:'''WHEN:''' Tuesday, February 24, from 6am to 8am.
  
 +
:'''DETAILS:'''  We need to perform some maintenance on one of our servers.  This will take approximately 2 hours to complete. During this time, several our of Grad/Research Net and Ugrad Net IT services will be unavailable. Below is a list of the services affected...

:'''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.)
 +
 +
*    IMAP, POP, and webmail (for both Grad/Research and Ugrad accounts) will be unavailable.
 +
 +
*    No locally-stored CS webpages will be available. The main CS website (run by WSE) may or may not remain accessible. If you have a personal or lab CS page that we maintain locally in the dept, those will be unavailable. The CS IT Support Wiki and its Notices page will remain available.
 +
 +
*    All CS Linux user accounts and home directories on both the Grad/Research and Ugrad Nets will be inaccessible during the service outage.
 +
 +
*    ssh service to our Grad and Ugrad Linux clients (masters1 through masters16, ugrad1 through ugrad24, gradx, ugradx, gradz, and ugradz) will be unavailable.
 +
 +
*    Console (desktop) access at any of our Linux client systems will be unavailable.
 +
 +
*    SMB (SAMBA) File Shares (the CS Office Staff and some others use these) will be unavailable.
 +
 +
*    MySQL service via the mysql.cs.jhu.edu server will be unavailable.
 +
 +
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
