Updates from Braintrust 2
- 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.
