Issue Status : RESOLVED
Issue Description : Admins may intermittently encounter errors and are unable to access some reports via the Mobile Endpoint Manager
More info : Affected services included but were not limited to:
-Device Services blade
Scope of impact : Any admins serviced through the affected infrastructure may be intermittently impacted.
Final Update : 02/08/2022 10:14:00 AM – Microsoft rolled out a configuration change to some scale units to disable Redis cache throttling, bypassing Redis completely. They have determined via internal testing that impact has been successfully resolved and service has been fully restored.
Root cause : A software defect caused excessive load on our Redis cache resulting in impact.
Next steps : To prevent similar impact in the future, Microsoft are continuing to investigate their software defects and the excessive load it caused on their Redis cache preventing admins from intermittently encounter errors within the Mobile Endpoint Manager.
