Maintenance:
One of the significant benefits of using Cambrig Exchange Hosting Company is the fact that you never have to pay for new software versions or system improvements. To bring you these benefits, we usually schedule a monthly late-night maintenance in which we upgrade the existing system for enhancements and other updates. From time to time, we also schedule emergency maintenance usually in response to security concerns. We typically initiate these maintenance activities during the non-peak 21:00 - 05:00 U.S. Eastern Standard Time hours to minimize downtime. For non-emergency maintenance, you will receive at least a two (2) day notice. For emergency maintenance, you will receive at least a twelve (12) hour notice. We also reserve the right to perform immediate emergency maintenance without any prior notification, should it be deemed absolutely necessary to protect and maintain the security of the service.
