They plan to start work around 11am that Friday, and they expect it could take 4 hours, more or less, to replace them all.  During that time, wifi access might disappear and reappear.  Additionally, when your wireless device tries to reconnect to the newly-replaced access point, you ''might'' be prompted to accept a certificate, and we were informed that you should do so.<br/>

::JHU Networking has indicated they are testing power transfer equipment in Mason Hall that will affect several buildings, including Malone and Hackerman.  They will be cycling power to the buildings, perhaps several times.  They expect their outages to be < 10 seconds each.
  
−
::'''WHEN:''' Saturday, June 26, starting at 8pm
+
::Our CS IT servers that provide you most of our IT services should remain up and running, since our servers have backup battery power.  Unfortunately, the JHU network in the building does not.  So, you will probably experience brief network interruptions when the power is cycled by Facilities.  And each time the power is out, CS services that you interact with (email, web, home directories, etc.) will be inaccessible due to the building's network being unavailable during the outage times.
  
−
::'''DETAILS:'''
+
::Faculty who run their own servers in the CS Server Room (MH G-29), please note that if you do not have UPS units in your racks (and most of you do not), you can expect your systems will power cycle each time Facilities cycles power in Malone Hall.  Please be aware.  PhD students who maintain those systems (and perhaps other systems in the building), please keep that in mind as well.
  
 +
::The CS computing labs' systems (currently, for the summer, all located in G-61), those computers are not on UPS systems, so those computers will power cycle and should boot back up on their own.  But, if you're planning to use our lab systems, because they might go up and down several times during the electrical work time period, you might not want to do your school work on those systems during that time.

::JHU Facilities is preparing for BGE to test electrical equipment that affects several Homewood buildings.  They will be performing this test on Saturday evening, June 26 at 8pm.  If you recall, back on May 6, there was a very short power outage that affected our building and others.  The testing BGE will be doing is part of their troubleshooting what happened in May.

:JHU is experiencing email issues with it's @jhu.edu mail services due to a global outage at Cisco.  This affects both incoming and outgoing email messages to external recipients.  It also impacts systems that send email through JHU's email gateways.  Expect major mail delays until this is fixed.  (We suspect that those with @jhu.edu addresses can still send and receive to others with @jhu.edu addresses.)

−
:'''WHEN:'''  ''Wednesday, November 17, 5:30am to 7am.''
+
:'''WHEN:'''  Power Outage - Saturday, March 30, 2024, starting at '''6am''' and running until '''2:30pm''' (so, roughly, 8.5 hours.)
  
−
:'''DETAILS:''' As we are switching our mail server software to a different "brand" of software, during the transition time, several of our CS mail services will be unavailable during this time period.
+
:: Loss of CS IT services - Saturday, March 30, 2024, starting at '''5am''' (one hour before the power outage) and lasting until '''4:30pm''' (two hours after the power outage is completed.)

=====CS Mail Services That Will '''''Not''''' Be Available=====
+
:'''DESCRIPTION:'''   JHU is planning an a all-day power outage for Malone Hall, and all of our computing services will be unavailable during that time.
  
−
* Inbound mail. Mail that people send to @cs.jhu.edu email addresses will not be accepted during this time period.  The sending mail server    should hold on to the messages and resend them after service has been restored.  Any mail sent to @cs.jhu.edu email addresses during the   maintenance should arrive, just delayed by some period of time.
+
:The actual power outage is planned to start at 6am, Saturday morning, March 30,, and will continue for approximately an 8.5 hours.  '''''However,''''' we need to safely bring down our computer servers and clients ''earlier'' than that (before the power goes out.) We plan to bring our systems down that morning around '''5am'''. And although the power to the building should restored around 2:30pm that same day, we will not have all our systems back up and running until approx. 4:30pm, so plan on about 2 hours after the power outage is deemed over until our servers and services are available again.
  
