Whoa! Godaddy issued at least 8850 SSL certificates without proper validation

On Friday, January 6th, 2017, GoDaddy became aware of a bug affecting our domain validation processing system.
The bug that caused the issue was fixed late Friday. At 10 PM PST on Monday, Jan 9th we completed our review to determine the scope of the problem, and identified 8850 certificates that were issued without proper domain validation as a result of the bug. – Godaddy.
