Several Web sites that require users to log in with their PennKeys for access - including PennPortal and Blackboard - were unavailable for several hours on Sunday afternoon due to problems with the server that allows for PennKey authentication, according to Robin Beck, vice president for information systems and computing.
The University is still investigating the exact cause of the problems with the sites.
The University had planned for rolling outages with the PennKey authentication server to allow for upgrades, but unexpected problems occurred and caused several sites to be unavailable for a longer-than-expected time, Beck said.
The inability to access the Web sites was not caused by Blackboard and PennPortal, she said, but by the server that authenticates PennKeys and gives access to those sites.
Blackboard, PennPortal and other sites were unavailable Sunday from 10 a.m. to noon and from 2:40 p.m. to 7:10 p.m.
