| − | ====Outage #2: CS Labs/Systems Will Be Unavailable====
| |
| − | :'''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.

| − | | + | |type=Planned outage |
| − | :'''WHAT:''' WiFi and Ethernet connections will not be available on the ground floor of Malone Hall during an upcoming JHU-planned networking outage.
| + | |time=Wednesday, January 14 and Thursday, January 15 |
| − | | + | |services=gradz and ugradz |
| − | :'''WHEN:''' JHU's Planned Network Outage – Wednesday, August 27, 2025, from 8pm through midnight.
| + | |summary=We will need to shut down two of our [[:Category:Linux Clients|Linux clients]] for maintenance. The two clients are gradz and ugradz. They might be unavailable for as much as two days, depending on how long the maintenance takes. Please use our other Linux clients during the maintenance window.}} |
| − | | |
| − | :'''DESCRIPTION:''' JHU is planning a network outage at Malone Hall to install new networking equipment. The outage will start at 8:00 pm and is expected to last between two and four hours. During the outage, the wireless access points on the ground floor will be offline, as will most of the Ethernet jacks. Please be prepared to not have any network connectivity on the Malone ground floor during this time. | |
| − | | |
| − | :Ethernet connections in the Malone server room, G29, will not be affected by this outage. Any servers in G29 should remain accessible. The Linux clients and Ethernet jacks in room G61, which contains the ground floor masters and undergrad labs, will not be affected either. (But any laptops brought into G61 during the outage probably won't be able to access the wireless network.)
