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.

JHU IT SERVICE OUTAGES AFFECTING CS IT SERVICES

PLANNED JHU SERVICE OUTAGES

JHU Planned Sporadic Network Outages, 6/28/25 from 9am to 4pm

On Saturday June 28th starting at 9am and continuing until 4pm, the University Networking team will be replacing the existing campus core with two new Arista 7508’s. This upgrade is being done because the current core devices are very close to end-of-life and will not meet the needs of the campus into the future. The new platform will allow for greater bandwidth going forward. The first upgrade, which is part of this change, will increase the uplinks to the Enterprise network from 4x10gig connections to 4x25gig connections. Along with the upgrade to the Enterprise Network, University Networking will move all buildings that connect to the current Homewood campus core to the new campus core. This process will require sporadic but brief outages of up to 3 minutes throughout the change window. We are not anticipating any long outages, just the brief outages while we move fiber connections from one core to the other.

PLANNED CS IT SERVICE OUTAGES

**OUTAGE: MAJOR GRAD/RESEARCH NET CS IT SERVICES OUTAGE**

WHAT: Major CS Grad/Research Net IT services outage, as we configure networking changes on our Grad/Research Net file server...

WHEN: Tuesday, June 24, 2025 from 5am to 7am.

DETAILS: We are performing network configuration changes on our Grad/Research Net's home directory file server known as "rtfm.cs.jhu.edu".

This will take approximately 2 hours to complete. During this time, several our of Grad/Research Net IT services will be unavailable. Below is a list of the services affected...

CS IT Services That Will Not Be Available During The Service Outage:

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/Research 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.

All CS Linux user accounts and home directories will be inaccessible during the service outage.

ssh service to our Linux clients (masters1 through masters16, ugrad1 through ugrad24, gradx, ugradx, gradz, and ugradz) will be unavailable.

Console (desktop) access at any of our Lab Linux client systems (Grad/Ugrad) 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.

Updates will be displayed on this page.
