Planned power outage for December 10th, at 6:30-6:50am

There will be another power outage on campus December 10th at around 6:30am-6:50am. The server will go offline at about 6:25am, and, hopefully, be back online at about 8:30am or sooner.

Update: the power outage was over by 6:38am. WeBWorK server is up and running as of 8:45am.

Power outage

We had a power outage in Menomonie, WI and on UW-Stout campus today. It looks like power was out between 4:39am-6:27am for the server, with another planned/emergency power outage at around 7:30-7:36.

There were some issues with WeBWorK database due to the first power outage, so I took the server offline at 7:25am until about 9am to recover database. It looks like a few indexes got out of sync with the actual data in the database due to some interrupted operations - that was fixed by 9am today.

New SSL certificate

Thanks to support from Math, Stat and CS department at UW-Stout, our WeBWorK server got a brand new SSL certificate. The new certificate should now be recognized as a valid certificate which, in turn, should eliminate browser warnings.

WeBWorK server might be unavailable tonight

WeBWorK server webwork.uwstout.edu might not be available tonight to anyone accessing the server from off-campus from 8pm Monday, September 27th until 8am Tuesday, September 28th due to some work being done on fiber connection, as was announced via email:

Campus Internet Outage

Off-campus Internet network resources will be unavailable from 8 tonight, through 8 a.m., Tuesday, Sept. 28.

This outage is due to fiber maintenance being performed in the Eau Claire area.

Update:

This just in from our network administrator:
The fiber will be cut (and connectivity lost) at 1:30am Tuesday September 28th. Ours [Stout's] will be one of the first pairs reconnected. They expect the work to be completed on our segment at approximately 3:00am Tuesday September 28th, no later than 6:00am

Move is complete.

The move seems to be complete. The webwork.uwstout.edu server got a new ip address, and seems to be operational.

MSCS Department is Moving

Our department is moving into a newly constructed/remodeled building, which means that webwork.uwstout.edu server might go offline for a couple of days at any moment. More details will be posted when available.

Update: we've moved the server yesterday into the new building. Since there is a scheduled power outage for the whole weekend in the new building, the server is not available now. It should be back online Monday, August 23rd sometime in the afternoon.

Campus Network Outage: 10pm July 29th through 5am July 30th

From UW-Stout Telecommunications and Networking:

Due to a fiber-backbone move taking place in Eau Claire, the campus will be without internet access from 10 p.m., Thursday, July 29, until 5 a.m., Friday, July 30.

I expect webwork.uwstout.edu to be unavailable during that time as well.

Server Reconfigured

Our server (webwork.uwstout.edu) was reconfigured to run 32-bit operating system.

All courses were backed up Tuesday, May 24 at 2pm. They should be back online now.

It turns out that 64-bit operating system requires about 3x more memory than 32-bit OS to run WeBWorK efficiently.

Sunday Outage: 10:35am-12:17pm, May 02

There was an outage this Sunday, May 02 between 10:35am-12:17am. My guess is that the power was down in the building where the server is housed.

WeBWorK server was not available until 10am

Our WeBWorK server (webwork.uwstout.edu) seemed to be unavailable until 10am today. My guess is that the entire UW-Stout network was isolated from the rest of the internet due to some maintenance work.

An update will follow as soon as more information is available.

WeBWorK server reboot at 4:30 today

WeBWorK server will be unavailable for a few minutes today starting at 4:30pm CST due to reboot.

Short Outage Today: 10 minutes sometime between 4pm and 5pm

Our WeBWorK server will be unavailable for a few minutes between 4pm and 5pm.

Update: the outage is over.

Networking Issues on Campus

UW-Stout Campus had some issues with networking this morning. It appears that everything has been resolved already.

LDAP authentication for UW-Stout users

It appears that LDAP authentication for UW-Stout users is not working as expected at the moment. Since I cannot sign on to Learn@UW-Stout system as well, it is safe to assume that the issue is with UW-Stout LDAP authentication servers. I hope the issue will go away by Tuesday.

Server is back online

Our server should be back online with newer hardware up and running.

There are several minor updates and tweaks that we'll be working on for some time, so the server might be in and out for a few minutes at random moments.

An update will be posted when we're done.

Downtime

We're changing server hardware. WeBWorK server webwork.uwstout.edu will be unavailable starting this Friday, January 15th at 6am and until further notice. The intention is to have everything back to normal by the end of the day.
