Type of Work : Teting
Purpose of Work : Redundancy
Locations of Work : Charlotte Datacenter
Impact of Work : Possible Brief Outage

Charlotte Datacenter will be performing routine maintenance designed to test the redundancy of network. Typically we perform such tests every quarter and on a smaller scale. However due to recent software upgrades we will be performing a broader, more thorough simulation. We will be simulating failures at different layers and devices to determine whether our designs and redundancy protocols are performing as expected. There should be no visible evidence of these tests other than you may see alternate paths being used in a traceroute. There should be no packet-loss or added latency at any time. In the event we find a device or segment of our network not performing as expected we will be reverting any changes we have made and will be scheduling maintenance to correct the issue at a later date.

69.59.xx.xx & 76.76.xx.xx servers will be affected.
