Background processing usually remains hidden from end users. No need exists for a user to understand what maintenance goes on under the covers of the service. Office 365 delivers service with no fuss to its users, but recently I have noticed some instances when background processes have made themselves felt. Although these are not serious issues, they are a worrying sign of a lack of attention to detail.
Good write up on some of our issues in the last quarter. We've also experienced some other backgrounds tasks failing that are more subtle, like group icons not syncing across all services.
