CSE-IT Major Incident In Progress: Home directory storage, Fri 29-Jun-2018

At approximately 5:45PM on June 19th, CSE-IT began receiving reports of issues regarding its home directory storage servers. Symptoms include logging in to a UNIX system and having only a desktop picture and terminal window available, with no menu bar or launcher. Our analysis indicates a repeating and intermittent bug in our storage servers software is periodically causing the server to not respond to requests, requiring a reboot.

CSE-IT supported websites that depend on a CSE-IT managed database, and CS UNIX accounts

During the CSE-IT maintenance window Sunday morning, 5/20/2018, a firmaware update resulted in some CSE-IT Virtual Server infrastructure becoming unavailable. Services affected include CSE-IT supported websites which depend on a CSE-IT managed database, and Computer Science UNIX accounts.

[Major Incident] – SSH connection shut down abnormally

At approximately 10AM today, CSE-IT began receiving reports of issues regarding  linux systems rebooting.  There was a problem with the scheduler for the task that was supposed to have rebooted systems at 4 a.m. this morning.  That reboot was announced last week.  A full postmortem will be done to find the exact cause of the problem.
