* ''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

* During the lab closure times, compute servers, gradx.cs.jhu.edu, gradz.cs.jhu.edu, ugradx.cs.jhu.ed, and ugradz.cs.jhu.edu '''''will continue to be available remotely''''', via SSH.

* We have to take down the lab systems late that Friday afternoon.  At the end of the ACM contest that Saturday night, the coordinators of that contest will be turning our lab computer systems back on.  Most should boot normally.  But, if some do not, just trying using an alternate one in the lab.  We'll be back in the Monday afterwards and can check on any systems that didn't boot normally.  (And don't forget, as mentioned above our compute servers -- gradx, gradz, ugradx, ugradz -- will continue to be remotely available, even if the lab systems are not.)
