-related capacity and batch-submission disruption

> Base Mainnet's production capacity and submission of L2 batches to Ethereum were temporarily degraded, exposing cloud-infrastructure availability as a dependency for timely canonical-bridge settlement and monitoring.

- Type: Market stress
- Stage: Recovery reported
- Evidence: confirmed
- Materiality: material
- Event date: 2025-10-20
- Version: 1, published 2026-08-22 (first published 2026-08-22)
- Advisor-relevant: yes
- Affects: Base canonical bridge (protocol)

## What happened

An AWS outage affected Base infrastructure, reducing network capacity and interrupting batch submission on Mainnet and Testnet until service recovered.

## What changed

Base Mainnet's production capacity and submission of L2 batches to Ethereum were temporarily degraded, exposing cloud-infrastructure availability as a dependency for timely canonical-bridge settlement and monitoring.

## What did not change

The status record did not report a consensus failure, bridge compromise, asset loss, changed custody, or a permanent change to withdrawal or finality mechanics.

## Confirmed

- Base began investigating reduced capacity at 08:23 UTC on October 20, 2025.
- Base identified a major AWS outage as affecting its infrastructure.
- Mainnet batch submission and block production were affected.
- Base reported at 09:50 UTC that batch submission resumed and transaction capacity returned to normal.

## Still open

- The number and duration of affected bridge transactions were not disclosed.
- The retained record does not describe infrastructure redundancy or post-incident remediation.
- The retained status surface is not treated as a complete historical incident archive.

## What it means for an advisor

- Review cloud-provider concentration and continuity assumptions in the Base canonical-bridge memo.
- Confirm that bridge operating procedures distinguish L2 inclusion from L1 batch submission and monitor both during infrastructure outages.
