PLANNED CS SERVICE OUTAGES

WHAT: Emergency reboot of blaze, the dept's main Grad/Research net mail server.

WHEN: (TODAY!) Tuesday, Dec. 12 @ noon and lasting approx 1/2 hour if all goes well.

DETAILS:

We have discovered an issue with our mail spool disk on blaze our Grad/Research net mail server which must be corrected right away. As such, we expect that a configuration change and reboot should fix the problem.

We plan to do this shortly, at noon today (lunchtime.) The reboot should take approx. 1/2 hour if all goes well. If there are issues, it might take some additional time to complete the repair.

During the reboot time, there will be no CS email service in or out of the CS Grad/Research network. You will not be able to send or receive mail (IMAP/POP/etc.) through blaze (smtp.cs.jhu.edu/pop.cs.jhu.edu) or via webmail during that time. Also, DNS might be slow or non-existent, depending upon your client's own configuration.

You also might experience slow connection times to www.cs.jhu.edu.

Grad Net Lab Linux systems (masters1 through masters16, gradx, and gradz) may experience a short delay as their NIS service connects to a different server.

Any updates and notice of completion will be presented through this NOTICES page today.

UPDATE: 12/12/17 at 12:15pm

Reboot successful! Blaze is back in operation and services have been returned to normal operation.
