When a local network event takes place, often IT resources get solely placed into troubleshooting and healing the network. This is a great primary action but consider and start moving a Plan B in the event that healing the network does not work. Restoring from backup to a different server may not seem like a great plan now.

This can decrease downtime experienced and will often show areas that can be improved for Business Continuity Planning. |
