The availability of a website is measured by the percentage of a year in which the website is publicly accessible and reachable via the Internet. This is different from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it as in the event of a network outage.[citation needed] A hosting provider's Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the systems. This scheduled downtime is often excluded from the SLA timeframe, and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a system drops below that in the signed SLA, a hosting provider often will provide a partial refund for time lost. How downtime is determined changes from provider to provider, therefore reading the SLA is imperative.[11] Not all providers release uptime statistics.[12] Most hosting providers will guarantee at least 99.9% uptime which will allow for 43m of downtime per month, or 8h 45m of downtime per year.

Not all software is specifically supported by name by web hosts, but you can still use it if the requirements are met. You can use the Scripting and Languages filter to find hosts that support the technology that your desired app runs on. Any other questions you may have on how to narrow down your search as you compare web hosting providers, be sure to let us know!

Virtual private server (VPS) or cloud hosting can be a good middle-of-the-road option between the lowest pricing (shared servers) and highest reliability (dedicated servers). A VPS is a physical server that usually has multiple sites hosted on it. However, it’s much more sophisticated than shared servers in its ability to distribute server resources – and it carries a lighter price tag than for dedicated hosting.

Web hosting’s similar. There are expensive options out there that have become popular because their price tags come with names that identify them as the lobsters of web hosting. But some of the lesser-known hosting providers offer much of the functionality of their bigger cousins at much more reasonable prices. Let’s compare the prices of the top 10 web hosts.


You get other customer-centric bonuses for 24/7 customer support, including 24/7 toll-free callback phone support, free domain name and SSL certificates for as long as you remain a MochaHost customer, a website builder with 500 free templates (and a service that will custom-design your site if you need) and a site migration service. In addition, all plans are e-commerce ready and come with free shopping cart software.


And while the free hosts we recommend guarantee you can keep your free hosting as long as you’d like, you will want to take advantage of additional (paid) features as your site grows. Those same providers offer paid plans to upgrade your service, however, serious site owners should strongly consider opting for a reputable, affordable, full-featured hosting provider.
As with backups, SSL certificates are not a necessary feature your web host must offer, this is especially so since companies like Let’s Encrypt offer them for free. However, if you’re looking to streamline the process of getting your site fully equipped and online in no time, the extra convenience of getting this certificate from your web hosting provider is a nice add-on.
