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.

www.google.com, what is happening?

When looking up www.google.com in DNS, some new things happens. Have a look at this. Unfortunately I do not know what it was before this. How many people will get problems?

Updated: It seems to be one of the nameservers for the l.google.com domain that is releasing what I would call too many records. Yes, I have been in contact with friends at Google. Things are under control.
