SERVICE OUTAGES

UNPLANNED CS SERVICE OUTAGES

WHAT: Issues with NIS and NFS affecting our services. WHEN: Started around 2:40pm

We are seeing various errors affecting two of our major services, NIS (for account and related information for our systems) and NFS (accessing our user directories and app directories.) There is still access to our systems, it seems, but certain services look to be having issues.

We are investigating the issues now and will update shortly.



PLANNED CS SERVICE OUTAGES

WHAT: Major CS Grad/Research Net (and some Ugrad) IT services outage, as we update our file server and our mail server.
WHEN: Wednesday, June 7, from 5am to approx 8am.
DETAILS: Our CS Grad/Research Net home directory file server, rtfm.cs.jhu.edu, and our mail (and other services) server, blaze.cs.jhu.edu, will both be shut down so that filesystem-related updates can be applied. We will apply these updates on Wednesday, June 7, from 5am to approximately 8am.
During the process of applying updates, several of our CS services will be unavailable. If there are any unexpected complications during the update process that will delay the restoration of services, we will update this CS IT Support Wiki's Notices page.

Suspended (Unavailable) Grad/Research Net services while rtfm.cs.jhu.edu & blaze.cs.jhu.edu are down:

  • CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users.
  • Incoming mail should be queued by the sender until our mail service is back up again. Outgoing mail will not be available.
  • IMAP, POP, and Webmail from our CS (Grad/Research Net) Mail server will be unavailable.
  • Some CS webpages, including user (and possibly lab and other CS pages), will be unavailable.
  • Grad/Research Net user accounts/home directories will be inaccessible during the downtime.
  • SMB File Shares (CS Office Staff uses these) will be unavailable.
  • ssh service to our CS Grad/Research Net Linux boxes (masters1 through masters16, gradx, and gradz) will be unavailable.
  • Console (desktop) access to masters1 through masters16 will be unavailable.
  • MySQL service via the mysql.cs.jhu.edu server will be unavailable.
Note to Ugrad Net users: During the rtfm.cs.jhu.edu and blaze.cs.jhu.edu updates, email directed to your ugrad acct @cs.jhu.edu will not be immediately delivered. Other Ugrad Net services should remain available.
