Custom domains

If you host your microblog with a paid plan, consider pointing a custom domain to it. This could be something like microblog.yourdomain.comor even just Mapping a custom domain to is included free, as long as you already have your domain registered.

To get started, update your DNS record to point to Instructions for this will vary depending on your registrar, but all registrars will support 2 standard record types: “A” and “CNAME”.

A record → “”

CNAME record (“www” or “micro”) → “”

More details:

  • If you want to use a subdomain such as or, create a “CNAME” record wherever your domain is registered and use the value “” (replacing “username” with your own username).
  • If you want to use a root domain such as, create an “A” record wherever your domain is registered and use the IP address value: “”.
  • If you want both the root domain and to work, you’ll need both an “A” record for the root domain and a “CNAME” record for the “www” version. Also, enter “” in the settings in (By including “www”, will know to also enable the root domain version.)

After you’ve updated your DNS records, click on Posts → Design in on the web, then scroll down to the custom domain name field. Fill in the hostname (e.g. that you’d like to use for your site.

HTTPS can also be enabled for any custom domain. We set this up for you, but it may take up to a day for it to be ready. Please email with your custom domain if HTTPS still hasn’t been enabled.

If you need to register a new domain name, we also offer domain name registration on

Changing your Domain

As well as adding a custom domain from to, you can change to in the future. When adding a custom domain for the first time, or changing to a new one, various things may appear broken for a while:

  • None of your images will load
  • HTTPS won’t initially be enabled, so visiting your site may show an “insecure message”

Both of these are normal. Behind the scenes, we’re automatically setting everything up. Things should clear up in about 48 hours.

I see that my the CNAMEs I set up a few years ago uses instead of, is that wrong and should be changed?

No, that’s fine too. It can be

With regards to setting up the option as opposed to just the root, is there a reason why you’d want (or need) to do this?

Every time I have come across this in documentation I have come to a conclusion of “whatever.” I went with Technically you can setup both as far as destinations, but are people still typing www?

That’s exactly it, I can’t recall the last time I typed in www. It seems archaic to me, so I’ll probably not bother setting it up. Thanks @Moondeer !

On Changing Custom Domains:

Thanks for info that domain changes take 48h to propogate correctly.
I suspect most of the time would be spent making external changes aroudn it.
Has anyone been through the process and have any wise words about what a checklist might look like to get this fully right?
Here’s my quick ideas:

  • redirecting old posts. Do all url slugs stay the same : i.e. would I be safe to pattern redirect like old.domain/2021/04/16/post-name.html to new.domain/2021/04/16/post-name.html
  • Cross posting & feeds. Relist all feeds in Would folks RSS’d to you drop I’m guessing? (p.s. this seems like a major vulnerability with building a following of RSS subscribers, you’d have to give them lots of warning to re-sub)

Anything major I’m missing here?
