** Maintenance Announcement – ESXi Compute host replacement**

We are replacing approximately 50% of our Compute hosts with new hardware. We do not anticipate any downtime, however we will be causing a significant number of vMotion events. We will be adding and removing hosts, it has been planed out that we will not be increasing memory pressure and twords the end it will decrease as our overall memory capacity increases.

We will be performing scheduled maintenance on the name servers. Only one name server will be taken down at a time to minimize any potential impact. Each host will be unreachable for approximately 5 minutes while maintenance is in progress and the system is rebooted.

Any services hard-coded to a single name server will likely experience issues until that name server is restored.

Cyder will continue to be available although any changes will not be pushed live until the maintenance is complete.
