## Updates from Braintrust
### 2026-08-19 18:01 UTC: monitoring
The upstream APT package mirror on AWS us-east-1 is degraded. \*\*There is currently no downtime\*\* and we are looking into alternative package mirrors in the meantime.
Please note that for \*\*both the Braintrust-hosted data plane and self-hosted data planes:\*\*
EC2 instance replacement due to healthcheck failures or deploys may result in failed instance initialization and downtime until the upstream issue is resolved.

### 2026-08-19 22:35 UTC: resolved
The upstream APT package mirror in AWS us-east-1 has recovered and we're no longer seeing impact when starting new brainstore instances.
