Hosting Glossary
What is TTL?
What TTL actually means, minus the jargon — with the example that makes it obvious.
The short answer
TTL is how long DNS resolvers may cache a record's answer before asking again — the setting that determines how fast your changes reach the world.
The sections below unpack it properly — how it works, why a site owner should care, and a concrete example of it in the wild.

To read, obviously
Long TTLs (hours) reduce lookup load and add resilience; short TTLs (minutes) make changes propagate quickly. The catch: the TTL that governs a change is the one that was set before it.
Hence the migration ritual — lower TTLs a day ahead, make the change, restore long TTLs after; propagation then runs on your schedule instead of yesterday's.
A picture that makes TTL stick
The expiry date on cached directory copies — everyone keeps using their copy until its date passes; printing new directories today doesn't recall the old ones already distributed.
Analogies simplify, of course — but this one holds up well enough to reason with, and reasoning is the point of a glossary.
Why you should care
TTL literacy converts DNS changes from anxiety into scheduling — planned moves become minutes of transition, and 'propagation is slow' becomes a variable you set rather than weather you endure.
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.
A concrete example
Before a host migration, an admin drops the A record's TTL from 4 hours to 5 minutes; on switch night the world follows within minutes, and the TTL returns to hours afterwards.
Ordinary, once seen — which is the point: most hosting concepts are simple machinery wearing intimidating names.
Where you'll meet it on our platform
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 DNS, DNS Propagation, A Record and Nameserver.
Support is answered by real people around the clock — including the questions other hosts call out of scope.
Jargon is a service failure
We think unexplained jargon is a service failure — this glossary is the support desk's accumulated translations, published where the search engines can hand them out.
Renewal prices match signup prices, so the year-two invoice is the most boring email you'll get from us.

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.
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.
One term, fully landed
TTL defined, pictured by analogy and placed in your own control panel — recognise-level in a single read.
Analogies that stick
Each concept gets a picture you'll remember at the moment you actually need it.
The practical stakes named
Not just what it is — when it's the answer to a problem you're having.
Getting Started
How to get going
- 1
Spot it in your own setup
Open your control panel and find where this concept lives — seeing it attached to your own site is what converts definition into understanding.
- 2
Check the defaults
Our platform ships sane defaults for this — verify rather than assume, and you'll know your setup instead of hoping about it.

Follow the related terms
Concepts travel in packs — DNS, DNS Propagation and A Record complete this one's picture, and each is a two-minute read away.

FAQ
Your questions, answered
What TTL should my records use?
Stable records: an hour to four hours (resilience and cache efficiency). Records you expect to change, or during any planned migration: five minutes temporarily. Permanent very-short TTLs just tax resolvers for flexibility you rarely use.
I lowered the TTL but the change is still slow — why?
The lowering itself obeys the old TTL — resolvers holding the record with 4 hours remaining won't see your 5-minute setting until they refresh. Lower it at least one old-TTL-period before the actual change.
Do you include email with hosting?
Yes — mailboxes on your own domain come with every hosting plan, with webmail, IMAP/POP/SMTP access and spam filtering. Standalone email hosting also exists for domains whose websites live elsewhere.
Can I choose my PHP version?
Yes — PHP versions are selectable per site from the control panel, so a legacy application and a current one can live side by side. Extensions and per-site settings are adjustable in the same place, no support ticket needed.
Do you support staging sites?
Yes — plans with staging let you clone the live site, test changes safely, and push to production when ready. It's the difference between 'I hope this update works' and knowing it does.
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.
What happens if I outgrow my plan?
You upgrade in place — plan changes apply from your client area without migrations or downtime, and our range runs from small shared plans through VPS to dedicated servers, so growth is an account change rather than a new-host project.
Keep exploring
Nameserver
Nameservers are the servers authorised to answer DNS queries for your domain.
A Record
An A record maps a hostname directly to an IPv4 address — the DNS entry that tells browsers which server actually holds your website.
Secure Hosting
Imunify360, isolation and hardened defaults for security-first sites.
Email Hosting
Professional mailboxes on your own domain at a flat, honest price.
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.
