Good day,

We have just uploaded the following data sets we mention in our IMC paper.

Certificates found different between location China-1 and TUM, Apr 2011
Certificates found different between location China-2 and TUM, Apr 2011
Certificates found different between location Moscow and TUM, Apr 2011
Certificates found different between location UCSB and TUM, Apr 2011

All from university networks (PlanetLab). The data sets contain host
name, cert as seen from remote location, cert as seen from TUM.

The download location is:

http://pki.net.in.tum.de/

We did not have the time to go through the many hosts and certs,
although we did take a thorough sample (and found nothing clearly
suspicious).

We have promised in the paper to offer these data sets to other
researchers so they can have a look. Since the distributed observatory
is now out, too, we hope this may be useful.

Ralph
