About this blog…

I am employed by Netnod as head of engineering, research and development and am among other things chair of the Security and Stability Advisory Committee at ICANN. You can find CV and photos of me at this page.

As I wear so many hats, I find it being necessary to somewhere express my personal view on things. This is the location where that happens. Postings on this blog, or at Facebook, Twitter etc, falls under this policy.

The views expressed on this post are mine and do not necessarily reflect the views of Netnod or any other of the organisations I have connections to.

Facebook down?

I was checking a post I got a link to from a friend, and did not get any content, but the browser did not say anything weird. So I checked with the trustworthy curl library…

Nope, it looks not good at all. Ok, maybe the closest cache that is broken.

Lets check with one of the more broad test sites.
