Hi all,

Rob Sayre has pointed me to this thread. I am an author of the linked paper.

He has pointed out some confusing and outdated information in the paper, that I would like to clarify: The version currently available at http://eecs.qmul.ac.uk/~boettget/assets/doh-imc19.pdf was created and correct as of October 2018. In the meantime, things have changed, Google for example today also supports DoT and TLS 1.3 (c.f. Table 2). We are currently working on an updated version which includes changes in the available services as well as explicitly lists timestamps when the data was collected. This version should hopefully be available by end of this week.

If you have further comments, though or feedback on the paper, please feel free to share, I would love to hear them.

Once again, Rob, thanks for pointing me to this thread.

Cheers
Timm
