Every host advertises 99.9% uptime. It sounds like perfection, but the missing 0.1% is a real number — and for a business, that number is money. Here it is in hours.
The maths
- 99% is about 3 days and 15 hours of downtime a year.
- 99.9% is about 8 hours and 45 minutes a year.
- 99.99% is about 52 minutes a year.
Each extra nine cuts downtime roughly tenfold. The jump from 99% to 99.9% is the one most businesses feel.
Why the hours matter
When a site is down, three things happen at once. You lose the sales in that window. Search engines that crawl a dead page can quietly lower your ranking. And people who hit an error rarely come back — they go to a competitor.
Downtime is not just lost minutes. It is lost sales, lost ranking and lost trust — and trust is the slowest to rebuild.
How we hold it
Uptime is not luck. It comes from monitoring that alerts us before customers notice, a CDN close to your visitors, backups so recovery is fast, and caching that holds under a spike. We watch so you do not have to. Talk to us about hosting that stays up.
