Teaching and research have been disrupted by technology issues on two occasions in the past two weeks, officials said.

Geneva Henry, the dean of GW Libraries and Academic Innovation, said 10 professors reported slow login times to classroom computers on Nov. 6, and users were timed out of GW’s library catalog interface the week before. While the interference with the library catalog was fixed within the hour, technology specialists have yet to find the cause for the slow login times, she said.

Henry said the specialists are looking into the software updates for computers in classrooms because a recent update to the system software may have unintentionally caused the untimely logins.

“The Solutions Center dispatched technicians who determined the best immediate solution in most cases was to give the computers the time needed to log in,” she said.

The Academic Technology department tweeted about “sluggish performance” on classroom computers last week and posted again the next day, saying the problem had been resolved but the cause of the issue had not yet been found.

Professors said having to wait to access their computers caused a disruption during classes.

Tonya Dodge, a professor of psychology, was trying to pull up a Powerpoint presentation early last week in Funger Hall and she waited five minutes for the computer to log on. She said the class was already running five or 10 minutes late, and she didn’t have time to report it and wait for a technician.

She downloaded the slides on her laptop and presented them to the class.

“It was disruptive, but as a professor, you know that you have to have a way to get information,” she said.

Christina Gee, a professor of psychology, was trying to log into the computer network during her class in Monroe Hall on Wednesday. She waited four to five minutes before giving up and using her laptop instead of the provided computer.

She said she did not report the issue because she had another choice and could avoid waiting.

“I had a laptop as an alternative and didn’t want to wait,” she said in an email.

Danny Benbassat, a professional lecturer in the psychology department, said he reported a slow login on a computer in room 151 of Duques Hall to the Academic Technology department last week after waiting a couple of minutes for the system to load.

He said he needed to log in to the computer to use the projector, but by the time staff arrived five to eight minutes after Benbassat reported the issue, the computer had loaded.

“The IT support were extremely helpful,” he said in an email. “Altogether, it was a minor inconvenience.”
