Speaking of bandwidth, the CCH internet infrastructure can not support 12,000 hackers, so they bring their own network. This is the task of the CCC Network Operation Center (NOC). In the Infrastructure Review (see video) at the end of the congress Leon and Marcus of NOC gave an overview of what the team had accomplished and the troubles on the way to get there.

A week before congress the sponsor that had provided the backbone equipment in the previous years had to withdraw. The team responded by making a lot of phone calls asking people to bring their hardware. The result was a lot of Fritzboxes. Despite the woes the network reached a maximum outgoing traffic of 21.4 gigabits per second, 4 Gbp more than the previous year.

The Infrastructure Review also details the work of the Video Operation Center which recorded and streamed 134 hours of talks with real time translation from English to German and vice versa. All the talks are now available on the CCC website.

Here is a pick of the talks of the CCC main track that touch both on technology and ethics:

The Exhaust Emissions Scandal („Dieselgate“)
Daniel Lange and Felix Domke provided insight into Dieselgate. Lange, who has worked for years as head of IT strategy at BMW explained the political and engineering landscape in which the cheating on emission tests could occur. Domke hacked his own Volkswagen and an Engine Control Unit to find out how the software was set up to trick the tests.
