What 99.9% Uptime Really Means for Your Website
How much downtime does 99.9% uptime allow?
A 99.9% uptime guarantee allows about 43 minutes of downtime per month, or roughly 8 hours and 45 minutes per year. A 99.99% guarantee allows only about 4 minutes per month.
Uptime is the share of time your website is reachable. Nearly every hosting company in Bangladesh and abroad advertises 99.9% uptime, often in large letters next to the price. It sounds close to perfect, but the details behind that number matter more than the number itself.
This guide translates uptime percentages into real minutes, explains what an uptime guarantee usually covers, and shows how to measure it yourself. For the other parts of choosing a plan, see our BDIX hosting price guide.

1. Uptime Percentages in Real Time
| Uptime | Downtime per month | Downtime per year |
|---|---|---|
| 99% | About 7 hours 18 minutes | About 3 days 15 hours |
| 99.5% | About 3 hours 39 minutes | About 1 day 19 hours |
| 99.9% | About 43 minutes | About 8 hours 45 minutes |
| 99.99% | About 4 minutes | About 53 minutes |
Each extra nine cuts allowed downtime by ten times. For an online store, the difference between 99.5% and 99.9% can be several hours of lost orders in a bad month.
2. What an Uptime Guarantee Really Promises
An uptime guarantee is part of a service level agreement (SLA). Read the small print, because it usually works like this:
- It is a credit, not a refund: if uptime falls below the promise, you get a partial credit on your hosting bill, which is usually far smaller than the business you lost.
- Planned maintenance is excluded: scheduled work often does not count as downtime.
- You must claim it: credits are rarely automatic and usually need a ticket within a set time.
- It covers the server, not your site: if a plugin crashes your WordPress site, the server is still up and the guarantee does not apply.
3. Why Downtime Hurts More Than You Think
- Visitors who find your site down often go to a competitor and do not come back.
- Paid ads keep spending money while sending people to an error page.
- Contact forms and orders are lost, often without you knowing.
- Repeated downtime can affect search visibility. Google’s notes on how it handles server errors explain that long-lasting 5xx errors can lead to pages being dropped from the index.
4. How to Monitor Uptime Yourself
- Set up a free uptime monitor that checks your homepage every few minutes and alerts you by email or app.
- Monitor an important inner page too, such as checkout or contact, not only the homepage.
- Keep a simple log of each outage with the time and the host’s explanation.
- Review the log every month. If your host regularly misses its promise, you have evidence to claim credits or move.
5. What Really Keeps a Website Online
- Quality hardware with redundant power and network at the data centre
- A host that does not overload its shared servers
- Updated WordPress core, plugins and themes, so your site does not crash itself
- Security hardening, because hacked sites are often suspended
- Off-site backups, so a failure becomes a short restore rather than a rebuild
Frequently Asked Questions
Is 99.9% uptime good enough?
For most business websites, yes, if the host actually delivers it. Busy online stores and critical services may want 99.95% or better, usually on VPS or cloud hosting.
Can any host guarantee 100% uptime?
No hosting provider can truly guarantee 100%. Hardware fails and updates happen. Treat a 100% promise as marketing and read the SLA terms.
Does BDIX hosting have lower uptime?
Not by nature. Uptime depends on the data centre, hardware and how the provider manages its servers, not on whether it is connected to BDIX.
What should I do when my website goes down?
Check whether it is down for everyone with an online checker, contact your host’s support, and check whether a recent plugin update could be the cause. Note the time for your uptime log.

Final Thoughts on 99.9% Uptime
A 99.9% uptime promise is a reasonable baseline, but it is not a guarantee that your business will stay online.