−
* Outbound mail.  People with CS grad mail accounts will not be able to send mail during the maintenance.  Please wait until after 7:00 am to    send mail with your CS account.  Note: People with *ugrad* accounts will still be able to send mail, since they use JHU's mail server for sending mail.
+
:<span style="color:#ff0000">Please read all of the notes below regarding Malone Hall Residents, CS Server Room users, and a list of the CS IT services that will be unavailable during the outage. </span>
  
−
* CS Mailing Lists.  During the mail service switchover, CS mailing lists will be unavailable.
+
::<span style="color:#ff0000">'''NOTES TO MALONE HALL RESIDENTS:'''</span>  During the time of the outage, we're assuming most building lights will be out and the J-Card system might be out too.  That might make it more difficult to get into the building during the outage.  But with the power out, we're not sure how much need there will be for anyone to be in the building during that time anyway.  If you have an office refrigerator, expect that to be out too.  If you are counting on your UPS (battery-backup) systems to continue powering your office equipment, keep in mind the expected length of the outage (8 hours) and plan for a longer period of time, just to be safe.  And keep in mind that your office phones may be inoperable during the outage.  So please plan in advance for this outage.  
  
−
=====CS Mail Services That Will Remain Available=====
+
::<span style="color:#ff0000">'''NOTE TO CS SERVER ROOM (MH G-29) SERVER OWNERS:''' </span>  Our server room will be out of power, so our servers will be unavailable.  If you host servers in the server room, your servers will be down as well.  Plan ahead of time to shut down and to bring back up your servers.  Your group is responsible for any systems you choose to shut down before the outage or boot back up after the outage.
  
−
* IMAP and POP.  If you use a mail client to access your CS mail remotely, this will continue to work.  You will still be able to read messages already in your mail mail folders (though, as noted above, no new messages will de delivered).  The CS webmail uses IMAP, so you  will be able to access your existing messages from webmail.
+
=====Tracking Our CS IT Services Status Updates During The Outage=====
  
−
* Mail spool access from the Linux clients.  If you use a direct-access  mail client on the CS Linux clients (e.g. pine), you will continue to    have access to all of your email messages (though, as noted above, no new messages will de delivered).
+
:Because we will not have power 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):
  
 +
::[https://csstatus.jhu.edu https://csstatus.jhu.edu]  We will update that page soon with this information.

:The actual power outage is now planned to start at 4pm, Saturday afternoon, October 23, and will continue overnight until Sunday morning, October 24 at 4am.  However, we need to safely bring down our computer servers and clients earlier than that (before the power goes out.) We plan to bring our systems down around '''3pm''' that Saturday afternoon. And although the power should be up around 4am Sunday morning, we will not have all our systems back up and running until approx. 6am, so plan on about 2 hours after the power outage is deemed over until our servers and services are available again.
+
:* On Wednesday, February 2, the Linux clients ugradx and gradx will be upgraded.  Please use ugradz/gradz or the lab client systems (ugrad1-24/masters1-16) instead.
 +
:** As of 2:00 pm, both ugradx and gradx have been upgraded.
  
 +
:'''NOTE:'''  On each day, the upgrades will start at roughly 9:00 am and are expected to be complete by 5:00 pm.

==== Major CS Grad/Research Net and Ugrad Net IT Services Outage====
  
−
:<span style="color:#ff0000">Please read all of the notes below regarding Malone Hall Residents, CS Server Room users, and a list of the CS IT services that will be unavailable during the outage. </span>
 
  
−
::<span style="color:#ff0000">'''NOTES TO MALONE HALL RESIDENTS:'''</span>  During the time of the outage, we're assuming most building lights will be out and the J-Card system might be out too.  That might make it more difficult to get into the building during the outage.  But with the power out, we're not sure how much need there will be for anyone to be in the building during that time anyway.  If you have an office refrigerator, expect that to be out too.  If you are counting on your UPS (battery-backup) systems to continue powering your office equipment, please realize that this is an expected over-12-hour outage.  And keep in mind that your office phones may be inoperable during the outage.  So please plan in advance for this outage.  
+
:'''WHAT:''' Most CS IT services will be ''un''available due to file server maintenance.
  
−
::<span style="color:#ff0000">'''NOTE TO CS SERVER ROOM (MH G-29) SERVER OWNERS:''' </span> Our server room will be out of power, so our servers will be unavailable.  If you host servers in the server room, your servers will be down as well.  Plan ahead of time to shut down and to bring back up your servers.  Your group is responsible for any systems you choose to shut down before the outage or boot back up after the outage.
+
:'''WHEN:'''  ''Tuesday, December 28, 5:30am to 7:30am.''
  
−
====Tracking Our CS IT Services Status Updates During The Outage====
+
:'''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.
