We plan to start this network upgrade as per schedule at 11:30PM
The maintenance window is actually going to last for 90 minutes. During the next 90 minutes (i.e. uptil 1AM EST) we will be switching routes and each subnet is going to experience an outage of about 2 minutes each.
Hence, the actual downtime experienced by customers would not exceed 2 minutes..
We thank our customers for their cooperation. As we grow, we need to expand our network capacity and this switch is a step in that direction
