::'''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.

  |summary=Wi-Fi access point replacement
 +
  |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/>

After the wifi outage, if you continue to have issues with your device, '''''please contact JHU IT directly...''''' Visit [[Wireless Networking]] for details on who to contact for assistance.

::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.
  
−
::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.
+
::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.
  
−
:: 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.  
+
::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.
  
−
:None at this time.
+
::In the case of the upcoming 6/26 testing, there is a potential for another short power outage (1 to 2 minutes) that evening.
  
−
<br>
+
::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.
  
−
=== PLANNED CS SERVICE OUTAGES ===
+
::Once the power returns, our services should be available again, because the network should be available again.
  
−
:None at this time.
+
::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.

:'''WHAT:''' Linux kernel bug causing some of our Fedora 31 lab systems to hang.

::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.)
+
== <span style="color:#ff0000">CS IT SERVICE OUTAGES (Unplanned & Planned)<span>==
  
−
::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.

::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.

====<span style="color:#ff0000">9/29/23 MAJOR JHU email outage and delays</span>====
  
−
::In the meantime, CS IT is looking into work-arounds to bypass this bug as much as possible.
+
: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.)
  
−
::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.
+
:'''''UPDATE:'''''  JHU has implemented a work-around to the email problem, and email delivery has returned to normal.

::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.

<!-- <br>-->

::'''''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.)

::'''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.
 
  
−
::'''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.

:'''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.
  
 +
: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.

::<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.
