Blackboard will not be available from Friday 11 August 19:30 hours until Saturday 12 August approximately 12.00 hours, due to the upgrade to a new release. Apologies for the inconvenience.
Please note: when you visit http://blackboard.utwente.nl during the maintenance, a maintenance page will be shown instead. However, your browser will probably first show a warning that the certificate is not valid. The reason for this is that the UT SSL certificate is not valid for the maintenance page (that falls under blackboard.com). Unfortunately there’s no solution for this at the moment.
