Business leaders must prepare for disasters made by man or Mother Nature with extensive, practiced recovery plans to avoid system shutdowns.

A Delta ground stop was lifted Monday morning following a 2:30 a.m. ET power outage in Atlanta that delayed and cancelled flights worldwide. Businesses should view this as a cautionary tale, highlighting the importance of quality data center power and disaster control systems.

Delta cancelled approximately 300 flights due to the outage. As of 10:30 a.m. ET, it operated 800 of its nearly 6,000 scheduled flights. However, Delta customers heading to the airport on Monday should still expect delays and cancellations, according to a press release. As inquiries are high and wait times are long, there may also be some lag time in the display of accurate flight status from the airline, it warned.
