<!-- == Results of the 8/14 outage. ==
 
The planned outage from the morning of 8/14/13 is complete, and our servers are back up.  If you're experiencing any problems connecting to our systems (logging in or sending or receiving CS mail), please e-mail [mailto:support@cs.jhu.edu support@cs.jhu.edu] as soon as possible with a complete description of your problem.  The more info you can provide us, the easier it will be to troubleshoot.

We need to know what machine you're trying to ssh into *and* from what IP you're ssh'ing, as well as a detailed description of the error you're experiencing.

If you're experiencing issues connecting to our smtp.cs.jhu.edu mail server to send e-mail, please provide us your client's outgoing mail settings, including security type and whether you have it set to require a login.  Please do not send us passwords. 

If you're having issues receiving e-mail from our pop.cs.jhu.edu (pop and imap) mail server, please send us as much of your imap or pop configuration info as you can.

<!-- None at this time. -->

<!-- '''Wed, July 30, 9am through noon:'''  ''Entire Undergrad Net'' (clients and servers) will be down as we complete system maintenance and move some equipment to a different rack.

Additionally, the Ugrad Net web and mail service will be unavailable during that time.  (Incoming ugrad net mail should queue up on another of our mail servers during that time, until the ugrad mail server is back up and running and transfers the mail.)  -->


'''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 will last until 6am (or earlier) 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  You may notice a delay in DNS name resolution when falling back to the secondary server.

* ''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.)
