SIPNOC 2014 – Is It Time For TLS for SIP?


Is it time for TLS for SIP-based Voice over IP(VoIP)? At SIPNOC 2014 on June 10, 2014, I spoke about how to secure VOIP communications using TLS and what are both the challenges and benefits.

Facebook’s Staggering 2015 Q4 Results – Amazing (and Concerning) Numbers!

Facebook quarterly results 2015Q4This week Facebook released amazing quarterly results for Q4 of 2015 that truly show what a HUGE hub of activity Facebook has become. Mark Zuckerberg posted this "Comunity Update" photo with these staggering numbers for monthly active users (MAU):
  • 1.59 Billion monthly Facebook users
  • 900 Million monthly WhatsApp users
  • 800 Million monthly Facebook Messenger users
  • 400 Million monthly Instagram users

Wow.

Consider that there are 7 billion people on the entire planet... 7.3 billion if we go with US gov't data... that's about 1/5th OF THE WORLD (21%) USING FACEBOOK each month!

And nearly 1 billion people using WhatsApp.

Amazing numbers!

Admittedly, I'm more than a bit concerned about all of this communication being centralized within one corporation. This gives a HUGE amount of power to one corporate entity to be the gatekeeper of content and communication. Already with the NewsFeed algorithms Facebook is controlling what we see and share. As these numbers grow, they continue to gain more and more control.

As I wrote about last year, Facebook's control of multiple "user directories" severely limits the ability for new entrants to enter the messaging and communication scene.

It's definitely concerning... but it's also amazing.

Congrats to all the people at Facebook, WhatsApp and Instagram for hitting these incredible numbers! It will be curious to see what next quarter brings!

P.S. Those who want deeper details can dive into Facebook's 2015 Q4 Earning Report. LOTS more data...

Remembering Challenger… 30 Years Later

Space Shuttle Challenger Lifts Off

There are moments in life where you can remember exactly where you were... moments that live with you forever.

Today was the anniversary of one of those.

I was a freshman at the University of New Hampshire in Durham, NH, and remember being in the "lounge" of Sackett House, one of the "mini-dorms" at UNH, where there was the only TV. (Things were different then.) I remember being there with another resident, a woman named Alison, I believe, who dreamed of being an astronaut and was in the Air Force ROTC program to start down that path.

My memory is hazy after 3 decades about the exact details... but I seem to recall that it was just she and I in the lounge area watching the launch. Her dreaming of being an astronaut, and me dreaming of flying into space and space stations and moon bases and more. I was then and still am a dreamer about all things related to space.

Living in New Hampshire we were of course caught up in the massive attention focused on Christa McAuliffe, the first "teacher in space". The media attention was focused on our state - and particularly Concord, NH, where she taught.

But even with all that massive media attention, we probably were the only ones watching in our small dorm... at that point in time Space Shuttle missions had come to be pretty routine... and "boring" to most people. Wikipedia's list of Shuttle missions shows that there were 9 launches in 1985 and in fact the Space Shuttle Columbia had just launched on January 12, 1986, and landed on January 18.

But the Challenger launch 10 days later was anything but routine.

I remember sitting there watching the launch... and then I just remember the fireball that none of us can ever forget.

Booster Plume and Expanding Ball of Gas

I remember the hope... the hope against hope... that maybe, just maybe... someone had survived.

And then the despair when it was clear that nothing could have survived.

I remember Alison in tears... I assume I was probably in tears, too.

I remember that we, as a nation, joined in a collective moment of shock... and then mourning.

The histories tell me that the explosion occurred 73 seconds after launch. Watching one of those original news reports today it seems such a long time.

Later, of course, would be the endless hours of replays... the hearings and investigations... the learning all about O-rings and cold temperatures... and so much more.

Two-and-a-half years later, the Space Shuttle flights would finally resume with great safety improvements - as well as a heightened awareness in the public. Spaceflight was no longer "routine".

But at that moment on that January day in 1986, we who dreamt of space flight watched our dreams be shattered... and the emotional effect lingers to this day.

30 years... 3 decades... seems like such a long time.

But that day... that moment... that image... will live with me forever.

I remember... and I give thanks for the crew of the Challenger... and all of those who have given their lives in pursuit of dreams.

May we all together carry those dreams forward...

Updated DNSSEC Deployment Maps Available on Deploy360

DNSSEC deployment map

Today I’ve updated the page showing DNSSEC Deployment Maps over on the Deploy360 site.  The maps are generated each Monday and sent to a mailing list (to which you can subscribe) and the latest versions are always available in the mailing list archives.  However, from time to time I update the page to show the latest maps so that people can easily find them.

By the way, the latest ccTLD to sign with DNSSEC was Azerbaijan’s .AZ domain!

Azerbaijan (.AZ) Becomes Latest ccTLD To Sign With DNSSEC

Azerbaijan signs .AZ with DNSSEC

Earlier this month Azerbaijan’s .AZ became the latest country-code top-level domain (ccTLD) to sign the domain with DNSSEC and complete the first step in allowing all domains underneath .AZ to obtain the higher level of security possible with DNSSEC.    This is, of course, just the first step.  As we outline in our tutorial, the next steps are that registrars and DNS hosting providers for .AZ need to now support the DNSSEC-signing of domains.  But it’s a good step to see!

We saw this signing come through on Rick Lamb’s DNSSEC Deployment Report and could easily verify it on the command-line using the command “dig dnskey az.” which shows the relevant DNSKEY records. (As well as “dig ds az.” that shows the existence of the DS record.)

A great step forward for Azerbaijan – and we look forward to seeing even more of the countries on our DNSSEC Deployment Maps filled in with green over the months ahead!

If you want to get started with DNSSEC, please visit our Start Here page to begin!
