Hosting Glossary
What is Uptime?
What Uptime actually means, minus the jargon — with the example that makes it obvious.
The short answer
Uptime is the percentage of time a hosting service is reachable — with each additional nine dramatically shrinking the allowed downtime.
Below: the fuller explanation, an analogy that makes it stick, why it matters in practice, and where you'll actually meet it.

Humans if you're stuck
The arithmetic gives the percentages meaning: 99.9% permits about 43 minutes down per month; 99.99% permits four. Guarantees typically credit fees when breached rather than promising perfection.
Measurement honesty matters — scheduled maintenance, monitoring interval and where the check runs from all shape the number a host claims.
Uptime, by analogy
A shop's opening reliability — 99.9% is the shopkeeper missing three-quarters of an hour a month; the sign says open, and very occasionally it lies.
Hold onto that picture and most of the documentation you'll ever read about it becomes considerably less mysterious.
The practical stakes
Downtime costs trust before it costs revenue — visitors rarely retry, and search crawlers remember absences; the uptime figure is the quiet foundation under every other metric you optimise.
You don't need to operate this layer daily — you need to recognise it when it's the explanation for something, which is exactly when this page pays for itself.
Uptime in the wild
An uptime monitor pings a store every minute from outside; a 99.9% month means its 43,200 checks failed at most 43 times — and the alert emails explain exactly when.
Multiply that example across every site on the internet and you have the concept's entire job description.
How this shows up in your hosting
You'll meet it in the control panel and occasionally in a support conversation — usually already configured the right way. If this term made sense, the natural next reads are Web Hosting, Dedicated Server, Backup and CDN.
Every plan includes free SSL that renews itself, so the padlock is never your job.
Why we wrote a hundred definitions
Every confusing term in hosting eventually becomes a support ticket — so we defined the hundred most common ones properly, once, in the plain English we'd use on the phone.
Our team migrates existing sites free of charge, typically within 24 hours and with zero downtime.

Why HostingAlly
Every plan includes this, whatever you pay
Honest about what you can skip
Most terms are recognise-level, not operate-level — the glossary says which is which.
The next reads, mapped
This entry connects to Web Hosting and Dedicated Server — concepts travel in packs, and the pack is linked.
Grounded in a real platform
Examples reference the hosting you'd actually use, not abstract diagrams.
The practical stakes named
Not just what it is — when it's the answer to a problem you're having.
Linked, not siloed
Related terms cross-reference, so one lookup becomes a working understanding.
Plain English first
Every term defined for site owners, not for other sysadmins — jargon translated, not restated.

FAQ
Your questions, answered
Is 100% uptime possible?
Over short windows, routinely; as a standing promise, no — maintenance, networks and entropy exist. Distrust 100% guarantees; trust transparent measurement, credits with teeth, and a status page that admits history.
How do I verify my host's uptime claims?
Independent monitoring — a free external service checking every minute builds your own record. Data beats dashboards: your monitor's history is the number that reflects your visitors' actual experience.
What does your 24/7 support actually cover?
Real people at every hour, and a scope that includes the practical questions — email setup, DNS, WordPress issues, restores — not just 'the server is up, ticket closed'. Pre-sales questions are welcome too; ask us something difficult and judge the reply.
Is SSL really included at no cost?
On every plan, with no exceptions — certificates are issued automatically when your domain points to us and renew themselves before expiry. The encryption is identical to paid DV certificates; paid tiers exist only for wildcard convenience or organisation-level validation.
Can I transfer a domain I already own?
Yes — transfers in are routine: unlock the domain at the current registrar, grab the auth code, and start the transfer from your client area. The remaining registration time carries over, and DNS keeps working throughout.
Are backups included, and can I restore them myself?
Daily automatic backups are standard, restorable from the panel in minutes — files, databases or both, at 3am without a ticket if that's when you need it. For extra cover, you're welcome to run your own offsite copies alongside.
Where are your servers located?
Our hosting infrastructure runs from European datacentres with London at the core, behind server-level caching that keeps cached pages fast worldwide. For most sites, platform quality — NVMe storage, LiteSpeed, sensible server density — matters far more than the datacentre's postcode.

Web Hosting
Web hosting is the service of storing a website's files on an always-on server and delivering them to anyone who visits its address.

A dedicated server is an entire physical machine rented to one customer — every core, byte and disk answering to a single tenant.
WordPress Hosting
Managed WordPress with LiteSpeed caching, staging and automatic backups.
Drupal Hosting
Drupal hosting with Composer, Drush and per-site PHP control.
Planning to switch hosts? Grab the checklist here.
The steps that keep a site migration dull rather than dramatic: what to back up first, how to shift email across without losing a single message, when to touch DNS, and the two mistakes behind nearly every hour of downtime we come across.
Get online without the games.
Free SSL, free migration, honest renewals and 24/7 human support. That's the whole pitch.
