PLANNED CS SERVICE OUTAGES

WHAT: No CS IT computing services due to major power outage for ALL of Malone Hall

WHEN: Sunday, March 22, all day, from 6am until sometime after 7pm.

DESCRIPTION: JHU is planning an all-day power outage for Malone Hall. As such, all of our computing services will be unavailable during that time.

The actual power outage is planned to start at 7am and end at 7pm Sunday, March 22. 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 6am that morning. We will then bring the systems back up after 7pm (when the power outage is declared over.)

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, and 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 to be in the building during that time. If you have an office refrigerator, expect that to be out too. And, if you are counting on UPS (battery-backup) systems you have to power up your office equipment, please realize that this is an expected 12-hour outage. And, keep in mind that your office phones may be inoperable during the 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.

CS IT services unavailable during the power outage include:

  • CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users.
  • CS DNS-based lookups will be unavailable.
  • Incoming mail should be queued by the sender until our mail service is back up again. Outgoing mail will not be available.
  • IMAP, POP, and Webmail from our CS (Grad/Research Net) Mail server will be unavailable. And, although, CS Ugrads can send email through the JHU webserver, their incoming mail arrives at CS, so Ugrads won't be able to see their email.)
  • No CS webpages will be available.
  • Grad/Research Net and Ugrad Net user accounts and home directories will be inaccessible during the power outage.
  • SMB File Shares (CS Office Staff uses these) will be unavailable.
  • 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 to any of our lab Linux clients systems 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.
  • Wifi access points in the building will be without power, so no wifi.
