CS IT STAFF AVAILABILITY

Beginning Fall semester, 2021,...
  • The CS IT Support staff will be back in Malone Hall. Our group will be working a hybrid schedule with some of us working remotely on certain days, while others of our team will be on campus.
  • We will 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.
