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.
Mailboxes and email storage offered by web hosts give you professional email addresses with your website’s domain name. Ideally, a web host will offer unlimited mailboxes so you can give each of your employees an individual email address and have room to grow.

The first thing that caught our eye about Complete Internet Hosting was a great answer to my biggest complaint about hosting providers. Most hosting providers will suck you in with a relatively aggressive starting price, but when it comes time to renew, the renewal price can be two or three times the original price. I've even found one company that renews at more than six times the original price.

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]


Hosting that is aimed at specific CMS platforms and tweaked optimally for them: e.g., WordPress hosting, Drupal hosting, Magento hosting, etc. In these cases, the best hosts do far more than just provide the minimal requirements for those platforms. They provide a rich, and fully managed environment so your site can perform like a well-tuned machine.
Do you recommend any of those for “testing purposes”? I am looking for a free hosting with a CPanel and easy WordPress installation and management; I fully understand that a testing website is not the same as a productive one but since it would up to the customer to find the best hosting to migrate (though I am helping a little bit on that project) and for my testing purposes paying is not precisely an option since none of those sites is where they would host their site at the end; I am looking for something free but that is good enough for me to work and test and to give a final demo to my customer

This is unfortunate because, these days, owning a website is becoming a crucial part of running a successful business, and more and more folks are establishing a web presence for their personal brand as well. You can use hosting to sell online, store and share your portfolio, or even publish your freelance writing samples and resumé. Yet, even the basics — What is web hosting? — can be lost on the average web user.

Similar to the dedicated web hosting service, but the user owns the colo server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and expensive type of web hosting service. In most cases, the colocation provider may provide little to no support directly for their client's machine, providing only the electrical, Internet access, and storage facilities for the server. In most cases for colo, the client would have his own administrator visit the data center on site to do any hardware upgrades or changes. Formerly, many colocation providers would accept any system configuration for hosting, even ones housed in desktop-style minitower cases, but most hosts now require rack mount enclosures and standard system configurations.

If you're planning on selling a product, look for a web host that offers a Secure Sockets Layer (SSL) certificate, because it encrypts the data between the customer's browser and web host to safeguard purchasing information. You're probably familiar with SSL; it's the green padlock that appears in your web browser's address bar as you visit an online financial institution or retail outlet. A few companies toss in a SSL certificate free of charge; others may charge you roughly $100 per year for that extra security layer.
