Unplanned service outages

gradx - Down at this time. Hardware issues. Undergoing troubleshooting to determine the source of the problem. None at this time.

Planned outages

MAJOR motherboard repair of rtfm.cs.jhu.edu, one of our main CS Grad file system servers, will create up to (but hopefully, much shorter than) 6-hour planned downtime for the Grad/Research Network. Our hardware service/repair company will be on-site completing repairs.

Outage will begin at 12am (midnight), Thursday, 8/22 and last until 6am Thursday.

During that time, the following services will be unavailable:

• Email in or out on the Grad/Research Net will be disabled. (Connections to smtp.cs.jhu.edu and pop.cs.jhu.edu will fail during that time. However, incoming mail to CS should queue at an alternative server.)

• Email on the Undergrad Net will be disabled during this time (as CS Ugrad e-mail addresses are registered via a server on the CS Grad Net.)

• DNS, will only be available if you've configured your computer with a secondary DNS server. If you don't have a secondary server in your computer's DNS defined, please add 128.220.2.7

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

• Access to any of our Grad/Research Net linux clients (including gradx and masters1 through masters16, as well as Dr. Smith's pllab machines that we maintain) will be unavailable

• peregrine.cs.jhu.edu (our Solaris login server) will be unavailable

• Our mysql server, mysql.cs.jhu.edu, will be unavailable.

• Samba shares will be unavailable.

• Your Grad/Research Net web pages will be unavailable. (The webserver is expected to be serving minimal pages, mostly notices, during that time.)
