Web hosting and email: host and provider responsibilities

Who is responsible for what: hosts, hosting providers, responsibility and policy

Hosting is the computer your website’s files actually live on, rented from a company that keeps it switched on, connected and, on some plans, maintained. Without it a domain name has nowhere to point, and a finished website is a folder on someone’s laptop. The single distinction worth carrying into every page in this section is that a host is responsible for the machine, and you — or whoever maintains your site — are responsible for the software running on it. A host with a flawless uptime record will not stop an out-of-date plugin being compromised, and a security incident is not evidence that the hosting itself was bad. That boundary is the reason security and maintenance are separate sections rather than folded into this one, and it is worth reading what web hosting actually is first if any of this vocabulary is unfamiliar.

What hosting does to page speed specifically is a different, already-answered question: see why websites are slow and does Australian hosting make a site faster for that half of it.

What’s here: shared, VPS and managed hosting, standard inclusions and choosing a host, general to specific

What web hosting actually is — the basic vocabulary, for anyone starting from nothing.

Shared hosting versus VPS versus managed hosting — different answers to “who else is on this server, and who is responsible when something breaks.”

Choosing a host, and what a reseller arrangement means for you — the handful of questions that actually predict a good relationship with a host, and what buying through a reseller changes.

What a hosting bill covers and what it does not — storage, bandwidth, a control panel, backups, support — read against what a plan’s marketing page implies rather than states.

Australian hosting and data residency — where your customers’ data actually sits, and the privacy obligations that follow from it.

Does Australian hosting make a site faster — when server location is a genuine business decision and when it is a marketing line.

Content delivery networks explained — whether a CDN is bundled into your hosting plan, or something to buy separately.

Uptime, downtime and what a guarantee actually promises — what “99.9%” still permits, and what actually matters when it is not met.

Backups: who takes them and where they live — a host’s included backup and a genuinely reliable one are not automatically the same thing.

Business email on your own domain — why a free consumer email address undermines a business’s own website in a way most owners never connect to the site itself.

Certificates, and what a padlock proves — what SSL/TLS actually certifies, and why “does it have SSL” is close to a meaningless question now.

Who holds the hosting account — the account that can take a whole site offline in one cancellation, and who currently controls it.

Green hosting and the carbon question — what a “green” hosting claim actually verifies, and what it does not.

Moving hosts without downtime — the sequence that keeps a site and its email running through a migration, and the two mistakes that take it down anyway.

A note on hosting price, provider responsibilities and hosting services

Hosting is quoted in every currency and every billing cycle a market will bear, and a genuine comparison needs the plan’s inclusions in front of you, not just its monthly figure. A provider’s own policy on what its plan covers — support hours, backup frequency, the general responsibilities it accepts versus the ones it leaves with you — is usually more informative than the headline price. Where a figure is quoted, ask whether it is inclusive or exclusive of GST — see GST on web design for why that question changes the number by ten per cent either way. What hosting actually contributes to an overall build quote is set out on web development services. For where hosting sits inside web design as a discipline, start with web design in Australia.
