  |details=JHU Networking will be swapping out all of the Hopkins-managed Malone Hall ''wifi'' access points in the building. 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:''' Thursday, October 3, starting at 10:30pm and lasting to approximately midnight.
+
::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:''' JHU is updating the software on all the Malone Hall closet network switches this coming Thursday evening. Each switch might take up to 10 minutes to reboot. The whole process might take an hour and a half, but you're likely to only notice a few minute outage, depending upon what wallport your system is connected to or what wifi access point you're connected to.
+
::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.
  
−
::So, if you're in a Malone Hall office or lab, and your system is connected to a wallport (or to a local switch connected to a wallport), you will probably notice up to 10 minutes of no network connection at some point sometime between 10:30 and midnight.  You might experience the same loss of network connectivity  with any connections to wifi in Malone Hall.
+
::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.
−

:: G29 server room users: We're told that the G29 server room itself will not have its network switch affected, however, connections to and from G29 might be affected the building network switch its connected to is rebooted.

::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.

=== UNPLANNED CS SERVICE OUTAGES ===
+
::In the case of the upcoming 6/26 testing, there is a potential for another short power outage (1 to 2 minutes) that evening. 
  
−
WHAT:  Issues with the CS Ugrad Mail and Web service.
+
::A short outage of this type will affect our CS servers and IT services in the following way:  Although our servers should physically stay running, as they are on battery-backed equipment, because our services require network connections that are controlled by JHU (and not on battery backup), all of our CS IT services will be unavailable during the expected brief outage.
  
−
WHEN: 3/31/20 Starting around 9:30am
+
::Once the power returns, our services should be available again, because the network should be available again.
  
−
DETAILS:
+
::Also, if there is indeed an outage, the CS Grad and Undergrad Lab systems (that currently, you can only access remotely) will power off.  However, when power is restored, those lab systems should automatically reboot.
  
−
The server that provides our CS Ugrad Mail and Web service is having issues connections from outside of JHU (which we're looking into.) However, if you're on the [https://support.cs.jhu.edu/wiki/VPN_-_JHU JHU VPN] or on the JHU Network, you can still access these services.
+
::Other notes:  WiFi and other networking in the building would be unavailable during the outage.  Most likely, lights would be unavailable.   My group does not maintain J-Card systems, so we do not know how the J-Card readers will perform during a power outage.
  
−
Affected services include:
+
::''For your own equipment, whether it be in your office or the server room, please prepare as for any other planned power outage.''
  
−
* Ugrad web pages; these are not accessible unless you're on the JHU network or VPN.
+
::If there are additional details that we hear of, we will update here.
−
 
 
−
* CS Ugrad email accounts; mail clients cannot check ugrad mail unless they're on the JHU network or VPN.
 
−
 
 
−
Inbound CS Ugrad email should work without issues.

::As you know, recently, we upgraded our lab Linux clients to Fedora 31.  Over the past several days, we've discovered some odd behavior from some of the lab systems.  Upon further investigation, we have learned that there is a kernel bug that is causing some systems to hang (requiring a reboot) when certain NFS operations are performed.  (NFS is the system that allows our Linux clients to access the home directories, certain apps, other shared file systems.)
+
=====Tracking Our CS IT Services Status Updates During The Outage=====
  
−
::We're seeing that the bug is documented and that it affects not only Fedora 31, but some prior versions as well.  It just happens to be that we are seeing its effects now.
+
: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):
  
−
::This is a Linux kernel issue and there are Linux folk working on trying to get this bug patched, but we do not know how long it will take.
+
::[https://csstatus.jhu.edu https://csstatus.jhu.edu]  We will update that page soon with this information.
  
−
::In the meantime, CS IT is looking into work-arounds to bypass this bug as much as possible.
+
:(Bookmark that link ahead of time, in case you can't access your CS mail during the outage.)
  
−
::There is no way to predict if or when this bug will cause a system to hang.  Some of our systems may never notice it.  We think it might happen to some systems that are heavily utilizing NFS operations, but again, we're not sure.
+
:As soon as we're able to do so after the outage, we'll also make this Notices page available again.
  
−
::Our recommendation is that when you're editing files, etc. save your work on a regular basis, just in case. This is a good practice to follow anyway.
+
=====CS IT Services ''Un''available During The Power Outage Include...=====
  
−
::'''''IMPORTANT:'''''  If you experience a system that hangs (and doesn't recover after several minutes), please email  {{mailto|support}} to let us know the name of the system that experienced the hang, the time of the hang, and what activity you were doing on the system at that time (which will help us troubleshoot the problem further.)
+
* 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 will update here with our progress on circumventing this bug.
 
  
−
::'''UPDATE:  1/29/20'''  We are applying alternative pre-bug kernels to those  Linux clients that are available to be rebooted (to activate these kernels.) As more become available, we'll reboot them as well.  We're hoping these alternative kernels will prevent the hangups until officially patched kernels become available.
+
* 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 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.
  
−
::'''UPDATE:  2/7/20'''  We have applied updates to most of our systems in order to activate the alternative pre-bug kernels, which we hope will prevent hangups.  There are still some systems which have not yet had the alternative kernels applied, and that will happen as the systems become available for us to reboot.
+
* '''No''' CS webpages will be available. This includes the main CS website.  And, as mentioned above... because we will not have power 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.
