## Updates from Sauce Labs
### 2026-06-18 06:12 UTC: monitoring
We have been experiencing device unavailability in our EU-Central-1 data center and have identified the root cause. We have taken remedial action and are currently monitoring.

### 2026-06-18 06:59 UTC: resolved
After taking remedial action, we are now seeing real devices available for testing in the EU-Central-1 data center. All services are fully operational.

### 2026-06-18 07:30 UTC: investigating
Around 3:51 AM UTC we started experiencing lower iOS device availability in the EU-Central data center. Our team is actively investigating the root cause and working toward a resolution.

### 2026-07-06 17:17 UTC: postmortem
Dates:
Thursday June 18 2026, 03:45 UTC - 06:45 UTC.
What happened:
Approximately 7% of iOS devices in our EU data center were temporarily unavailable for customer test sessions after a loss of power to the rack hosting them.
Why it happened:
The power circuit feeding the affected rack exceeded its capacity, and a protective breaker tripped to safeguard the line - cutting power to the devices on that rack until the circuit was restored.
How we fixed it:
The affected circuit was reset and power restored to the rack, returning the devices to customer service.
What we are doing to prevent it from happening again:
We are redistributing power load across affected racks, adding capacity monitoring with early-warning alerts ahead of circuit limits, and introducing a capacity review before new devices are deployed to a rack.
