Pointed here. Still yours.
'TLS certificates' and 'DNS management' are two lines on every rate card. This page is the rest of it: who owns which piece, what happens to your mail records, how long the propagation window actually runs, and what it costs to change something later.
Who owns what
Three things get discussed whenever a domain is on the table. Only one of them is ours.
- You
The domain name itself
Registered in your name, at whichever registrar you chose, renewed on whatever cycle you set up there. That relationship never moves to us.
- CustomHosted
The DNS zone and its records
Once a domain points here, the records inside it are kept correct as the platform changes underneath — added, updated, and audited without a spreadsheet only one person remembers how to edit.
- CustomHosted
The TLS certificate
Issued before the cutover and renewed ahead of every expiry, on a standing schedule — see the lifecycle below.
Two ways to point a domain
Most accounts pick the first. The second is a real, supported path, not a workaround.
Delegate the nameservers
- You change
- One setting at your registrar — the nameservers, pointed at ours.
- We manage after
- Every record underneath from that point on: the zone lives here, changes are made here, and nothing needs a second login to keep in sync.
- Right call when
- Most accounts. It's the simplest path once you've decided a domain lives here.
Keep DNS where it is
- You change
- Add the specific records we ask for at whichever DNS provider you already use.
- We manage after
- Only what those records point at — the zone itself, and everything else in it, stays under whoever already runs your DNS.
- Right call when
- You run DNS for other domains from one place already, or a records-only handoff was part of the deal your registrar or IT team already has in place.
The record sheet
Every record class on a typical account. The "carried over, untouched" rows are the direct answer to the question this page exists to answer: your mail does not move.
| Record | Purpose | Handling | Detail |
|---|---|---|---|
| A / AAAA (apex) | Points your root domain at the edge network. | Managed for you | Kept correct as the platform changes underneath it — you never hand-edit this. |
| CNAME (subdomains) | Points a subdomain — www, an app, a staging environment — at the platform. | Managed for you | Added as part of onboarding, and again any time a new subdomain is requested. |
| NS (nameservers) | Names whose DNS is authoritative for your domain. | Managed for you | Only touched at all if you choose full delegation above — everything under it is then ours to keep correct. |
| CAA | Names which certificate authority is allowed to issue for your domain. | Managed for you | Set to match whichever authority actually issues your certificate, so an unauthorised issuance request has nothing to succeed against. |
| MX | Routes mail addressed to your domain to your mail provider. | Carried over, untouched | Copied across exactly as they stood at your previous DNS host. Your mail keeps working without a second look. |
| TXT — SPF, DKIM, DMARC | Proves to receiving mail servers that a message genuinely came from your mail provider. | Carried over, untouched | Moved verbatim alongside the MX records above — nothing here is regenerated, reordered, or dropped. |
| TXT — domain verification | Proves ownership of the domain to a third-party tool that asked for it. | Carried over, untouched | So a search-console, analytics, or single-sign-on integration you'd already verified doesn't need re-verifying after the move. |
The certificate lifecycle
Issued ahead of the cutover, renewed ahead of every expiry, and escalated to a human the moment either step doesn't go as planned.
- 1
Issued before the cutover
A certificate is requested and issued ahead of the switch, so HTTPS is already live the moment traffic moves — not something set up afterward once someone notices it's missing.
- 2
Renewed ahead of expiry
Renewal runs on a standing schedule, well before the expiry date — the same watch signal /monitoring lists under certificates.
- 3
HTTPS by default
Every property gets one, apex and www alike. There is no unencrypted version of the site actually reachable.
- 4
Apex, www, and the http:// redirect
Whichever of the apex or www variant isn't your canonical address forwards to the one that is, and the plain http:// address forwards to https:// — both on by default.
- 5
If a renewal ever fails
Escalated straight to a human rather than left to lapse quietly — the same rule the rest of the watch list follows for anything that doesn't fix itself.
The propagation window
What actually happens between "point the domain here" and "it's live" — and what rolling it back looks like. See Migrations for the cutover in full and Onboarding for where it sits in the first week.
- 1
TTLs lowered ahead of time
Shortens how long resolvers hold onto the old answer, before anything about the records themselves actually changes.
- 2
Rehearsed against the standing copy
Checked against a working copy of the site or app first — the switch itself isn't the first time it's been tried.
- 3
The old host keeps serving through the window
Nothing is torn down until traffic has actually moved — a visitor whose resolver is slow to catch up still reaches a working site, just from wherever it was before.
