Hi all,

I am working with a client that wishes to implement ArcGIS Enterprise 11.3 on-premise or cloud or hybrid and achieve 99.999% ( five 9s) of the uptime (equates to ~5 minutes outage per year). Is this even possible? Is there any online documentation on what may be needed to achieve this?

Thanks,
