MCS Network Outage to continue

The unexpected power issue that caused this outage has caused a failure in a critical component of the MCS router. We’re currently working with CIS on getting this back online, either with a replacement supervisor card, or an ad-hoc temporary solution until a replacement can be installed. We’re currently estimating another couple of hours of downtime.
This outage is affecting all wired hosts on MCS networks, including most servers with a .mcs.anl.gov address.
Hosts on wifi can talk to other Argonne and external hosts. If your machine is wifi capable, that is the recommended workaround for now.