- 4
Rollback is the same move, reversed
Pointing the records back is not a special procedure — it is this same change, run the other direction, on the same propagation timeline.
Changing something later
A record is an ops request. A redirect map, a new route, or a canonical tag is application routing — a code change, so it goes through the loop instead.
| Request | Who | How it's asked for | Cost |
|---|---|---|---|
| Add a subdomain | CustomHosted | Send it through the same quote channel as any other request. | No charge — DNS management is part of every plan. |
| Point a second domain at a new site | CustomHosted | Briefed the same way, naming the new domain and which site it should serve. | Additional static site, another site on the same account, same edge network. |
| Move mail providers | CustomHosted | Tell us the new MX, SPF, DKIM, and DMARC records your new provider gives you. | No charge — this is still a DNS record change. |
| Verify a third-party service | CustomHosted | Send the verification record the third party asks for. | No charge — this is still a DNS record change. |
| Add a redirect map, a new route, or a canonical tag | CodeHerder | Briefed like any other change — this is what the Agentic iteration — CodeHerder add-on covers. | Priced as a briefed change, not a record: this is application routing, not DNS, so it's briefed, an agent opens the pull request, a human merges it, and the same pipeline redeploys — the full rule set, cache behaviour, and header story lives on Delivery. |
The full rule set behind the redirect row above — every URL rule, the cache, and the response headers — is on Delivery. Read how a change gets briefed in the first place on Brief a change, and how it ships on The Loop.
The honest limits
Not buried in a footnote — the same discipline as every other honesty band on this site.
We're not a registrar
Registration and its renewal stay between you and whoever you registered the domain with. No record we manage can save a domain that lapses at the registrar.
We route mail, we don't run mailboxes
Mail records are pointed at whatever provider you use and carried over untouched. Hosting the inboxes themselves is a separate service we do not provide.
DNS-level geo-routing or traffic-splitting is a custom quote
Standard plans point a domain at one place. Splitting traffic by region or condition at the DNS layer is a real thing we can build — just not something a standard plan includes by default.
Propagation depends on resolvers nobody controls
Lowering TTLs ahead of a change shrinks the window, but a resolver that ignores TTLs and caches longer than asked is outside anyone's control, ours included.
Transfer locks and auth codes live at your registrar
Moving a domain to a different registrar entirely needs a code only your registrar can issue — that step never runs through us.
Domain questions
The follow-ups that come up once "DNS management" stops being a line on a rate card and starts being something a real cutover depends on.
01Will my email break when my domain points here?
No, for mail addressed to your domain: your MX records and the TXT records behind SPF, DKIM, and DMARC are carried over exactly as they stood at your previous DNS host — see the record sheet above. That is the inbound half. If your app also sends mail outward — a password reset, a receipt — see Email for the records that add alongside these, untouched.
02How long does the propagation window take?
It depends on resolvers we don't control, so there's no fixed figure to promise. What we do control: TTLs are lowered ahead of the switch to shrink the window, the change is rehearsed against a standing copy first, and the old host keeps serving until traffic has actually moved.
03Do I lose control of my domain?
No. Registration and its renewal stay yours at your registrar the whole time — see the ownership table above. What moves to us is the zone underneath it and the certificate, and reverting either is the same change run in the other direction.
04Can I keep DNS somewhere else instead of delegating?
Yes — add the specific records we ask for at whichever DNS provider you already use, rather than pointing the nameservers here. You keep running DNS; we manage only what those records point at.
05What happens if a certificate renewal fails?
It's escalated straight to a human rather than left to lapse quietly. Renewal itself starts well ahead of the expiry date specifically so there's room to catch a failure before it becomes visible.
06Can you split traffic by region at the DNS level?
Not as part of a standard plan — DNS-level geo-routing or traffic-splitting is a custom quote. A standard plan points your domain at one place.
07What does adding a subdomain or a second domain cost?
A subdomain is a DNS record change, so it costs nothing extra — DNS management is part of every plan. Pointing a whole second domain at a new site is priced as additional static site, another site on the same account, same edge network.
08What about a redirect map or a canonical URL change?
That's application routing, not a DNS record, so it goes through the same loop as any other code change: briefed under the Agentic iteration — CodeHerder add-on, an agent opens the pull request, a human merges it, and the same pipeline redeploys. See Delivery for the full rule set — every URL rule, the cache, and the response headers.
09Who'd be doing this if I ran DNS and certificates myself?
You would. The hours ledger prices "renewing tls certificates" at around 0.5 hours per certificate renewal — here, that row moves to us as part of every plan.
