After Yale Bluebook experienced glitches Monday afternoon, including problems with its schedule worksheet feature, the site is back to running normally.

Still, University Registrar Gabriel Olszewski said users of the site may notice class times missing temporarily – for about 15 minutes — while the site refreshes its course information. Information is refreshed at 7 a.m., 10 a.m., 1 p.m., and 6:30 p.m.

He said the website had problems yesterday from about 1 p.m. to 6:45 p.m., when it was “sluggish” and class times were missing, causing courses not to appear in students’ course worksheets. As of Tuesday morning, these problems had been fixed, and no data about students’ worksheets was lost, he said.
