Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident related to Pokemon Sword and Shield causing Roku devices to crash and get stuck in a boot loop has happened again within the same organization. Roku confirmed the issue and mentioned that they are rolling out a software update to resolve it [92451]. (b) There is no information in the provided article indicating that a similar incident has happened before or again at other organizations with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident in this case is related to the design phase. The issue with Pokemon Sword and Shield causing Roku devices to crash and get stuck in a boot loop is attributed to the games' Y-Comm service constantly searching for other Pokemon players on the same wireless network and online. This behavior of the game's service causes Roku devices to mistake Pokemon's data for its own data packets, leading to the crash because they can't read it [92451]. (b) The software failure incident is also related to the operation phase. Users experiencing the issue were advised by Roku to set their Nintendo Switch console to airplane mode to cut it off from the network while waiting for the software update to resolve the problem. Additionally, Roku provided instructions on what to do if the device restarts when playing the new Switch game, indicating operational steps to address the issue [92451].
Boundary (Internal/External) within_system (a) The software failure incident involving Pokemon Sword and Shield causing Roku devices to crash and get stuck in a boot loop is primarily within_system. The issue is caused by the games' Y-Comm service constantly searching for other Pokemon players on the same wireless network and online, leading to Roku devices mistaking Pokemon's data for its own data packets and crashing as a result [92451]. The solution provided by Roku involves rolling out a software update to affected users and manually checking for updates to resolve the issue, indicating that the problem originates within the system and can be addressed through software updates and settings adjustments.
Nature (Human/Non-human) non-human_actions (a) The software failure incident in this case was due to non-human actions. The issue was caused by the Pokemon Sword and Shield game's Y-Comm service constantly searching for other players on the same wireless network, which led to Roku devices mistaking Pokemon's data for its own data packets and crashing as a result [92451].
Dimension (Hardware/Software) hardware, software (a) The software failure incident in this case occurred due to hardware-related issues. The problem was caused by the games' Y-Comm service constantly searching for other Pokemon players on the same wireless network and online, which led to Roku devices mistaking Pokemon's data for its own data packets and crashing as a result [92451].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident in this case is non-malicious. The issue between Pokemon Sword and Shield and Roku devices was not caused by any malicious intent but rather by a technical compatibility problem between the game's Y-Comm service and the Roku devices on the same network. The Y-Comm service was constantly searching for other Pokemon players on the wireless network, causing Roku devices to mistake Pokemon's data for its own data packets, leading to crashes and boot loops [92451].
Intent (Poor/Accidental Decisions) accidental_decisions (a) The software failure incident related to the Pokemon Sword and Shield game causing Roku devices to crash and get stuck in a boot loop was not due to poor decisions but rather an accidental decision. The issue was caused by the game's Y-Comm service constantly searching for other Pokemon players on the same wireless network and online, which Roku devices mistakenly interpreted as their own data packets, leading to the crash [92451].
Capability (Incompetence/Accidental) accidental (a) The software failure incident in this case seems to be more related to accidental factors rather than development incompetence. The issue arose from the interaction between the Nintendo Switch game Pokemon Sword and Shield and Roku devices, specifically due to the games' Y-Comm service constantly searching for other players on the same wireless network. This caused Roku devices to crash and get stuck in a boot loop as they mistook Pokemon's data for their own data packets [92451]. The incident was not a result of development incompetence but rather an unintended consequence of the game's network behavior conflicting with Roku devices.
Duration temporary The software failure incident reported in Article 92451 is temporary. The issue causing Roku devices to crash and get stuck in a boot loop when connected to the Nintendo Switch game Pokemon Sword and Shield is due to the game's Y-Comm service constantly searching for other players on the same network. This issue is specific to the interaction between the game and Roku devices, leading to the temporary failure experienced by impacted users. Roku confirmed the issue and provided instructions for users to resolve the problem through a software update or by temporarily disconnecting the Nintendo Switch from the network [92451].
