Move over Jurassic World, the long awaited sequel to our Tokyo deployment is here. Our Osaka data center is our 2nd in Japan, 5th in Asia (following deployments in Hong Kong, Tokyo, Singapore, and Seoul), and 35th globally. This latest deployment serves not only Osaka, Japan's second largest city, but also Nagoya, the 3rd largest, and the entire Keihanshin metropolitan area including Kyoto and Kobe. This means faster application delivery to the area's 30 million inhabitants, and full redundancy of traffic with our Tokyo facility. CloudFlare is now mere milliseconds away from all 110 million Internet users in Japan.
Even though Asia is home to many of the most technologically advanced nations in the world, the delivery of Internet traffic across the region is hardly seamless. Many of the incumbent telecommunications providers in the region (e.g. NTT, Tata, PCCW, Hinet, Singtel, among many others) do not interconnect with one another locally. This is another way of saying that traffic is routed poorly in the region. Traffic sent from one network in Japan, for example, may have to pass through an entirely different country or, in some instances, even the United States, Continue reading
Containers, IPv6 and “SDN DNS” is why DNS is critical to your network architecture and day-to-day operations. At the same time, "DNS operations" doesn't seem to be getting the attention considering how critical it is to network, servers and DevOps alike. I wonder if I am missing something.

You’re asked to update the SSL certificate for movingpackets.net on a load balancer. The requestor (me, I suppose) gives you the certificate, the private key and passphrase, and the intermediate bundle file provided by the certificate authority.
movingpackets.net.crt
movingpackets.net.key
movingpackets.net-intermediate-chain.crt
You faithfully go to the load balancer, upload the files, enter the passphrase, and create a client SSL profile referencing the cert/key/chain combination I provided, and all is well. The only thing is, you have 200 VIPs on the load balancer, mostly issued by the same certification authority (CA), so don’t they nominally share the same intermediate chain? (Hint: Almost certainly, yes)
Here is the operational annoyance. The fact that the same intermediate certificate/chain has been uploaded 200 times with different names doesn’t stop things working, but it does seem rather inefficient. As far as I can determine, the F5 LTM load balancers (for example) actually concatenate all the uploaded certificates into a single bundle file and search the bundle when a certificate is referenced. I have no idea if there’s a huge performance gain here (unlikely), but it seems logical to want to minimize that file size regardless. On other Continue reading

[P]re-acting to something that hasn’t happened yet is nonsense.
Refusing to learn from people you don’t agree with isn’t a particularly modern vice, but in our world of information overload, where there are so many voices that we can choose to listen only to people we agree with, it does create a particularly modern narrowness of mind.

Startup wants to put containers right next to the databases they crave.
I’m betting that I could take my certifications off my resume and still have a fair chance at finding a job. It’s a guess, of course, and I’ve never tried any sort of an experiment towards finding out, but the point is this: at some point in your career, certifications should become just one more thing on an excellent resume, rather than the focal point of your resume. Given this, why do I still support certifications? To answer this question, I need to back up into the certification development process a bit.
One of the strangest “mind trips” I’ve ever encountered was working with the “psycho’s” (psychometricians, really, but you know how engineers are with long words) through the entire CCDE/CCAr process. The two things we were challenged constantly were:
Both of these are hard questions.
The first question we turned into a simpler one (again, you know how engineers are): Why do I care? When someone would suggest a particular question or skill, they were immediately met with the counter — Do I care? If I were a designer working on a Continue reading
