MassiveGRID will perform any necessary preventative maintenance across all the customers’ hosted infrastructure. Additionally, we will replace defective or failed hardware upon detection. Considering that MassiveGRID uses High Availability architecture with at least N+1 redundancy on all Network, Hardware & Power elements, this will be totally transparent to our customers with zero downtime. This transparency & zero downtime is also applicable, in case our customers decide to Upgrade their package in terms of CPU cores, RAM size, Disk Space Capacity, etc. This is done instantly, as soon as the order goes through billing successfully. (Please note that Disk Space Capacity can only increase, not decrease).
