## Abstract
DNS is one of the few remaining (generally) unencrypted parts of our daily network use. In addition, TLS sessions (even TLS 1.3) transfer the name of the server visited in plaintext ("SNI"). 2018 saw the release of technologies to encrypt both of these privacy leaks, which is good. Less good however is that with this encryption, your DNS (and TLS SNI) lookups will move to the cloud.
In this talk, I explain the technologies used (DNS over TLS and DNS over HTTPS), but also spend time on what this change means: loss of control over your lookups (forget about your intranet), and how encrypting your data to a cloud provider may provide security against your network admin & government, but does send all your browsing behaviour to California.
## Biografie
Bert is the founder of PowerDNS. These days he also cares a lot about keeping the internet open. In addition, he can't help document or explain open technologies.

## Abstract
A major asset of the NLUUG is the service of the FTP server. The FTP archive is a service for the open source community, and mirrors a very large number of open source packages.
In this talk we describe the history of this major hub of global software distribution and show the people and technology (ao. hardware, software and networking infrastructure) that we use to run this service now and in the near future. The method of mirroring and procedure to have a new content mirror attached will be discussed as well.
