The main problem in our area are ice storms, freezing rain, severe thunderstorms and tornados. Most of these result in power outages which is dealt with by UPS and backup generators. Now our company has experienced growth over the past decade to the point where we are now beginning to implement 2 co-locations for our datacenters with failover in case of disaster. We have always had a disaster recovery plan which we test twice a year by recovering our environment at a remote site, but having the co-locations with replication and failover will reduce our recovery time considerably. The best advice for having your datacenter prepared for severe weather is following the Boy Scout motto and always be prepared!
