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.
Usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some ISPs actively attempt to block home servers by disallowing incoming requests to TCP port 80 of the user's connection and by refusing to provide static IP addresses. A common way to attain a reliable DNS host name is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.[10]
WordPress is one of the most popular content management systems (CMS) in the world, and as such, many web hosting providers offer options that cater to this rather large niche. You can certainly host your WordPress site on a standard shared hosting plan, but by choosing a WordPress-specific option, you'll spend less time configuring and managing your WordPress installation.
In terms of what many vendors call unlimited service, Web Hosting Pad's terms of service indicate that their definition of unlimited is what they call "incremental." Basically, as you need more capability, they want to discuss that with you, both to help you get the most out of their services, and to make sure you're using their systems without abusing them.
On the plus side, SiteGround offers free automatic daily backups, access to the Cloudflare CDN, high-performance SSDs for all plans, unlimited email accounts, and integration of the free LetsEncrypt SSL certificate into sites. The company does limit bandwidth and storage, but even those who claim to offer so-called unlimited bandwidth and storage really have some limits in their terms of service.
Established back in 1998, LunarPages operates three state-of-the-art data centers. Equipped with multiple GigE fiber connections to the internet backbone, the company built out seismically-braced racks and cabinets, fully-redundant Liebert HVAC cooling systems, a diesel generator that can run for weeks, and a pre-action dry pipe fire suppression system.
Because web hosting services host websites belonging to their customers, online security is an important concern. When a customer agrees to use a web hosting service, they are relinquishing control of the security of their site to the company that is hosting the site. The level of security that a web hosting service offers is extremely important to a prospective customer and can be a major consideration when considering which provider a customer may choose.[13]
For example, you may certainly contact your host at any time, but when are they available to respond to your questions and concerns? How long will it take for someone to get back to you? Will there be someone to help you if your mission-critical website goes down at 3:00 in the morning? What language(s) do your host providers speak? Support in Malagasy is probably essential if you live and work in Madagascar, but fairly useless if you are in North America.
Sadly, there is a bit of a "gotcha" to the free automatic backup service. If you're paying $3.95 a month (for the first year of hosting, then $9.95 a month), you don't get restores for free. Each restore, no matter how small or large, will cost you $19.95. I'm not sure how I feel about that. On the one hand, the company has to pay salaries to tech support reps who can handle panicking customers. On the other hand, it seems kind of mean-spirited to hit someone when they're down with an added fee. That said, getting your data back – at any price – is priceless.
GlowHost picked up major points for their 91-day money-back guarantee. They were six days short of DreamHost's 97-day guarantee, but with these numbers, who's quibbling over a few days? The company also picked up points for their 24/7/365 phone support option and free cPanel offering for most plans. The company operates 18 datacenters worldwide. Finally, the company gains major points by driving all its hosting services with wind power.

Because we offer what is known as a shared architecture, our customers share both the hardware and the "pipes" we use to transmit data across the web, so we do monitor bandwidth to ensure optimum performance for our customers. Again, we are able to support more than 99.5% of customers with no issues at all. However, in some wonderful cases, customers become so successful that their traffic and data transfer outgrow our shared architecture. When that happens, we work with the customer to identify scalable solutions, such as our Virtual Private Servers.
You can also host your website on WordPress.com, but that's different from the kind of hosting mentioned above. WordPress.com uses the same code from WordPress.org, but it hides the server code and handles the hosting for you. In that sense, it resembles entries in our online site builder roundup. It's a simpler but less flexible and customizable way to approach WordPress hosting. It's definitely easier, but if you want to tinker and adjust and optimize every aspect of your site, it might not be for you.
Until 1991, the Internet was restricted to use only ...for research and education in the sciences and engineering...[1][2] and was used for email, telnet, FTP and USENET traffic - but only a tiny number of web pages. The World Wide Web protocols had only just been written[3][4] and not until the end of 1993 would there be a graphical web browser for Mac or Windows computers.[5] Even after there was some opening up of internet access, the situation was confused until 1995.[6]
The company got bonus points for its policy of performing regular daily backups, even on the lowest-priced shared hosting accounts. It lost points because its promotional price on the low-cost shared hosting does go up after the promotional period. That said, Bluehost also gained points for offering 24-7 phone support and SSH access for certain plans.
