| Recurring |
one_organization, multiple_organization |
(a) The software failure incident having happened again at one_organization:
- In Miami-Dade County, the district experienced cyberattacks that caused glitches during online classes. A 16-year-old student at South Miami Senior High School was arrested in connection with cyberattacks that contributed to the issues [104687].
(b) The software failure incident having happened again at multiple_organization:
- Various school districts across the United States faced technical glitches and software problems on the first day of online classes, including server issues in Philadelphia, a statewide software problem in North Carolina, and difficulties connecting in Seattle [104687]. |
| Phase (Design/Operation) |
design, operation |
(a) The software failure incident related to the design phase can be seen in the article where it mentions that the Virginia Beach school district faced technical difficulties on the first day of classes due to an issue with the cloud-based web filter that the district uses to monitor students' online activity. This issue was a result of the system design and setup, as the district uses this filter as part of its system design to ensure online safety and monitoring [104687].
(b) The software failure incident related to the operation phase is evident in the article where it discusses how online classes in Miami-Dade County were disrupted by glitches for days due to cyberattacks. A 16-year-old student was arrested in connection with cyberattacks that caused these issues, indicating that the failure was a result of the operation or misuse of the system [104687]. |
| Boundary (Internal/External) |
within_system, outside_system |
(a) within_system: The software failure incidents reported in the articles were primarily due to factors originating from within the system. For example, in Miami-Dade County, a 16-year-old student was arrested for cyberattacks that caused glitches in online classes [104687]. Additionally, in Virginia Beach, a cloud-based web filter issue blocked students and teachers from logging in on the first day of classes [104687].
(b) outside_system: The software failures were also influenced by factors originating from outside the system. In Hartford, a ransomware attack targeted the city's servers, including the one managing school bus routes, leading to the delay of the first day of school for nearly 18,000 students [104687]. This external cyberattack disrupted the system's operations and highlighted vulnerabilities in the district's infrastructure. |
| Nature (Human/Non-human) |
non-human_actions, human_actions |
(a) The software failure incident occurring due to non-human actions:
- The article mentions a server problem in Virginia Beach that disrupted the first hours back to school, which was due to an issue with the cloud-based web filter used by the district to monitor students' online activity [104687].
- In Hartford, a ransomware attack targeted some 200 of the city's servers with ransomware, including the one managing school bus routes, leading to the delay of the first day of school for nearly 18,000 students [104687].
(b) The software failure incident occurring due to human actions:
- In Miami-Dade County, online classes were choked by glitches for days due to cyberattacks that were later found to be contributed by a 16-year-old student at South Miami Senior High School [104687]. |
| Dimension (Hardware/Software) |
hardware, software |
(a) The software failure incident occurring due to hardware:
- In Miami-Dade County, online classes were disrupted by cyberattacks that were contributed to by a 16-year-old student [104687].
- In Hartford, a cyberattack targeted some 200 of the city's servers with ransomware, including the one managing school bus routes, leading to the delay of the first day of school [104687].
(b) The software failure incident occurring due to software:
- In Virginia Beach, students and teachers faced technical difficulties on the first day of classes due to an issue with the cloud-based web filter used by the district [104687].
- In Houston, students encountered technical glitches when trying to log into the district's online learning hub, indicating software issues [104687]. |
| Objective (Malicious/Non-malicious) |
malicious, non-malicious |
(a) The software failure incident in Miami-Dade County was malicious, as a 16-year-old student was arrested in connection with cyberattacks that caused glitches in online classes [104687].
(b) Non-malicious software failures were also reported, such as server issues in Philadelphia causing trouble logging on, a statewide software problem in North Carolina, and technical difficulties in Virginia Beach due to a cloud-based web filter issue [104687]. |
| Intent (Poor/Accidental Decisions) |
poor_decisions, accidental_decisions |
(a) The software failure incidents reported in the articles can be attributed to poor decisions made by the school districts and education officials. The lack of guidance from state and federal education officials, the rush to find virtual learning platforms, and the absence of coordinated purchasing plans left many districts unprepared for online learning [104687]. Additionally, the article mentions that some districts faced technical issues due to a lack of sufficient preparation for online learning over the summer, as they were still focused on opening in person until circumstances forced them to switch to remote-only instruction [104687].
(b) Accidental decisions or unintended mistakes also played a role in the software failure incidents. For example, in Miami-Dade County, online classes were disrupted by cyberattacks that were not anticipated on such a large scale, leading to technical difficulties for students and teachers [104687]. The incident involving a 16-year-old student at South Miami Senior High School being arrested for cyberattacks highlights how accidental decisions or malicious actions can contribute to software failures. |
| Capability (Incompetence/Accidental) |
development_incompetence, accidental |
(a) The software failure incidents reported in the articles can be attributed to development incompetence. The articles mention that many school districts faced technical glitches and issues with online learning platforms due to a lack of sufficient preparation for online learning over the summer [104687]. Additionally, the lack of guidance from state and federal education officials left districts on their own to tackle the challenge of finding virtual learning platforms and signing contracts within a short timeframe, leading to technical issues [104687].
(b) The software failure incidents can also be categorized as accidental. For example, in Miami-Dade County, online classes were disrupted by cyberattacks that were not intentional on the part of the school district but were caused by a 16-year-old student who was arrested in connection with the cyberattacks [104687]. Furthermore, in Hartford, a ransomware attack targeted the city's servers, including the one managing school bus routes, forcing the district to delay the first day of school [104687]. |
| Duration |
temporary |
(a) The software failure incidents described in the articles were temporary in nature. These incidents were caused by specific contributing factors such as cyberattacks, glitches, and technical difficulties, rather than being permanent failures due to all circumstances. For example, in Miami-Dade County, a 16-year-old student was arrested for cyberattacks that caused glitches in online classes [104687]. Additionally, in Virginia Beach, a cloud-based web filter issue blocked students and teachers from logging in on the first day of classes, but service was restored before noon [104687]. These incidents highlight temporary disruptions rather than permanent failures. |
| Behaviour |
crash, omission, byzantine |
(a) crash: The articles mention instances of crashes such as a website crash in Houston, a server problem in Virginia Beach disrupting the first day of school, and a server issue causing trouble logging on in Philadelphia [104687].
(b) omission: The articles describe instances where the system omitted to perform its intended functions, such as students being kicked out of class calls or having difficulty connecting to text chats and camera feeds in Seattle [104687].
(c) timing: There is no specific mention of failures related to timing in the articles.
(d) value: The articles do not provide information about failures due to the system performing its intended functions incorrectly.
(e) byzantine: The incident in Miami-Dade County involved deliberate cyberattacks by a 16-year-old student that contributed to glitches in online classes, showcasing a byzantine behavior of the system [104687].
(f) other: The articles do not mention any other specific behaviors of the software failure incident. |
