From around 8 am today, a global Domain Name Server issue disrupted access to Blackboard (and linked) services for some users, while others were unaffected. Whether or not you were affected was due to the route taken through the Internet from your computer to the Blackboard servers. Blackboard put a fix in place soon after the incident was observed, but due to the nature of the issue, this has taken some time to propagate to all users. Blackboard has informed us that a normal service should be restored for all users by 5 pm today.
