On December 7, 2021, Amazon Web Services (AWS) experienced a significant outage lasting nearly seven hours, which disrupted not only its own services but also those of third-party platforms like Netflix and Disney+. A Root Cause Analysis by AWS revealed that congestion and inadequate monitoring visibility were central to the delayed resolution, as the internal operations teams were unable to pinpoint the source of the issue. The incident highlighted the critical nature of monitoring systems, emphasizing that monitoring gaps contribute to prolonged outages. Effective monitoring requires a resilient and distributed approach, such as using multiple monitoring systems across various regions or providers to ensure visibility and reduce dependencies on affected infrastructure. This strategy was exemplified by Logz.io, which operates across eight AWS regions and was able to maintain functionality during the outage by relying on unaffected regions. The incident underscores the importance of robust monitoring practices in maintaining service continuity in the cloud-dependent business landscape.
