=====Tracking Our CS IT Services Status Updates During The JHU-Planned Malone Network Outage=====
+
==== CS Labs/Systems Will Be Unavailable ====
 +
:'''WHAT:''' Malone Hall MH 122 '''and''' Malone Hall G61, both the Masters and Ugrad sides of the lab, and ''all'' the lab Linux computers, will be closed to CS students due to an ACM Programming Contest.
  
−
:Because we will not have network access to our servers in Malone Hall, the CS IT Support Wiki, and especially this Notices page ( https://support.cs.jhu.edu/wiki/Notices ) will be unavailable during the outage.  Instead, during the outage, we have arranged for status updates to be available at the following website (served at an off-site facility):
+
:'''WHEN:'''  Starting Friday evening, November 7, 5pm '''through''' Saturday, November 8, 9pm.
  
−
::[https://csstatus.jhu.edu https://csstatus.jhu.edu]  We will update that page soon with this information.
+
:'''DETAILS:'''
  
−
:(Bookmark that link ahead of time, in case you can't access your CS mail during the outage.)
+
: Both the MH 122 '''and''' G61 Masters and Ugrad Labs will be used for an ACM Programming Contest and will therefore be '''''closed''''' to those not participating in the contest.
  
−
:As soon as we're able to do so after the Network outage, we'll also make this Notices page available again.
+
: Additionally, all of the labs' Linux computers (masters1 through masters16 and ugrad1 through ugrad24) will be unavailable during the time period referenced above.
  
−
=====CS IT Services ''Un''available During The JHU-Planned Network Outage Include...=====
+
* During the lab closure times, compute servers, gradx.cs.jhu.edu, gradz.cs.jhu.edu, ugradx.cs.jhu.ed, and ugradz.cs.jhu.edu  '''''will continue to be available remotely''''', via SSH.
  
−
* DNS resolution (hostname lookups) for all cs.jhu.edu hostnames will be unavailable.  This will affect all websites with cs.jhu.edu domain names, even if the website is hosted by someone other than the CS department.
+
* 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 that 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. We'll be back in the Monday afterwards and can check on any systems that didn't boot normally. (And don't forget, as mentioned above our compute servers -- gradx, gradz, ugradx, ugradz -- will continue to be remotely available, even if the lab systems are not.)
  
−
* 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.
+
* The printers in MH 122 and MH G61 will remain online, but, please pick up your printouts outside of the contest hours.
−
** Incoming mail ''should'' be queued by the sender until our mail service is back up again. Outgoing mail will not be available.
+
-->
−
** 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 (just not from a Malone Hall–based computer.)
+
<!--
−
** IMAP, POP, and webmail (for both Grad/Research and Ugrad accounts) will be unavailable.
+
==== Scheduled Networking Outage on the Malone Ground Floor ====
  
−
* '''No''' CS webpages will be available.  This includes the main CS website.  And if you host a website with ''.cs.jhu.edu'' in its hostname, it too, will be unavailable.  And, as mentioned above... because we will not have networking access to our servers, the CS IT Support Wiki, and especially its Notices page will be unavailable during the outage.  Please refer to https://csstatus.jhu.edu for status updates during the outage.
+
:'''WHAT:''' WiFi and Ethernet connections will not be available on the ground floor of Malone Hall during an upcoming JHU-planned networking outage.
  
−
* Grad/Research Net and Ugrad Net user accounts and home directories will be inaccessible during the network outage.
+
:'''WHEN:'''  JHU's Planned Network Outage – Wednesday, August 27, 2025, from 8pm through midnight.
  
−
* 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.
+
:'''DESCRIPTION:''' JHU is planning a network outage at Malone Hall to install new networking equipment.  The outage will start at 8:00 pm and is expected to last between two and four hours.  During the outage, the wireless access points on the ground floor will be offline, as will most of the Ethernet jacks.  Please be prepared to not have any network connectivity on the Malone ground floor during this time.
  
−
* Console (desktop) access at any of our lab Linux client systems will be unavailable.
+
:Ethernet connections in the Malone server room, G29, will not be affected by this outage. Any servers in G29 should remain accessible. The Linux clients and Ethernet jacks in room G61, which contains the ground floor masters and undergrad labs, will not be affected either. (But any laptops brought into G61 during the outage probably won't be able to access the wireless network.)
−
 
+
-->
−
* 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 through the dbase.cs.jhu.edu server will be unavailable.
 
−
 
 
−
* Since this is a JHU-planned network outage, there will be no network connections in Malone Hall.

==== Outage of Linux Lab Systems During Upgrades====
 
−
'''WHEN:''' Tuesday, August 19 through Friday, August 22
 
−
 
 
−
'''WHAT: '''Subsets of the CS Linux clients will be down for upgrades over the course of the week.
 
−
 
 
−
'''UPDATE:''' As of about 12:30 on Tuesday, all ugrad systems from ugrad1 through ugrad12 have been upgraded.
 
−
 
 
−
'''DETAILS:''' We will be upgrading our Linux clients from Fedora 40 to Fedora 42. 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 lab machines whose numbers are integer multiples of five (ugrad5, ugrad10, ugrad15, ugrad20, masters5, masters10, and masters15) have already been upgraded (those are the staging systems we mentioned in a recent email to the CS faculty and students), so those will remain available throughout the week. The upgrade schedule for the remainder of the systems will be as follows:
 
−
 
 
−
*    On Tuesday, August 19, ugrad1 through ugrad12 (located in MH-122) will be upgraded (...except for ugrad5 and ugrad10, which are already done.)
 
−
*  On Wednesday, August 20, ugrad13 through ugrad24 and masters1 through masters16 (located in MH-G61) will be upgraded (...except for ugrad15, ugrad20, masters5, masters10, and masters15, which are already done.)
 
−
*  On Thursday, August 21, ugradx and gradx (remotely-accessible only) will be upgraded.
 
−
* On Friday, August 22, ugradz and gradz (remotely-accessible only) will be upgraded, along with any systems we were unable to upgrade earlier in the week.
 
−
 
 
−
Expect each system being upgraded to be unavailable between 9:00 am and 4:00 pm on the days for which it's scheduled. If a system remains unavailable after 4:00 pm on its scheduled day, this CS IT Support Wiki's Notices page will be updated with the appropriate information.
