one_organization |
(a) The software failure incident at CERN with the Large Hadron Collider due to an electrical fault causing a liquid helium leak is specific to CERN and has not been reported to have happened again within the same organization [25410].
(b) There is no information in the provided article about a similar incident happening at other organizations or with their products and services. |
| Phase (Design/Operation) |
design |
(a) The software failure incident at CERN's Large Hadron Collider was primarily due to a design issue. The incident was caused by an electrical fault in the system, leading to a liquid helium leak that damaged various components of the particle accelerator. The fault originated from a resistive zone in one of the electrical connections, which created an electrical arc, puncturing a helium enclosure and causing subsequent damage [25410].
(b) There is no specific information in the provided article indicating that the software failure incident was due to factors introduced by the operation or misuse of the system. |
| Boundary (Internal/External) |
within_system |
The software failure incident at CERN's Large Hadron Collider was primarily within_system. The incident was caused by an electrical fault within the system, specifically a resistive zone in one of the electrical connections that led to an electrical arc puncturing a helium enclosure around a magnet, resulting in a helium leak and subsequent damage to the system components [25410]. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident at CERN's Large Hadron Collider was not directly attributed to non-human actions. The incident was caused by an electrical fault that led to a liquid helium leak, damaging the superconducting magnets and other components of the particle accelerator [25410].
(b) The software failure incident at CERN's Large Hadron Collider was a result of human actions indirectly leading to the failure. The electrical fault that caused the helium leak was likely a result of human errors in the design, maintenance, or operation of the equipment, as it involved an electrical connection developing a resistive zone that led to the leak and subsequent damage [25410]. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident occurring due to hardware:
- The incident at CERN's Large Hadron Collider was caused by an electrical fault that led to a liquid helium leak, damaging the superconducting magnets and other components [25410].
(b) The software failure incident occurring due to software:
- The articles do not mention any software-related contributing factors to the failure incident at CERN's Large Hadron Collider. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident at CERN's Large Hadron Collider was non-malicious. The incident was caused by an electrical fault that led to a liquid helium leak, resulting in damage to the superconducting magnets and other components of the particle accelerator [25410]. |
| Intent (Poor/Accidental Decisions) |
unknown |
The software failure incident at CERN's Large Hadron Collider was not directly related to software issues but rather to an electrical fault that caused a liquid helium leak. The incident was attributed to an electrical fault that caused a resistive zone in one of the electrical connections, leading to an electrical arc that punctured a helium enclosure around a magnet [25410]. This indicates that the intent of the software failure incident was not due to poor decisions or accidental decisions but rather a technical fault in the electrical system. |
| Capability (Incompetence/Accidental) |
unknown |
The articles do not mention any software failure incident related to development incompetence or accidental factors. |
| Duration |
temporary |
The software failure incident at the Large Hadron Collider (LHC) was temporary. The incident was caused by an electrical fault that led to a liquid helium leak, damaging the magnets and support structures in the LHC. The need for repairs has put the experiment out of action until at least summer 2009, indicating that the failure was temporary and not permanent [Article 25410]. |
| Behaviour |
other |
(a) crash: The software failure incident at CERN's Large Hadron Collider was not specifically described as a crash in the articles. The incident was primarily attributed to an electrical fault causing a liquid helium leak, leading to damage to the superconducting magnets and other components of the particle accelerator [Article 25410].
(b) omission: The software failure incident did not involve the system omitting to perform its intended functions at an instance(s) as the primary cause was related to an electrical fault and subsequent helium leak [Article 25410].
(c) timing: The software failure incident was not related to the system performing its intended functions too late or too early. Instead, the incident was caused by an electrical fault leading to a liquid helium leak and subsequent damage to the particle accelerator components [Article 25410].
(d) value: The software failure incident did not involve the system performing its intended functions incorrectly in terms of the software itself. The incident was more related to a hardware issue caused by an electrical fault and subsequent helium leak [Article 25410].
(e) byzantine: The software failure incident did not exhibit characteristics of a byzantine failure where the system behaves erroneously with inconsistent responses and interactions. The incident was primarily attributed to a specific electrical fault causing a helium leak and subsequent damage to the particle accelerator components [Article 25410].
(f) other: The software failure incident at CERN's Large Hadron Collider was primarily caused by an electrical fault leading to a liquid helium leak, resulting in damage to the superconducting magnets and other components. The incident did not exhibit behaviors such as a crash, omission, timing issue, or byzantine behavior in the software itself [Article 25410]. |
