A few years ago when I was working on the weekend we had an incident, as a call center supervisor that works on weekends we don’t do much we just make sure everyone is where they need to be and taking calls. One Saturday morning during the summer, the office started to get hot and our system applications stopped working. Nobody was able to receive any calls nor were we able to access the internet. Come to find out that the cooling system in the Data Center had blown a fuse and stopped working, everything started to overheat, and I think there was an automatic override that shut everything down. It took a while to get everyone on board, once everyone figured things out they were able to switch us over to one of our other locations and get us back up and working. That is when I found out that we had more than one location that kept our data and was used as a backup system for situations like this. Once I started learning about redundancy it made more sense as to why this is needed, especially in a business like ours where we support online banking for many different banks. Downtime was minimal thanks to having a second data center and having all of our systems back up to that center. Eventually, they moved our data center to a different location altogether, and even then they switched us over and then proceeded to disconnect everything pack it up and moved. It surprises me when I hear about companies that don’t have a backup to their systems, regardless of how big or small the company is. If I ever get to the point where I have my own company, I will definitely have a redundant amount of backups.
