:'''CS IT Services That Will Not Be Available During The Service Outage:'''
 +
*    CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users. And some CS email services will not be available for CS Ugrad Net users. Incoming mail should be queued by the sender until our mail service is back up again. Outgoing CS mail will not be available to Grad/Research Net users, but since CS Ugrads can send through the JHU mail server, CS Ugrads might still be able to send email during the services outage (just not from our lab computers or compute servers.)

'''MAJOR''' motherboard repair of ''rtfm.cs.jhu.edu'', one of our main CS ''Grad/Research'' Net file system servers, will create up to (but hopefully, much shorter than) 6-hour planned downtime for the Grad/Research Network.  Our hardware service/repair company will be on-site completing repairs.
+
*    All CS Linux user accounts and home directories on both the Grad/Research and Ugrad Nets will be inaccessible during the service outage.

*    Console (desktop) access at any of our Linux client systems will be unavailable.
  
−
* ''Email in or out on the Grad/Research Net will be disabled.''  (Connections to smtp.cs.jhu.edu and pop.cs.jhu.edu will fail during that time.  However, incoming mail to CS should queue at an alternative server.)
+
*   SMB (SAMBA) File Shares (the CS Office Staff and some others use these) will be unavailable.
  
−
* ''Email on the Undergrad Net will be disabled during this time'' (as CS Ugrad e-mail addresses are registered via a server on the CS Grad Net.)

*   MySQL service via the mysql.cs.jhu.edu server will be unavailable.
  
−
* ''DNS will only be available if you've configured your computer with a secondary DNS server.''  If you don't have a secondary server in your computer's DNS defined, please add 128.220.2.7 You may notice a delay in DNS name resolution when falling back to the secondary server.

If there are any unexpected complications during the configuration changes that will delay the restoration of services, we will update the CS IT Support Wiki's Notices page at: https://support.cs.jhu.edu/wiki/Notices
