ITS unsure of what caused Sakai issues

The site’s unreliable performance lasted throughout peak class hours, from 9:45 a.m. to 2:20 p.m.

“There were up to 4,000 sessions still going on, but there was also equal evidence that maybe half the requests throughout that period were failing,” said Mike Barker, assistant vice chancellor for teaching and learning at Information Technology Services.

Barker said patches applied to the system during regular maintenance early Thursday morning may be related to the outage, but ITS is not yet certain.

“We do not have an analysis of the ultimate cause,” he said.

Even without a complete explanation, Barker said ITS can take steps to prevent future problems.

“We do what we did today, which is go back to the most recent known good state,” he said. “We monitor all the systems, and we have folks attend to all of those systems and their interactions on a 24/7 basis.”

The outage prevented freshman Jon Mackanic from turning in a chemistry lab report on time.

“I recently hurt my leg, and I’m on crutches,” he said. “I couldn’t really go to the first lab, cause that was kind of dangerous, so I had to make up the lab and turn it in on Sakai.”

“But when I got onto Sakai, it was down and I couldn’t get onto it, so I turned in my lab 20 minutes late today.”

Karen McIntyre, a journalism Ph.D. student, had trouble accessing Sakai to walk her students through group project instructions.

“It was just at the beginning of class, so we just continued talking about other things, and then I came back to it probably a half an hour later and then it was up and so then we went through it,” she said.

Sophomore Archer Boyette said she was also inconvenienced.

“I went to go check (my syllabus), and also print it out, and it was like Sakai’s not up. And well — I’m not allowed to have profanity in the paper — so I was like ‘Dang it. This is unfortunate,’” she said.

Barker said the Sakai problems were unrelated to Wednesday’s CCI printing outage. He offered a sincere apology for inconveniences caused for students and faculty.

“Oh, God no. It wasn’t sched uled. This was an emergency, and a surprise, and a crisis.”
