[10:42 am, Aug 10] Update - The power outage has been cancelled. No new date has been set, nor do we even know if BGE is planning to reschedule the outage.
WHAT:
There will be no CS IT computing services available during an upcoming major power outage for ALL of Malone Hall.
WHEN:
The power outage will start at 12:00 am on Friday, August 11, 2023 and will last until sometime around 1:00 am; roughly an hour.
CS IT services will start to be shut down at 11:00 pm on Thursday, August 10, 2023, one hour before the power outage. Services should by fully restored by 3:00 am, two hours after the power outage is completed.
DESCRIPTION:
JHU is planning an a 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 12:00 am, early Friday morning, August 11, and will continue for approximately an hour. 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 11:00 pm the evening of Thursday, August 10. Although the power to the building should restored around 1:00 am Friday morning, we will need some time to restart all of our services and verify their functionality. We expect to have all our systems back up and running by 3:00 am, so plan on a window of about two hours after the power outage is over for our servers and services to be available again.
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.
NOTES TO MALONE HALL RESIDENTS: 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 (an hour) 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.
NOTE TO CS SERVER ROOM (MH G-29) SERVER OWNERS: 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.
Because we will not have power to our servers in Malone Hall, the CS IT Support website, and especially the Notices page 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):
(Bookmark that link ahead of time, in case you can’t access your CS mail during the outage.)
As soon as we’re able to do so after the outage, we’ll also make the Notices page available again.
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.
CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users. In addition, 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.
All CS webpages will be unavailable. This includes the main CS website, the CS IT Support Wiki, and a number of others. Since the IT Support Wiki’s Notices page will be unavailable during the outage, please refer to https://csstatus.jhu.edu for status updates during the outage.
Grad/Research Net and Ugrad Net user accounts and home directories will be inaccessible during the power outage.
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.
Console (desktop) access at any of our 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 and through the dbase.cs.jhu.edu server will be unavailable.
Network switches in the building will be without power, so no network connections in Malone Hall will work.
Wifi access points in Malone Hall will be without power and will therefore not be available.
