Stan Gibson does a good job of reporting on the impact among service provider employees and their companies of the July 11, 2006 Mumbai bombings that killed 200 commuters in this eWeek article.
According to Gibson, "outsourcing providers in Mumbai scrambled to make sure employees and customer data were safe and secure. Meanwhile, outsourcing customers sought reassurances that their Indian partners could handle future unforeseen events."
Thankfully, personal tragedies were minimal among this population of workers. Also, business continuity plans kicked in and kept operations running.
