On March 20, 2023, a high internal load occurred within the network file system of the Canada region, causing instability in the platform. The root cause was identified as a bug in our server operating system. We rolled back the most recent updates prior to when the bug was introduced which brought stability across the region.
We have identified the primary factor for this incident was a bug in the Ubuntu operating system that was introduced into our environment on March 9, 2023, and has since been removed.
