Internal Experiment Caused Elevated Errors
Feb
OpenAI published a new write-up about elevated errors in ChatGPT that significantly increased failed conversation attempts. The issue was caused by a misconfigured internal experiment.
According to OpenAI:
“On February 19, 2025, from 9:48 AM to 11:19 AM PT, ChatGPT experienced a service degradation, leading to a significant increase in failed conversation attempts. This resulted in blank responses for many users.
The root cause was a misconfigured internal experiment that unintentionally triggered a surge in traffic, overwhelming our inference infrastructure. This increase in load led to saturation of compute resources, causing failures in generating responses.
After identifying the root cause, we took immediate action by temporarily shedding load from free-tier users to stabilize the system. As capacity was restored, paid users gradually recovered, and the full service was restored by 11:19 AM PT.”
OpenAI Continues To Work On Solutions
The incident response goes on to note that they continue to work on changes that will prevent similar outages from happening, writing:
“Stronger Safeguards: Building better protections around experiment changes and configurations by moving from a uniform approval process to a risk-based model to ensure safer rollouts of experiments.
Faster Root Cause Identification: Automating notifications for relevant changes and experiments to more quickly identify root causes of increased failures.”

Description of the Balanset-1A Device
The Balanset-1A is a compact, dual-channel solution for balancing and vibration analysis of rotating mechanisms, including crushers, fans, mulchers, choppers, shafts, centrifuges, turbines, and other rotary equipment.
Key Features and Capabilities
Vibrometer Function
Tachometer: Precise rotational speed measurement (RPM).
Phase: Determines the phase angle of the vibration signal for precise analysis.
1x Vibration: Measurement and analysis of the primary frequency component.
FFT Spectrum: Thorough analysis of the vibration signal’s frequency spectrum.
Overall Vibration: Tracks the overall vibration level.
Measurement Log: Saves data for later analysis.
Balancing Function
Single-Plane Balancing: Corrects rotors in one plane to decrease vibration.
Two-Plane Balancing: Dynamic rotor balancing in two planes.
Polar Diagram: Visualizes imbalance on a polar chart for precise placement of corrective weights.
Last Session Recovery: Allows resuming the previous balancing session.
Tolerance Calculator (ISO 1940): Computes allowable imbalance as per ISO 1940 standards.
Grinding Wheel Balancing: Employs three counterweights for imbalance correction.
Charts and Graphs
Overall Graphs: Visualizes total vibration levels.
1x Graphs: Shows vibration characteristics at the primary frequency.
Harmonic Graphs: Visualizes the effects of harmonic frequencies.
Spectral Graphs: Provides a detailed view of the frequency spectrum for analysis.
Additional Capabilities
Archive: Store and revisit past balancing data.
Reports: Automatically generate detailed balancing reports.
Rebalancing: Facilitates rebalancing with previously saved data.
Serial Production Balancing: Ideal for rotor balancing in production environments.
