You’re looking at your todo list and pondering what code to write during one of the brief moments of free time that appear on your daily schedule, when all of the sudden you get a message in team chat: Is the site down for anyone else?
It can be a frustrating experience, but never fear; you’re not alone. We here at &yet experienced this type of outage once before, and then again this week. In fact, nearly every operations team has experienced at least a variation on the above nightmare. It is just a matter of time before you have to deal with people thinking your site or service is down when the problem is really with the Domain Name Service (DNS). Even shops that spend a lot of money to work with DNS vendors who themselves have some serious redundancy and scale will eventually fall prey to an orchestrated Distributed Denial of Service Attack.
