JHU IT SERVICE OUTAGES AFFECTING CS IT SERVICES

=== PLANNED JHU SERVICE OUTAGES === --> JHU OUTAGE AFFECTING CS:

WHAT: potential multiple less-than-10-second power outages in Malone Hall (& Hackerman)

WHEN: Thursday, July 25, from 3:30am through 6am.

DETAILS:

JHU Networking has indicated they are testing power transfer equipment in Mason Hall that will affect several buildings, including Malone and Hackerman. They will be cycling power to the buildings, perhaps several times. They expect their outages to be < 10 seconds each.

Our CS IT servers that provide you most of our IT services should remain up and running, since our servers have backup battery power. Unfortunately, the JHU network in the building does not. So, you will probably experience brief network interruptions when the power is cycled by Facilities.

Faculty who run their own servers in the CS Server Room (MH G-29), please note that if you do not have UPS units in your racks (and most of you do not), you can expect your systems will power cycle each time Facilities cycles power in Malone Hall. Please be aware. PhD students who maintain those systems (and perhaps other systems in the building), please keep that in mind as well.

The CS computing labs' systems (currently, for the summer, all located in G-61), those computers are not on UPS systems, so those computers will power cycle and should boot back up on their own.
