Some users were unable to access Blackboard
On April 25th, a change was executed to enhance our DNS services to prevent DDoS events like the one that took place on 4/20. This change was not successful which propagated incorrect DNS information across the internet. The change was rolled back but DNS is a pull- based request and took time to propagate the correction across the internet.
Some users needed to flush their DNS cache or contact their internet provider to flush at ISP level.
Anthology fixed and re-executed the upgrade to DNS services to prevent issues like the one experienced on 4/20.
