NetApp fileserver downtime in preparation for upgrade – Phase I: Monday, June 10, 6-8pm

NetApp filers are due for their 4 year refresh cycle. Work on this has commenced, with new NetApp hardware on site. New filers are going to be added and data migration will occur some weeks down the road. While most of the work will be non-disruptive, some elements will be disruptive.

The first of this will happen on 10th June Monday, and the scheduled downtime will be from 6-8pm, to incorporate some network changes. All NFS and CIFS access to the filer (home and project storage) will be down during that time.

Network outage at department border

Staff are investigating a network outage affecting all EECS network hosts. The outage began at about 6:25am September 22.

At this time, it’s unclear whether the outage is due to EECS network equipment, or upstream with campus networking.


UPDATE: Cause was due to a loss of default routes normally advertised by campus BGP. The issue was isolated and the campus NOC restored the routes shortly before 10AM.
