We've rolled out infrastructure improvements to strengthen runtime stability across regions, including NYC, after identifying DNS-related instability under load.

What's improved:

- DNS resilience under network partitions
- More powerful instance types and tuning of runtime resource allocations improve performance alongside noisy neighbours
- Improvements to runtime monitoring and alerting

These changes reduce DNS-related latency, improve cold start reliability, and minimize blast radius during node-level issues.
