Has anyone verified that this actually works? My company's DNS administrators have already made this change. use-application-dns.net returns SERVFAIL when I run "dig" on my machine on the corporate network. But if I enable DN

It has benefits for the ISP, too. I used to work at a small-medium regional ISP. Something like 50-70% of ALL traffic was streaming video and specifically Netflix. We weren't big enough to get into their version of this program at the

This isn't accurate; they've been separate companies for years now. It's kind of a winding history but the TLDR is TripAdvisor started out as an independent startup. Was purchased by a large holding company, which also owned

First of all, yes, people should be using multiple DNS providers for services that require very high uptime. Amazon.com itself notably uses Dyn and UltraDNS as its nameservers. That said, I'm not sure this would have helped in this cas

I agree with you. Bare metal to me always implies, well, actual physical servers made out of metal :) A better title might have been "Kubernetes Without a Cloud" or "Kubernetes on-premise". Since what the author is tryin

We run Arista 7280SR's on our edge. I went looking, and as far as I can tell, the TTL is NOT part of the default ECMP algorithm on this platform (Jericho chipset)? We certainly haven't tuned this setting one way or another. I woul

This is a feature of iOS and macOS, at least. If you have a wifi network's password saved in your device, you can bring it physically close to another device that doesn't and it will ask whether you want to share. You have to affi

This is also the function of the "deflector" on ships in Star Trek. The idea being that when you're traveling that fast, even the tiniest debris will ruin your day, so you need something to push it out of the way.

Piling on what others have said, the Web wasn't even a thing until the early 90's. There was minimal commercial value in a domain name at that point, so no incentive to squat on it and try to extort money. What did your average bu

Agree with the other commenters, very interesting insight. It maybe doesn't fit the metaphor quite as well, but as an operations person, I've frequently run into the "underfitting" problem. For example, we run Chef to ma

No, BGP is actually terrifyingly easy to hijack and it's surprising this doesn't happen more often. There's really nothing at the protocol level to indicate that the router you're peering with is actually authorized to a

As a kid who grew up in Massachusetts in the 80s and 90s, I'd love to go back in time and experience the competing tech that was being built in my back yard before the west coast totally won out. I had friends whose parents worked for

Arvada is still a decent place to live if you want to be on the north side of Denver. Otherwise, look down out to the south and/or west so you can at least be on the light rail. I think you are maybe talking about Commerce City with th

It's implied by their claim that there is a single responsible individual. If someone else reviewed it and said "yep, looks good, deploy the change" how is there one "individual responsible"? The idea of an isolated

I found "BGP4: Inter-domain Routing in the Internet" by John Stewart III [0] to be very approachable. It's likewise ancient by tech world standards (published in 1998!) but that's because, amazingly, BGP has not fundamen

Yes, this. Cloning a git repo is not a reproducible build and deploy strategy, especially once you scale past one developer. Building a package (RPM/DEB/Docker container/whatever) once, and promoting it from dev through to te

Depends what you want to get out of it. I used it for a year to host a crappy blog that got trivial amounts of traffic. It's perfectly fine for its primary use case of getting your feet wet in the AWS ecosystem, learning what all the d

Yeah, definitely. The bigger takeaway is probably that you really want to have more than one DNS provider. Assuming whatever you're running is important enough to justify the cost. If DNS ain't happy, ain't nobody happy ;)

We balance our domains across Dyn and UltraDNS. No complaints about UltraDNS so far. Has just worked, and they have a decent REST API which is nice (as does Dyn).

Same here regarding emulation. When I was about 16, I took over project management for the UOX3 emulator for a year or so when the original author abandoned it. I sure as hell wasn't a good enough coder to have written it myself, but I
