(Filing per email request. :)
I was looking for info about https://mirrors.wikimedia.org/ the other day, but couldn't find anything beyond the very brief mentions in the 2 pages on wikitech about Sodium and HTTPS/Domains.
I'd suggest a basic addition (either to the index.html or to a new wikitech page) that lists:
- Who maintains it - (Ops)
- Why we maintain it - (IIUC, it's just an altruistic and low-effort/low-resource public service, giving back to the FLOSS community, but was initially internal-only)
- Where the servers are located - (Virginia) - so that people know whether it's a close-proximity server for them to use.
- Links to https://www.debian.org/mirror/sponsors and https://launchpad.net/ubuntu/+mirror/wikimedia-archive as easy confirmation that it's official
