JHU IT SERVICE OUTAGES AFFECTING CS IT SERVICES

PLANNED JHU SERVICE OUTAGES

JHU OUTAGE 1 AFFECTING CS:

WHAT: 5 to 15-minute network outage in Malone Hall
WHEN: Thursday, December 23, sometime between 4am and 6am.
DETAILS:
JHU Networking has indicated they will be upgrading the OS on almost all their network distribution routers on Dec 23rd from 4am to 6am. There will be a short (5 to 15-minute) disruption during the reboots of these routers, including the one for Malone Hall. This will affect both wired and wireless services at Malone Hall.

JHU OUTAGE 2 AFFECTING CS:

WHAT: Several brief network outages in Malone Hall lasting from 5 to 15 minutes.
WHEN: Tuesday, December 28, sometime between 4am and 5am.
DETAILS:
JHU Networking has indicated they will be upgrading the OS on a different piece of network equipment than the one they're performing on 12/23. And upgrading that additional piece of network equipment will cause some brief network outages the morning of 12/28 from 4am to 5am affecting both wired and wireless networking in Malone Hall. This is the same morning that, later on, we will be doing our server maintenance (see another post on this Notices page for details on that.)

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.


PLANNED CS IT SERVICE OUTAGES

Major CS Grad/Research Net and Ugrad Net IT Services Outage

WHAT: Most CS IT services will be unavailable due to file server maintenance.
WHEN: Tuesday, December 28, 5:30am to 7:30am.
DETAILS: We will be performing maintenance on our two file servers, rtfm and barley, that will require downtime for both those systems and several other major CS IT services as well. The affected IT services will be unavailable on Tuesday, December 28, from 5:30am to 7:30am. 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. 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 outage.
    • 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) will remain available, but, if you have a personal or lab 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 and Ugrad Net user accounts and home directories will be inaccessible during the outage.
  • ssh service to our CS Grad/Research Net & Ugrad Net Linux boxes (masters1 through masters16, ugrad1 through ugrad24, gradx, gradz, ugradx, and ugradz) will be unavailable.
  • Console (desktop) access at any of our 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 and the dbase.cs.jhu.edu server will be unavailable.
We will update this Notices page if there are changes or any delay in the restore time of our IT services.
