You Should Run a Certificate Transparency Log

  Servers: one. No need to make the log a distributed system, CT itself is a distributed system. The uptime target is 99%3 over three months, which allows for nearly 22h of downtime. That’s more than three motherboard failures per month. CPU and memory: whatever, as long as it’s ECC memory. Four cores and 2 GB will do. Bandwidth: 2 – 3 Gbps outbound. 3 – 5 TB of usable redundant filesystem space on SSD or 3 – 5 TB of S3-compatible object storage, and 200 GB of cache on SSD. People: at least two. The Google policy requires two contacts, and generally who wants to carry a pager alone.

  Seems beyond you typical homelab self hoster, except for the countries that have 5gbps symmetric home broadband.
  If anyone can sneak 2-3gbps outbound pass their employer, I imagine the rest is trivial.
  Altho… “At least 2 [people]” isn’t the typical self hosting

    Yup…

    Uptime is fine, CPU/men is fine. I’d even be fine with grabbing a few ssd’s for the task…

    But 2-3gbps is a non-starter, not to mention 2 contacts.

    I mean, the very first few lines make it pretty clear he’s not writing for the typical homelab self hoster:

    If you are an organization with some spare storage and bandwidth, or an engineer looking to justify an overprovisioned homelab, you should consider running a Certificate Transparency log.

    But your endpoints are already available to everyone with just a nslookup.

    Maybe it’s more the permanent history of that, so if you run something like “radarr.example.com” then you wouldn’t have plausible deniability if you’re sued and the CT logs are presented as proof of your wrongdoing

      Not if you use wildcard dns records.

      With Encrypted Client Hello you can have some more privacy on obtaining certificates for wildcard domains, IIRC.

      Not if you run a wildcard CNAME for your sub domains right ?
      Like I have *.mydomain.com point to my server, and there I have a different reverse proxy depending on the domain.

  I guess this is mainly targeted at Universities and organisations that mirror repos?

  They’re the kinda place (I presume) that would be able to support this…
