Planned JHU Service Outages TEMPLATES

Template JHU Service Outage 1

Planned JHU outage with Malone Hall

  • WHEN: Friday, March 10, starting around 11am and lasting until completed
  • WHAT: 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.

    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.

Template JHU Service Outage 2

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.
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.
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.

Planned JHU Outage 3. BGE Outage

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.
In the case of the upcoming 6/26 testing, there is a potential for another short power outage (1 to 2 minutes) that evening.
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.
Once the power returns, our services should be available again, because the network should be available again.
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.
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.
For your own equipment, whether it be in your office or the server room, please prepare as for any other planned power outage.
If there are additional details that we hear of, we will update here.


UNPLANNED JHU SERVICE OUTAGES TEMPLATES

9/29/23 MAJOR JHU email outage and delays

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.)
UPDATE: JHU has implemented a work-around to the email problem, and email delivery has returned to normal.

Phishing TEMPLATE

PHISHING EMAIL AND OTHER ACCOUNT ISSUES!

5/5/20: We are currently receiving a large number of phishing emails directed at the CS Department. If you receive an email with links in it and have any doubts about the email, do not click the link. You do not need to send the emails to us at this time, as we are actively tracking the situation.
Also...
Because of these phishing attacks, if you've followed the phishing links and provided your account credentials to others, and then find you are unable to login to your CS account get your CS email, then, please see our password reset procedures. If your CS email account has been disabled, and you need you need to contact us, you will need an alternate non-CS email address to do so. Also, if you did follow a phishing link and enter your account credentials and then realize what happened, please email support@cs.jhu.edu right away, and let us know.

PLANNED CS IT SERVICE OUTAGES - TEMPLATES

TEMPLATE - MAJOR OUTAGE RTFM

OUTAGE: MAJOR CS IT SERVICES OUTAGE

WHAT: Most CS IT Grad Net services will be unavailable due to file server maintenance.

WHEN: Thursday, August 15, 4am to 7am.

DETAILS: We will be performing upgrade maintenance on our servers, including the department's main file server (named "rtfm") that services the Grad Net (affecting all Faculty, staff, instructors, and CS grad students), and will require downtime for several major CS IT services. The affected IT services will be unavailable on Thursday morning, August 15, from 4am to 7am. 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. 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 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 services outage (just not one of our lab computers or compute servers.)
  • 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) may or may not remain accessible. If you have a personal or lab CS page that we maintain locally in the dept, those will be unavailable. The CS IT Support Wiki and its Notices page will remain available.
  • The CS staff documentation website will be unavailable.
  • All CS Linux user accounts and home directories will be inaccessible during the service outage.
  • ssh service to our Linux clients (masters1 through masters16, ugrad1 through ugrad24, gradx, ugradx, gradz, and ugradz) will be unavailable.
  • Console (desktop) access at any of our Masters 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 will be unavailable.
