PLANNED SERVICE OUTAGES



Planned Service Outage

WHAT: blaze.cs.jhu.edu (CS Grad/Research Net's mail server, NIS server, and dept's DNS server) will be rebooted.

WHEN: Tuesday, May 24, starting at 7am. Reboot should take around 10 minutes or less, but, we're going to say the process might take up to an hour, just in case any issues arise.


DETAILS: One of our main servers, blaze, requires a reboot to activate some settings.

During that time, there will be no CS email service in or out of the CS Grad 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.

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 (delays, etc.) will be found on this page.
