I'm not sure why we used ansible_fqdn in the first place as
inventory_hostname should be preferred (as we define it ourselves).

From OpenSSH 9.8 release notes [1]:

It has been disabled client side since 7.0[1] (2015-08-11), server side

disabled since 9.1[4] (2022-10-04) and with 9.8[5] (2024-07-01) DSA
support is disabled by default at compile time. In other words, DSA has
de facto been disabled (by default) for years.

From the 9.8 release notes[5]:
"OpenSSH plans to remove support for the DSA signature algorithm in

Enable HTTP/3 for {,aur.,wiki.}archlinux.org

See merge request !850

They are our HTTP/3 guinea pigs for now. HTTP/3 has been enabled on
archlinux.org since 2024-07-22, so I do not expect any issues.

$http_host is changed to $host for aurweb, as HTTP/3 uses the
":authority" pseudo-header instead of the "Host" header[1][2].

[1] https://trac.nginx.org/nginx/ticket/2281
[2] https://mailman.nginx.org/pipermail/nginx-devel/2024-January/LCIUMLKCM2EBMEMTU3KXMW74AP2C4FYZ.html

Ref #606

We want to roll out HTTP/3 slowly, so this adds the necessary plumbing
and makes it possible to enable it per host.

Instead of adding the conditional logic to each nginx template, the 443
listen config is moved out into a snippet which is managed by the nginx
role.

HTTP/3 uses QUIC which is built on UDP. UDP is connectionless and
therefore reuseport[1][2] must be used to ensure that UDP packets for
the same QUIC connection is directed to the same worker. reuseport can
only be enabled once, so a default_server is added to the
"inventory_hostname vhost" for SSL/QUIC (reuseport is only enabled for
the latter). ssl_reject_handshake[3] is enabled as that allows enabling
SSL/QUIC without specifying a certificate.

docs: Make the Junior DevOs program mandatory

See merge request !853

When you become full DevOps you are basically handed the keys to the
kingdom, for this reason alone, access should not be given too easily.
Making the Junior DevOps program mandatory will ensure access is given
out in incremental steps.

The pair programming requirement has been reword to reflect the reality,
as we never really did pair programming.

Fix missing HSTS header for some URLs due to nginx "directive inheritance"[1]

Closes #608

See merge request !859

F5/nginx has blogged about this[1] and it is also mentioned in nginx's
documentation[2]:
"There could be several add_header directives. These directives are
inherited from the previous configuration level if and only if there are
no add_header directives defined on the current level. "

The problem occurs when add_header is used in a child context like a
server{} or location{} block. It is solved by moving the HSTS header
into a snippet, which is now included before all add_header lines.

For now the HSTS header is the only global header, but in the future we
may need to add more global headers, like the Alt-Svc header[3] for
HTTP/3.

archwiki: Do page view caching[1] with nginx for improved performance

Closes #315

See merge request !846

This should not cause any issues as MediaWiki should purge stale content
from the cache (by sending a PURGE request to the nginx-cache-purge
service).

We have used MediaWiki's file cache[2] until now, but recently the wiki
has been hammered with requests from some stupid Chinese bots/crawlers.

Caching at the web server level is faster as we avoid the PHP overhead
and it seems to make a difference (performance wise), especially when
the bots/crawlers are hitting us.

This is usual done with Varnish[3], but I went with a simple Python
service (30 LOC) for handling the PURGE requests as that is much simpler
thn adding Varnish to our stack.
