Drop support for managing NN.dl.amnesia.boum.org DNS records for mirrors
Originally created by @intrigeri on #17593 (Redmine)
Years ago, when we switched to requiring HTTPS from our mirrors, we
didn’t want to assume mirror operators would be able to get a
certificate for a hostname they control, so we offered them to create
NN.dl.amnesia.boum.org
DNS A records pointing to their server.
The last mirror that was using this facility was removed from our pool
in November 2018.
AFAIK, nobody requested such a DNS record since.
We have no shortage of mirrors.
So, I’m hereby proposing we drop support for managing
NN.dl.amnesia.boum.org DNS records for mirrors.
This will simplify the doc for mirror operators, our internal mirrors
team doc, and the DNS management code.
- [x] tails.git: doc for mirror operators, design doc
- [x] Puppet: drop support for mirrors.git:subdomains.txt
- [x] mirrors.git: drop obsolete info from README.mdwn
