PLANNED CS IT SERVICE OUTAGES

WHAT: Most CS IT services will be unavailable due to file server maintenance.

WHEN: Tuesday, December 27, 9:00 am to 12:00 pm


DETAILS: We will be performing maintenance on our several of servers. This will require downtime for several major CS IT services. The affected IT services will be unavailable on the morning of Tuesday, December 27, starting at 9:00 am. Most services should be restored before 10:00 am, but services depending on the ugrad file server will remain unavailable for longer. Please see below for the list of affected services.

CS IT Services That Will Not Be Available During The System Maintenance:

  • CS mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users. 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 Net users. CS ugrads can send through the JHU mail server, which will remain available. We expect mail service to be restored by 10:00 am, but see below about mail retrieval for ugrad accounts.
  • IMAP, POP, and webmail (for both Grad/Research and Ugrad accounts) will be unavailable. We expect Grad Net email to be full operational by 10:00 am. Ugrad IMAP, POP, and webmail should be available by 12:00 pm.
  • No locally-stored CS webpages will be available. The main CS website (run by WSE) will remain available, but some individual pages may fail to load. Personal webpages (both grad and ugrad) will not load. Other websites hosted by us for department affiliates (e.g. lab websites) will be unavailable. The CS IT Support Wiki and its Notices page will remain available. We expect all service interruptions for the main webserver (www.cs.jhu.edu) and hosted websites to be completed before 10:00 am. Ugrad personal webpages should be available again by 12:00 pm.
  • Grad/Research Net and Ugrad Net user accounts and home directories will be inaccessible during the services outage. We expect Grad Net services to be restored by 10:00 am and Ugrad Net services by 12:00 pm.
  • ssh service to our CS Grad/Research Net & Ugrad Net Linux boxes (masters1 through masters16, ugrad1 through ugrad24, gradx, gradz, ugradx,and ugradz) will be unavailable. We expect Grad Net services to be restored by 10:00 am and Ugrad Net services by 12:00 pm.
