Incident Report for VitalSource

Postmortem

On September 29, 2021, from about 3:59 PM Eastern, till about 5:03 PM Eastern, we experienced service degradations across several systems at VitalSource. This issue originated with one of our production data storage systems. The system, which supports our Core services, started experiencing very high I/O, which severely impacted our ability to service requests. We stabilized the system by increasing I/O capacity and reconfiguring background services that generate load on these systems.
