Internet and online server instability is ruining the digital experience. Give production users access to a server on the local network that is a copy of their remote servers. Use syncing software to keep the copies exact.
Qualitative costs can be calculated on the reduction of downtime. Vaults are already designed for servers for added security. Locally installed clients and web based applications can be configured to access the local server instead of the remote internet server.
This can also be summarized by saying give production users access to a live backup copy.
The largest gripe in our office is no access. The most common email we receive is XXX is down.
