JHU IT SERVICE OUTAGES AFFECTING CS IT SERVICES

PLANNED JHU SERVICE OUTAGES

WHAT: Potential 1 to 2 minute power outage in Malone Hall

WHEN: Saturday, June 26, starting at 8pm

DETAILS:

JHU Facilities is preparing for BGE to test electrical equipment that affects several Homewood buildings. They will be performing this test on Saturday evening, June 26 at 8pm. If you recall, back on May 6, there was a very short power outage that affected our building and others. The testing BGE will be doing is part of their troubleshooting what happened in May.

In the case of the upcoming 6/26 testing, there is a potential for another short power outage (1 to 2 minutes) that evening.

An outage will affect our CS servers and IT services in the following way: Although our servers should physically stay running, as they are on battery-backed equipment, because our services require network connections that are controlled by JHU (and not on battery backup), all of our CS IT services will be unavailable during the expected brief outage.

Once the power returns, our services should be available again, because the network should be available again.

Also, if there is indeed an outage, the CS Grad and Undergrad Lab systems (that currently, you can only access remotely) will power off. However, when power is restored, those lab systems will automatically reboot.

Other notes: WiFi and other networking in the building would be unavailable during the outage. Most likely, lights would be unavailable. My group does not maintain J-Card systems, so we do not know how the J-Card readers will perform doing a power outage.

For your own equipment, please prepare as for any other planned outage.

If there are additional details that we hear of, we will update here.

CS IT SERVICE OUTAGES

UNPLANNED CS IT SERVICE OUTAGES

Issue with Grad Net Self-Service File Recovery

• WHEN: Started around October 30, 2020
• WHAT: Intermittent errors while using self-service recovery

• DETAILS: The /users/backup directory used for Self-Service File Recovery on the CS Grad Net Linux clients may be sporadically unavailable, due to a software bug. Although you may still attempt the self-service recovery, until further notice, if you need a file restored and are having issues accessing the /users/backups directory, please request restoration from our offline backups.
  
  We are working on getting a fix for it, but it might be some time before that fix is available.
  
  NOTE: Self-Service File Recovery continues to be available on the CS Ugrad Net.
