  • There are lots of reasons to use really low TTLs, but most are a temporary need. Most of the times I had to set low TTLs for records were for hardware migration projects where services were getting new IP addresses. But in a well managed shop this should always be temporary. The TTL would be set low the day before the change, then set back to a normal value the day after the change. I feel the author is correct in that permanently setting low TTLs just covers up a lack of proper planning and change management.

    The only thing off the top of my head that I can think absolutely requires a permanently low TTL is DNS based global load balancing for high uptime applications. But I’m sure there are other uses. I agree that the vast majority of things do not need a low TTL on their DNS record.














  • I mean, I have literally overheard a cruise ship ‘tourist’ disembarked in Cozumel, Mexico, loudly complaining about the lack of English speaking staff in the surrounding restaurants and stores.

    The hilarious part is, just about every Mexican working in that part of the island speaks great English, since tens of thousands of cruise ship morons get offloaded in that same spot 6 days a week.

    I’ve traveled all over this planet. If you’re having actual, real problems communicating with locals, it’s probably because you’re an asshole.
