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.

PLANNED CS IT SERVICE OUTAGES

OUTAGE #1: MAJOR CS IT SERVICES OUTAGE

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

WHEN: Thursday, August 15, 4am to 7am.

DETAILS: We will be performing upgrade maintenance on our servers, including the department's main file server (named "rtfm") that services the Grad Net (affecting all Faculty, staff, instructors, and CS grad students), and will require downtime for several major CS IT services. The affected IT services will be unavailable on Thursday morning, August 15, from 4am to 7am. 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. 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 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 one of 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.
  • Grad/Research Net Linux user accounts and home directories will be inaccessible during the service outage.
  • ssh service to our CS Grad/Research Net (masters1 through masters16, gradx, and gradz) will be unavailable.
  • Console (desktop) access at any of our Masters 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 will be unavailable.

OUTAGE #2: CS Linux Lab Systems Downtime/Upgrade Schedule

WHEN: Tuesday, August 19 through Friday, August 23 WHAT: Subsets of the CS Linux clients will be down for upgrades over the course of the week. DETAILS: In prepping for the new semester, we will be upgrading the CS Dept's Linux clients (our lab systems and others that are remotely-accessible-only) from Fedora 38 to Fedora 40. This will require having the clients offline during the upgrades. We'll do this in stages, so there will always be some clients available at all times.

The upgrade schedule for these systems will be as follows:

  • On Monday, August 19, ugrad1 through ugrad12 (in MH 122) will be upgraded.
  • On Tuesday, August 20, ugrad13 through ugrad24 and masters1 through
       masters16 (in MH G61) will be upgraded.
  • On Wednesday, August 21, ugradz and gradz (remotely-accessible only) will be upgraded.
  • On Thursday, August 22, ugradx and gradx (remotely-accessible only)
       will be upgraded.
  • On Friday. August 23, any systems that had to be skipped during the
       previous days will be upgraded. Our Notices page will have information
       about any such systems.
