## Updates from Temporal Cloud
### 2026-05-15 18:30 UTC: resolved
A change to the Cloud UI caused a breaking change to the codec server endpoint. This impacted the UI for some customers for roughly 1.5 hours between May 15, 2026, 11:42:57 AM PDT and May 15, 2026 1:14:53 PM PDT. The change was rolled back and the UI is back to normal operating conditions.
