What is Uptime?
What Uptime actually means, buzzwords removed — with the example that makes it land.
The short answer
Uptime is the proportion of time your hosting is genuinely reachable, and each extra nine on that figure cuts the downtime you are expected to accept.
What follows: the longer explanation, a picture that holds, the practical stakes, and the places you will genuinely meet it.

People, if you get stuck
Turn the percentages into minutes and they stop being abstract: 99.9% permits around 43 minutes offline a month and 99.99% about four. What a guarantee normally promises is a pro-rated credit for a missed target, rather than a claim that nothing can ever fail.
The measurement method shapes that headline figure every bit as much as the engineering does. Whether planned maintenance is excluded, how often the probe runs and where it runs from all feed the figure a host prints on the page.
Uptime, by way of an analogy
Treat it as an engine availability rating. At 99.9% the thing stops for about three quarters of an hour a month without warning: faultless the rest of the time, and dead at the least convenient moment now and then.
Carry that picture with you and most documentation on the topic loses its mystery on a first read.
What genuinely rides on it
Downtime costs trust before it costs money. A visitor who meets a dead site rarely tries again, and crawlers keep a note of every failed fetch. Underneath every other metric you work on, uptime is the quiet floor.
Nobody expects you to work at this layer daily. The aim is recognising it when it explains something — and that moment is exactly when this page pays for itself.
Uptime out in the open
An independent monitor checks a shopfront every minute from outside our network. A 99.9% month means no more than 43 of its 43,200 checks came back bad, and every failure carries a timestamp.
Scale that example across every website online and you have described the whole job of the concept in one stroke.
Where it sits inside your own account
You will meet it in the control panel and now and then in a support thread, usually already set correctly. If this one landed, the natural follow-ups are Web Hosting, Dedicated Server, Backup and CDN.
A free SSL certificate comes with every plan and reissues itself before the old one lapses — the padlock is never yours to diarise.
Why a hundred definitions were worth the writing
An unexplained piece of jargon is, to us, a service defect. This is the support team's collected translations, published where a search engine can hand them over on our behalf.
Hosted somewhere else already? We move the whole site at no charge, usually within 24 hours, and it goes on answering visitors throughout.

Why Hosting & Domains
Standard on every plan
Clear about how deep to go
Most of these are recognise-level rather than operate-level, and every entry says which it is.
The next step, drawn out
Carry on into Web Hosting and Dedicated Server — ideas rarely travel alone, so the neighbours are linked in.
Tied to real hosting
Examples name platforms you would genuinely use, never an abstract diagram on a whiteboard.
Stakes made explicit
More than what a thing is: the moments it turns out to be the answer to a problem you have.
Cross-wired entries
Related terms point at each other, so one lookup compounds into working knowledge.
Jargon-free by design
Definitions written for people who run sites, not for other sysadmins — translation rather than restatement.

Frequently Asked
The questions that come up most
Can anybody genuinely deliver 100% uptime?
For a short spell, often. As a standing promise, never, because maintenance, network faults and ordinary entropy rule it out. Be wary of anyone advertising 100%, and look instead for open measurement, credits that genuinely cost the provider, and a status page whose history is still visible.
How do I verify a host's uptime claims myself?
Aim an external monitoring service at your own domain. Probing every minute, a free checker builds a record nobody but you controls. That log beats any provider dashboard, since it records what your visitors were actually served.
What does round-the-clock support actually cover?
A reply from a person at any hour, covering the practical jobs: setting up a mailbox, a DNS record, a WordPress fault, a restore. Not 'server is up, closing ticket'. Put a hard question to us before you buy — the answer is a fair sample of what follows.
Is the free SSL certificate genuinely free?
Entirely, on every plan. The certificate is issued as soon as the name points here and reissues itself well before it lapses. On encryption it matches any paid DV certificate — the paid options exist for wildcard coverage or organisation validation, which most sites never need.
