Planned outages
None at this time.
Major upgrade of blaze and moving other servers into new rack locations will create a 6-hour downtime for the Grad/Research Network.
Outage will begin at 12am (midnight), Wednesday, 8/14 and last until 6am Wednesday.
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 on blaze.)
DNS, when using blaze as your only DNS server, will be unavailable. blaze is the dept's primary DNS server, however, DNS should fail over to a secondary DNS server, if you have one defined. 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.)
