This week we were working on what we thought was a web site certificate issue when it dawned on us - someone altered the DNS records for the domain without our knowledge.
How did this happen? Because the company's domain name is not registered to the business. It's registered to a third party. And we see this more often than not.
Since the third party owned the domain name, important entries were removed without any notification. You'd think they'd check with the user first to understand why the entries were there.
