Although your brick-and-mortar business may have routine 9-to-5 hours of operation, your online presence is open for business 24 hours a day, seven days a week, 365 days a year — or it should be, if you’ve signed up for web hosting with a reliable uptime guarantee.
Business owners in 2024 likely know they need a website. Even if you’re a small operation or only cater to locals, you still need a virtual storefront to bolster the success of your business’s physical location. Having a website means exposure to a broader pool of potential customers or clients; it helps you establish credibility in your field. People trust businesses with an online presence other than a Facebook page and a Yelp listing.
You wouldn’t randomly close your doors during peak business hours, would you? Downtime costs you, so web hosting providers offer uptime guarantees to assure you of their service and reliability.
99.9% Uptime Guarantee (Industry Standard)
Any host worth its salt will offer a minimum uptime guarantee of 99.9%. Anything less is hardly a promise to be proud of, and most of the top shared hosts boast 99.9% uptime rates. This equates to roughly 10 minutes of downtime each week or about 43 minutes in 30 days.
Because of the increased competition at this level of hosting, services with a 99.9% uptime guarantee are extremely affordable. These hosts match the quality and reliability with attractive price tags for the wide range of features that come free of charge.

And here we have the rate hosting experts say to strive for — “five nines or better,” as folks often say. This supreme uptime rate slices the aforementioned downtime rates in half — 30 times over. Few hosts have the chutzpah or the physical infrastructure capacity to pledge this level of availability, but it is most commonly found in dedicated and virtual server plans.

99.9999% Uptime Guarantee (Rare and Really Reliable)
It’s worth noting that uptime guarantees may not include scheduled downtime for maintenance, or there could be other caveats. Even the most reliable hosts may only make this pledge on certain plans, and most providers can only pull it off with strategic datacenter locations.

100% Uptime Guarantee (Best in Class!)
First we have the Holy Grail of uptime guarantees: the 100% availability promise. Only a small faction of web hosting providers will vow to keep your site online at all times or pay the price. This uptime guarantee is almost exclusively limited to dedicated, cloud, and virtual server plans, so you’ll notice price points and resources that match the high reliability.
One of our favorite hosts to recommend for service and support, Liquid Web delivers best-in-class hardware, expert support, and round-the-clock availability monitoring to back the 100% network uptime guarantee. Few hosts have the means to offer such a promise.
Liquid Web’s infrastructure offers custom confirmations, robust security, and meticulous backups conducted by the team.

No Uptime Guarantee: Bluehost
Bluehost is a staple in shared web hosting and regularly delivers the 99.9% uptime rate customers expect from popular hosts, but does not guarantee uptime rates or reliability. While Bluehost promises to try to resolve any issues within 15 minutes, extreme server pains may take longer to relieve.
That would be a major red flag for essentially any other hosting provider. Nevertheless, Bluehost is a trusted partner for millions of individuals, small business owners, and enterprise professionals. The hosting company is endorsed by the WordPress.org team, offers round-the-clock expert support, and is routinely recognized by the shared hosting community. We have no problem suggesting Bluehost as an option, so long as you aren’t expecting to enforce the regular uptime policies found elsewhere.
- Up to unlimited website domain and email hosting
- 1-click WordPress installs and software updates
- Support for popular shopping carts with FREE SSL
- Up to $200 in Microsoft and Google Ad credit
- Industry-leading hardware and uptime rates

Uptime Guarantee Definition & Downtime Calculator
Bringing it back to the basics, uptime is the amount of time your website is online and accessible to the public. Naturally, you want this rate as close to 100% as possible. As such, hosting providers often offer an uptime guarantee to distinguish their service from that of competitors.
An uptime guarantee is your web host’s assurance your site will be online a certain percentage of a year. You can calculate how much cumulative downtime to expect for your site given a certain uptime rate, or see the highlights below. It’s generally understood that 99.9% uptime is a hosting industry standard, whereas five nines or better (99.999% and up) is the ideal.
- 99.9% uptime means your website may be down for a total of eight hours, 45 minutes, and 57 seconds each year.
- 99.99% uptime means your website may be down for a total of 52 minutes and 35.7 seconds each year.
- 99.999% uptime means your website may be down for a total of five minutes and 15.6 seconds each year.
- 99.9999% uptime means your website may be down for a total of 31.56 seconds per year.
- 100% uptime means your website is always online (be sure to read any SLA fine print!).
Some hosts offer a service-level agreement (SLA) with their promise of availability. In short, an SLA commits the host to a refund should a customer experience downtime that exceeds the uptime guarantee. An SLA typically defines a minimum outage period to give the host time to detect the error. Then a host may credit you a certain percentage of your monthly fees for a month in which you experience more downtime than normal.

Consider your web host a silent partner in your business. The team keeps the lights on and helps ensure things run smoothly, but the brand is yours to foster and grow. Review servers and plans from the most reliable hosts of 2024 for more of the best uptime guarantees to get started!
