Scheduled firewall maintenance
Completed - The scheduled maintenance has been completed.
Aug 30, 09:36 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 30, 08:00 UTC
Scheduled - We’ll be performing scheduled firewall maintenance at one of our data centers on August 30, 2026, from 1:00 AM to 4:00 AM PDT. This work may temporarily affect traffic to some Cerebras Inference Cloud endpoints.
We expect any customer-visible interruption to total less than five minutes. However, intermittent unavailability could occur at any point during the three-hour maintenance window. Affected requests may fail or experience increased latency.
We recommend retrying failed requests with exponential backoff and avoiding time-sensitive batch workloads during the maintenance window.
If the work extends beyond the scheduled window, we’ll provide an updated completion estimate.
