Backup power keeping the network going while we sit in the dark

So often people focus on the negatives. However, I have noticed that during the current prolonged power outage in Pretoria East, that many of the cellphone towers have additional, portable backup power generation in place. This would be in addition to the batteries that would be on site for the relatively short term power outages. Clearly a disaster recovery plan is in place and has been executed before the network falls over in the affected areas. I am not sure which of the networks has provided this backup plan, but it appears that the networks are working together to solve this potential problem before the masses have yet another reason to complain. Well done Mobile Networks and thanks for keeping us connected while we sit in the dark!
