All UCAR hosted Vidyo systems are now shut down.
Please remove Vidyo clients and references to the UCAR hosted Vidyo system which is now decommissioned.
Let me know if questions.

Given UCAR is shifting to Google Hangouts and other room based systems for videoconferencing needs, support for Vidyo at UCAR will stop on Tuesday, 31-Mar-2015.

If you haven't already, we encourage Vidyo users to visit


as well as


to familiarize themselves with Google Hangouts and Vidyo alternatives using UCAR/Google solutions.
We are targeting deactivation of ALL Vidyo components currently housed at UCAR so after 31-Mar-2015, Vidyo clients will no longer work and all VidyoPortals will no longer be available.

Also VidyoReplay will also be shut down so if you have any recordings on the VidyoReplay server that you would like to keep, please download them as soon as possible.

Please let us know at vidyo@ucar.edu if anyone has questions about Vidyo equivalencies under the new UCAR/Google offerings or a need for the Vidyo system to extend past March 2015.

Service Outage Information:

The following services will be down during the NCAR Spring 2015 power down. Additional information and notifications will be provided via the Notifier service leading up to the power down.

* DNS: the DNS servers at ML, both internal and external, will be down, but DNS servers at NWSC will remain up, so the DNS impact should be minimal.
* LDAP: Both ldap.ucar.edu and ldaphpc.ucar.edu LDAP servers will be down.
* DHCP: the CISL DHCP server at ML will be down, which means that connecting to most wireless and guest networks will not be possible.
* UCAR Campus Network: The "UCAR Internal" and "Eduroam" wireless networks will be out of service (until the end of the maintenance period).
* Token Authentication: The radius servers at ML will be down. This means new VPN connections cannot be established, and token authentication on hosts in Boulder will not work. At NWSC, NWSC-based staff and university users will be able to authenticate to NWSC resources, but most Boulder-based staff will not.
* Mail: Google mail services, which includes mail to user mailboxes and aliases, will not be affected. The Mailman system, and mail to a few mailboxes inside UCAR, will be down.
* The license servers for Mathematica, Matlab and the PGI compilers will be down.
* UCAS Password Changes: Changing UCAS passwords via the web (kpasswd.ucar.edu) will be unavailable.
* UCAR web services: web, jira, drupal, wiki.ucar.edu, etc, will be down.
* ExtraView (CISL helpdesk ticketing system) will be down. - Please contact CASG at x4300 or 307-996-4300.
* ML private network access via ipmi01.ucar.edu and ipmi02.ucar.edu will be unavailable.
