| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident occurred due to non-human actions, specifically a recent update to the service that was blamed for causing the outage. Microsoft mentioned on Twitter that the update would be rolled back to mitigate the issues [105484]. |
| Dimension (Hardware/Software) |
software |
(a) The software failure incident occurring due to hardware:
- The article does not mention any specific hardware-related issues contributing to the software failure incident. It primarily focuses on authentication issues in Microsoft's cloud-based office services, which were attributed to a specific portion of the infrastructure not processing authentication requests in a timely manner [105484].
(b) The software failure incident occurring due to software:
- The software failure incident was primarily attributed to a recent update to the service, which Microsoft blamed for causing the outage. The company mentioned that the update would be rolled back to mitigate the issues [105484]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident in this case was non-malicious. Microsoft attributed the outage to a specific portion of their infrastructure not processing authentication requests in a timely manner, which led to issues with logging into online services like Teams, Outlook, and Office [105484]. Additionally, Microsoft mentioned that the outage was caused by a recent update to the service, which they planned to roll back to mitigate the issues [105484].
(b) The software failure incident was not malicious, as there is no indication in the articles that the outage was caused by any intentional actions to harm the system. |
| Intent (Poor/Accidental Decisions) |
poor_decisions |
(a) The software failure incident related to the outage of Microsoft's cloud-based office services, including Teams, was attributed to a recent update to the service. Microsoft mentioned on Twitter that the outage was caused by a recent update and that rolling back the update would help mitigate the issues [105484]. This indicates that the failure was due to poor decisions related to the update that caused authentication issues and impacted users worldwide. |
| Capability (Incompetence/Accidental) |
development_incompetence, accidental |
(a) The software failure incident can be attributed to development incompetence as Microsoft mentioned that a recent update to the service caused the outage, and they planned to roll back the update to mitigate the issues [105484].
(b) Additionally, the incident can also be categorized as accidental as Microsoft stated that a specific portion of their infrastructure was not processing authentication requests in a timely manner, leading to the outage. They were pursuing mitigation steps and rerouting traffic to alternate systems to provide relief to affected users [105484]. |
| Duration |
temporary |
(a) The software failure incident in this case was temporary. Microsoft reported issues with authentication for its cloud services at around 9.25pm UTC, affecting services like Teams, Outlook, and Office worldwide. The company mentioned that a specific portion of their infrastructure was not processing authentication requests in a timely manner, and they were pursuing mitigation steps for the issue. By 3am UTC, Microsoft reported that the services were mostly restored, although a small subset of customers in North America and Asia Pacific were still facing issues accessing the services [105484]. |
| Behaviour |
crash, other |
(a) crash: The software failure incident in the article can be categorized as a crash. Microsoft's cloud-based office services, including Teams, experienced an outage where users were having issues logging in, and the system was not processing authentication requests in a timely manner, leading to a loss of service functionality [Article 105484].
(b) omission: There is no specific mention of the software failure incident being related to omission in the article.
(c) timing: The software failure incident is not related to timing issues where the system performs its intended functions but too late or too early.
(d) value: The software failure incident is not related to the system performing its intended functions incorrectly.
(e) byzantine: The software failure incident is not related to the system behaving erroneously with inconsistent responses and interactions.
(f) other: The behavior of the software failure incident can be described as a system outage impacting Microsoft's cloud-based office services, including Teams, due to issues with authentication processing, leading to a disruption in service availability [Article 105484]. |
