CS IT STAFF AVAILABILITY

  • The CS IT Support staff is back in Malone Hall. Our group is working a hybrid schedule with some of us working remotely on certain days, while others of our team are on campus.
  • We continue being available M-F, 8:30 to 5pm, but there may be certain times we might be online only.
  • Therefore, please remember to email support@cs.jhu.edu for assistance.
  • Also, please have Zoom available on your device(s), so that we can arrange to contact you using that method, as an alternative to in-person communication.
  • For the time being, Steve DeBlasio, our accounts liaison, is providing a virtual version of his daily office hours for accounts, etc. Email support@cs.jhu.edu for details.


CS IT SERVICE OUTAGES

UNPLANNED CS IT SERVICE OUTAGES

Issue with Grad Net Self-Service File Recovery

  • WHEN: Started around October 30, 2020
  • WHAT: Intermittent errors while using self-service recovery

  • DETAILS: The /users/backup directory used for Self-Service File Recovery on the CS Grad Net Linux clients may be sporadically unavailable, due to a software bug. Although you may still attempt the self-service recovery, until further notice, if you need a file restored and are having issues accessing the /users/backups directory, please request restoration from our offline backups.

    We are working on getting a fix for it, but it might be some time before that fix is available.

    NOTE: Self-Service File Recovery continues to be available on the CS Ugrad Net.


PLANNED CS IT SERVICE OUTAGES

Major CS Grad/Research Net and Ugrad Net IT Services Outage

WHAT: Most CS IT services will be unavailable due to file server maintenance.
WHEN: Tuesday, December 28, 5:30am to 7:30am.
DETAILS: We will be performing maintenance on our two file servers, rtfm and barley, that will require downtime for both those systems and several other major CS IT services as well. The affected IT services will be unavailable on Tuesday, December 28, from 5:30am to 7:30am. 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, but since CS Ugrads can send through the JHU mail server, CS Ugrads might still be able to send email during the outage.
    • 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) will remain available, but, if you have a personal or lab page that we maintain locally in the dept, those will be unavailable. The CS IT Support Wiki and its Notices page will remain available.
  • Grad/Research Net and Ugrad Net user accounts and home directories will be inaccessible during the outage.
  • 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.
  • Console (desktop) access at any of our lab 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 and the dbase.cs.jhu.edu server will be unavailable.
We will update this Notices page if there are changes or any delay in the restore time of our IT services.
