Wed April 26, 2017, 11:01am - SSH from off campus and VPNs failing [RESOLVED]

After a switch on April 10th to a new firewall for the Med School, we noticed that idle ssh sessions were being killed after very short times. This morning, the SMPH Network Group made a change to reduce that timeout, but now we are seeing incomplete ssh negotiation for new ssh sessions, from off campus and from VPNs. Within the Biostat network, ssh is fine.

The SMPH Network Group is aware of this and debugging the issue now. We'll update this status page when we know more.

Mon, Feb 6, 2017, 1:00pm: File Server Outage [Resolved 10:17pm]

Access to the main file server is intermittent. We're working on it now.

10:17pm Update: File system services to user home directories and project directories are now working again.

There will need to be a scheduled outage (perhaps more than one) to deal with additional clean-up and adjustments. The system might be a bit slower than usual for a few days.

Most machines have recovered on their own from the outage, but a few may be so confused they need a reboot. We'll be checking hosts, but please let us know if you run into any stuck machines.

Critical File Server Upgrade, Wed, March 16, 9:30pm-12:00

As many of you have doubtless noticed, the file server holding your home directories has been misbehaving in recent weeks. To address that, we'd like to take down the file server for hardware maintenance the evening of Wednesday, March 16th, from 9:30pm until midnight.

During the outage your home directory will be unavailable and you'll not be able to log in. Your email, as a DoIT service, will be unaffected by the outage.

We also recommend you not have any CONDOR jobs scheduled during that time.

Jan 15 2016: Python library updates and Git

The Python deep learning support library Theano has been added to Python 2 and 3.

Since the last time we checked, several additional scientific packages have been ported to Python 3 (matplotlib, in particular). So, for the moment, Python 2 and 3 have parallel scientific libraries. Details.

We have recently installed an authenticated, web-managed Git repository tool, available to all Biostat users. Details.

Jan 11 2016 : Project and Compute file server down [Updated 6:44pm]

Status: (6:44pm) the compute file server is back up.

Due to a lengthy power outage in one of our server rooms, a large number of compute machines, and one main file server, were offline since Sunday.

The compute machines are mostly back now.

It seems there was a power surge when the power came back on, which has caused problems for the project/compute file server. We're currently working (9:30am) to move the drives to a different chassis and bring that service back online. I'll update this page when that service is back.
