The no-context constraint is what makes this hard.
Start by acknowledging the ambiguity and showing ownership: immediately gather more information from the customer and internal dashboards to assess impact and scope. Then methodically trace the issue through logs, metrics, and code, while proactively building a network of potential stakeholders and documenting findings for future reference.
Pro tip: Demonstrate bias for action by proposing a short-term mitigation (e.g., workaround or rollback) while you investigate root cause, and emphasize documenting your learnings to fill the knowledge gap left by the departed engineer.
Contact the customer to get specific details (device model, app version, error messages, steps to reproduce) and check monitoring dashboards to see if this is an isolated incident or a broader outage.
Search internal directories, team wikis, and code repositories for previous owners, related teams, or documentation. Reach out to adjacent teams (e.g., Fire TV, video playback) who might have context.
Based on impact, decide on immediate mitigation: if widespread, consider rollback or feature flag; if isolated, provide a workaround. Communicate status to the customer and stakeholders.
Dive into logs, metrics, and code to trace the failure. Use debugging tools, reproduce locally if possible, and collaborate with any identified experts to pinpoint the issue.
Implement a fix, verify with the customer, and document the root cause, solution, and key contacts. Share learnings with the team to prevent future knowledge gaps.
