PLANNED CS IT SERVICE OUTAGES

Major Malone Power Outage Planned (Affecting CS IT Services) - Friday, Aug 11, 2023 from 12am to 1am (CS IT Services Outage before and after Power Outage as well)

WHAT: There will be no CS IT computing services available during an upcoming major power outage for ALL of Malone Hall.

WHEN: Power Outage - Friday, August 11, 2023, starting at 12am (midnight) and running until sometime around 1am (so, roughly, an hour.)

Loss of CS IT services - Thursday, August 10, 2023, starting at 11pm (one hour before the power outage) and lasting until Friday, August 11, sometime around 3am (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 12am, 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 11pm the evening of Thursday, August 10. And although the power to the building should restored around 1am Friday morning, we will not have all our systems back up and running until approx. 3am, so plan on about 2 hours after the power outage is deemed over until our servers and services are 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.

Tracking Our CS IT Services Status Updates During The Outage

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

(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 this Notices page available again.

CS IT Services Unavailable During The Power Outage Include...

• 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. 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.

• 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.

• 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.

• Wifi access points in Malone Hall will be without power and will therefore not be available.
