PLANNED CS SERVICE OUTAGES

WHAT: Major CS Grad/Research Net (and some Ugrad) IT services outage, as we update our file server system.

WHEN: Wednesday, June 13, from 5:30pm to approx 7:30pm.

DETAILS: Our CS Grad/Research Net home directory file server-related system, rtfm.cs.jhu.edu, will be shut down so that important server-related updates can be applied. (In order to shut down that server, we must also shut down our mail, DNS, and other services server, blaze.cs.jhu.edu.) We will apply the required updates on Wednesday, June 13, from 5:30pm to approximately 7:30pm.

During the process of applying updates, several of our CS services will be unavailable. If there are any unexpected complications during the update process that will delay the restoration of services, we will update this CS IT Support Wiki's Notices page.

Suspended (Unavailable) Grad/Research Net services while rtfm.cs.jhu.edu & blaze.cs.jhu.edu are down:

• CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users.

• Incoming mail should be queued by the sender until our mail service is back up again. Outgoing mail will not be available.

• IMAP, POP, and Webmail from our CS (Grad/Research Net) Mail server will be unavailable.

• Some CS webpages, including user (and possibly lab and other CS pages), will be unavailable.

• Grad/Research Net user accounts/home directories will be inaccessible during the downtime.

• SMB File Shares (CS Office Staff uses these) will be unavailable.

• ssh service to our CS Grad/Research Net Linux boxes (masters1 through masters16, gradx, and gradz) will be unavailable.

• Console (desktop) access to masters1 through masters16 will be unavailable.

• MySQL service via the mysql.cs.jhu.edu server will be unavailable.

Note to Ugrad Net users: During the rtfm.cs.jhu.edu and blaze.cs.jhu.edu updates, email directed to your ugrad acct @cs.jhu.edu will not be immediately delivered. Other Ugrad Net services should remain available.

CS COMPUTING LAB AVAILABILITY

MH 122 (Ugrad Lab/Collaboration Room) Will Be Closed For The Summer

WHEN: Fri., May 25 through Thu., Aug 9

DETAILS: Maintenance work and a CSLP Summer Workshop will be happening in this room during this time. In addition to the main MH-122 room, its three breakout rooms and the MH-122 printer will all be unavailable as well.

MH-122 will reopen on Friday, Aug 10.

NOTES:

• The G-61 Masters/Ugrad Lab will remain open and available during the summer. The G-61 printer will remain available as well.

• The MH-122 Linux systems, ugrad1 through ugrad12, will continue to be available, but only remotely via ssh. (There will be some downtime for those systems on 5/25 and 8/9 as the systems are transferred from, and then, back to MH-122.) Please see: https://support.cs.jhu.edu/wiki/Linux_Clients_on_the_CS_Undergrad_Net for a list of our remotely-available Ugrad Linux systems.

Projector in the main MH 122 Ugrad lab is down.

11/2/17 - Kit-cats (JHU's A/V group) has been called. They have been out and are evaluating their options for repair. ETA for repair is unknown at this time.

MH G-61 (Masters/Ugrad Lab)

WHEN: July 1, 2018 through August 24.

WHAT: Lab availability changes for Summer, 2018.

DETAILS: From July 1, 2018 through August 24, 2018, the Masters Lab side of this room (G-61) will be closed to CS students, as its desks are being assigned to specific visiting students. However, the Ugrad Lab (inner room) section of G-61 will be available to both Ugrad and Masters students during that time. So, you can come through this room's main entrance and head directly to the CS Ugrad lab side. The Ugrad Lab has the Ugrad Net's Linux clients (ugrad13 through ugrad 24.)

CS Masters students needing access to the Grad Net Linux systems can log into the Ugrad desktops first, and then ssh into the desired Grad Net Linux systems.

During this period of time, the G-61 printer has been temporarily located from the Masters side to the back of the Ugrad side.

(Please do not touch the computers stacked at the back wall of G-61's Ugrad Lab. Please leave them powered on.)
