Review all custom domains with unusual rDNS entries
Closed, ResolvedPublic

Description

By checking the rDNS entries for resolved IP addresses for custom domains, we can determine whether they directly point to Miraheze cache proxies or not. For example, some wikis use Cloudflare's proxy options, despite telling them in the manual they shouldn't do that.

An automated check was introduced in this commit. Per IRC asking RhinosF1 to review all warnings and criticals:

For each wiki, the actionable (after asking the user with the ability to change DNS records) can be:

  1. Switch the record to CNAME mw-lb.miraheze.org, with the proxy option disabled, or
  2. Set the DNS nameservers to our auth DNS servers, or
  3. If the domain does not longer (indirectly) point to Miraheze: remove the custom domain.

Thanks @Southparkfan,

As discussed on IRC, we'll send 2 notifications within the next 14 days. No response = CD revoked.

I plan to send both on wiki message and email.

Wikis where they don't serve a Miraheze wiki will be removed in the morning. For ones that do, as above crats will have 14 days to make the change.

All not serving Miraheze have been pulled and unset, I will alert crats for them wikis shortly.

Status?

I'm marked as busy (see staffwiki) but any on the list that still trigger icinga alerts can be removed.

rDNS OK - wiki.iufs.jp reverse DNS resolves to cp6.miraheze.org

wiki.titan.land was removed by Paladox already

therefore this task is resolved.
