CS IT STAFF AVAILABILITY

  • The CS IT Support staff operates out of 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 are 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.
  • 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

CS Lab Computers Unavailable and Labs To Be Closed Due To ACM Contest Event

WHAT: The 1st floor CS Ugrad Lab, MH-122, and the 3rd floor CS Masters/MSSI Lab, MH 316/322 will be closed due to an upcoming ACM Programming Contest. Additionally ALL of our Linux computers that are located in the CS labs (masters1 through masters4 & ugrad1 through ugrad12) will also be unavailable as well during that time due to the ACM Programming Contest.
WHEN:
CS Masters & Ugrad lab Linux systems unavailable starting 5pm, Friday, November 6 and lasting through 9pm on Saturday, November 7.
CS Computing Labs physically unavailable starting 6am Saturday, November 7 through 11pm that same evening.
DETAILS
Although these labs will be closed and the lab computers will be unavailable, you may still remotely access (via ssh) our Grad and Ugrad Linux compute servers that include:
gradv.cs.jhu.edu
gradx.cs.jhu.edu
gradz.cs.jhu.edu
ugradv.cs.jhu.edu
ugradx.cs.jhu.edu
ugradz.cs.jhu.edu
For a list of our various systems (including our remotely available gradv, gradx, gradz, ugradv, ugradx, & ugradz Linux systems), please see:
Linux_Clients_on_the_CS_Undergrad_Net
or
Linux_Clients_on_the_CS_Grad/Research_Net
We have to take down the lab systems late that Friday afternoon. At the end of the ACM contest that Saturday night, the coordinators of the contest will be turning our lab computer systems back on. Most should boot normally. But, if some do not, just trying using an alternate one in the lab. (And remember, our compute servers, referenced above, will continue to be available remotely.) We'll be back onsite the Monday afterwards and can check on any systems that didn't boot normally.
NOTE: The printers in MH 122 and MH 316/322 will remain online, but, please pick up your printouts outside of the contest hours.



CS COMPUTING LAB AVAILABILITY

MH 122 (CS Undergrad Lab/Collaboration room) will be closed November 7, 2026. Please see the earlier entry on the planned CS lab computer outage for timing details.


MH 316/322 (CS Masters Lab & MSSI Lab) will be closed November 7, 2026. Please see the earlier entry on the planned CS lab computer outage for timing details.
