ORIGINAL POST: There is a known issue with Blackboard Collaborate Guest links cause some users to see a "Not Found" error page. This issue will be addressed by Blackboard Inc, and we hope to see it addressed soon. Until than, the work around is to log out of Blackboard Learn. For full details on the issue, please see the FAQ article "Collaborate Link Returns "Not Found" error page"
On Sunday July 17th, our Blackboard Learn server will be down for maintenance. You will not be able to log into Blackboard Learn on the 17th. Please be aware that for July 18 through July 20, we will be preparing our Blackboard Learn environment for the 2016-17 school year. During this time, you may find your Blackboard Learn experience to be inconsistent (color changes, box/location of links change, etc) but we do not expect any additional downtime after the 17th.
UPDATE: Google has reported that service has been restored:
The problem with Google Calendar should be resolved. We apologize for the inconvenience and thank you for your patience and continued support. Please rest assured that system reliability is a top priority at Google, and we are making continuous improvements to make our systems better.
