Elevated API errors between 9:30-11:30am PT on 30th Sept.

Resolved Sep 30, 2025 at 7:11pm UTC

We experienced intermittent spikes in 5xx errors on our APIs in the weekly cluster. The root cause was identified, and a fix has already been implemented.

During this period, both inbound and outbound calls may have been affected, as they rely on the APIs for data, resulting in potential service degradation.

TL;DR

On August 4th, an incident occurred due to aggressive pod consolidation by Karpenter, which caused Redis pods to be evicted and restarted.

Incident Report:
Increased call failures on July 25 (PST)

The fallback service for short calls (our serverless workers) could not start because its image architecture didn’t match the configured runtime (image built for ARM64, runtime set to x86). We stabilized the platform by scaling primary workers and then corrected the configuration. Service is o...
