We will be conducting a disruptive maintenance on Saturday into Sunday morning this weekend.  We are installing an additional new qfx5100 switch as well as migrating members from the old switch.  We do not expect the switching fabric to be disrupted for very long but it is possible for some peers to remain down for 30min-60min within the window.  In parallel we will also be taking down the route server VMs and hypervisors for updates and patches, this process may take some time if disk checks are needed.
