UNPLANNED CS IT SERVICE OUTAGES

None at this time.



PLANNED CS IT SERVICE OUTAGES

WHAT: Malone Hall MH 122 and Malone Hall G61, both the Masters and Ugrad sides of the lab, and all the lab Linux computers, will be closed to CS students due to an ACM Programming Contest.
WHEN: Starting Friday evening, November 7, 5pm through Saturday, November 8, 9pm.
DETAILS:
Both the MH 122 and G61 Masters and Ugrad Labs will be used for an ACM Programming Contest and will therefore be closed to those not participating in the contest.
Additionally, all of the labs' Linux computers (masters1 through masters16 and ugrad1 through ugrad24) will be unavailable during the time period referenced above.
  • 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.)
  • The printers in MH 122 and MH G61 will remain online, but, please pick up your printouts outside of the contest hours.
