PLANNED CS SERVICE OUTAGES

Planned Outage 1: CS Ugrad Net File Server Upgrade (barley.cs.jhu.edu)

WHAT: Major CS *Undergrad* Net computing services outage, as we upgrade our CS Undergrad Net file server, barley.cs.jhu.edu

WHEN: Wednesday, January 18, from 8am to approx 11am.

DETAILS: Our CS Undergrad Net home directory file server, barley.cs.jhu.edu, will be shut down to perform an major upgrade to its operating system.

Due to this shutdown for repair, several of our CS Ugrad Net services will be unavailable during this time. If there are any unexpected complications during the repair process that will delay the restoration of services, we will update the CS IT Support Wiki's Notices page at https://support.cs.jhu.edu/wiki/Notices

Suspended (Unavailable) Ugrad Net services while barley.cs.jhu.edu is down

• CS Ugrad Mail service, both incoming and outgoing, will be suspended for CS Ugrad Net users (as this fileserver works in tandem with our CS Ugrad mail server.) Incoming mail should be queued until our mail service is back up again. Outgoing mail from CS Ugrad Net users will not be available.

• IMAP, POP, and Webmail from our CS Ugrad Mail server will be unavailable.

• Webpages served from our CS Ugrad webserver will be unavailable.

• Ugrad Net user accounts/home directories will be inaccessible during the downtime.

• ssh service to our CS Ugrad Net Linux boxes (ugrad1 through ugrad24,and ugradx) will be unavailable.

• Console (desktop) access to ugrad1 through ugrad24 will be unavailable. However, although the CS Ugrad computers will be unavailable during the repair time, the CS Ugrad Labs will remain open.

• MySQL service via the dbase.cs.jhu.edu server (used by a databases class) will be unavailable.

Future updates will be posted on the Notices page of the CS IT Support Wiki

Planned Outage 2: Databases Class MySQL Database Server (dbase.cs.jhu.edu) Unavailability

WHAT: The Databases class's MySQL database server, dbase.cs.jhu.edu, will be unavailable when the CS Ugrad Net's fileserver, barley.cs.jhu.edu, is being repaired (see above.)

WHEN: Wednesday, January 18, from 8am to approx 11am.

DETAILS: dbase.cs.jhu.edu uses the CS Ugrad Net file server and will therefore be unavailable during the barley.cs.jhu.edu repair time.
