How to choose reliable web hosting
Your host decides, more than anything else you control, how often your site is available and how quickly it responds. Marketing pages all promise reliability, so it helps to know what is meaningful. This guide explains what to look for and what to ask, whether you are starting a first site or moving away from a host that keeps letting you down.
Understand the types of hosting
- Shared hosting. Many sites share one server. It is cheap and suitable for small sites, but a busy neighbour can slow yours, and you have less control.
- Virtual private servers (VPS). You get a guaranteed slice of a server. More control and more consistent performance, but you manage more yourself.
- Managed hosting. The provider looks after the software, updates and security for a specific platform such as WordPress. Costs more, saves time.
- Cloud hosting. Resources spread across a provider’s infrastructure and can grow with demand. Flexible, but pricing and set-up can be complex.
The right choice depends on traffic, budget and how much you want to look after. A small brochure site rarely needs more than good shared or managed hosting. A shop that loses money for every minute offline deserves more.
What an uptime guarantee really means
Hosts often advertise 99.9% uptime. That sounds almost perfect, but it allows about 43 minutes of downtime each month and around 8 hours 46 minutes a year, and 99.99% allows under 5 minutes a month. See uptime percentages explained for the full table. Read the fine print:
- What counts as downtime? Planned maintenance is often excluded.
- What is the remedy? Usually a small credit, not compensation for lost sales.
- Who measures it? A promise measured by the host itself is weaker than independent monitoring.
Treat the number as a statement of intent. A better test is how the host behaves when something goes wrong.
Questions worth asking
- How do you handle failures? Ask whether servers are redundant, what happens if hardware dies, and whether sites move automatically.
- How good is support, and when is it available? Look for human support at the hours you need it, not only a chatbot. Test it with a pre-sales question and see how quickly and clearly it is answered.
- Are backups included, and how do I restore them? Daily backups stored away from the server are the minimum. Ask how long a restore takes and whether you can do it yourself.
- Where are the servers? Choosing a location close to most visitors reduces response time. A content delivery network can reduce that effect.
- What are the limits? Ask about caps on visitors, processing time, memory and storage, and what happens when you reach them: slowdown, extra charge or suspension.
- How do renewals and upgrades work? Introductory prices often rise sharply at renewal. Check the long-term cost, not just the first-year price.
- Is there a status page? A host that publishes incidents openly is usually one that takes reliability seriously. See how to use a status page.
Judge it with evidence
Look for independent reviews that describe problems as well as praise, and be cautious of lists that exist mainly to earn referral commissions. After signing up, do not take reliability on trust: set up your own monitoring from outside the host, and use the speed test now and then to see how response times change through the day. A few weeks of data tells you far more than any brochure.
Protect yourself whichever host you pick
- Keep your own copy of backups, not only the host’s.
- Register your domain separately from the host, so you can move without losing control. See domain name expiry.
- Know how to change your DNS records quickly, and keep the time-to-live short before a planned move. See DNS propagation.
- Keep software up to date, because many outages are caused by compromised or outdated sites, not by the host.
Reliability is a combination of the host, your own set-up and how quickly you notice problems. The right host makes the first part easy. Monitoring takes care of the third.
