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.

Note: The dual meanings "host"/"guest" of Latin hospes and its progeny are due to customs of reciprocity: a person serving as guest on one occasion would act—and be expected to act—as host on another occasion to a visiting former host. Both Latin hospes and Slavic gospodĭ have undergone a considerable degree of phonetic reduction from their putative etymons—in particular in the Slavic case, where Latin unstressed syllable reduction and syncope were not at play—leading some to question the correctness of the etymologies. Parallel compounds with the same second element are Greek despótēs "master, lord" (going back to *dems-pot- "master of the house"; see despot), Sanskrit dámpatiḥ "householder, lord of the house," Avestan də̄ṇg paitiš; Sanskrit viśpátiḥ "chief of a settlement/tribe," Avestan vīspaitiš, Lithuanian viẽšpats "lord" (with outcomes of Indo-European *u̯iḱ-, *u̯oiḱ- "house, community"; see vicinity).
The host may also provide an interface or control panel for managing the Web server and installing scripts, as well as other modules and service applications like e-mail. A web server that does not use a control panel for managing the hosting account, is often referred to as a "headless" server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.). 

Having multiple servers hosting the same content for better resource utilization. Clustered servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Usually web hosts use clustered hosting for their shared hosting plans, as there are multiple benefits to the mass managing of clients).[9]
1250–1300; Middle English (h)oste (noun) < Middle French < Latin hospit- (stem of hospes) host, guest, stranger, perhaps < *hosti-pot(i)s or *hos-pot(i)s, equivalent to hos(ti)- combining form of hostis stranger (see host2) + -pot(i)s, akin to potis having the power to, posse to be able (see potent1) (hence, “one granting hospitality, one in charge of guests”); compare, with different initial elements, Greek despótēs master, despot, Lithuanian viẽšpats lord

A handful of domains will have restrictions on them, which means you can only purchase them if you meet or exceed certain criteria or have authorization (some examples are .gov, .edu and .mil). But most extensions are available to everyone. In fact, most country code Top Level Domains (ccTLDs) are available for anyone to purchase, even if you don't reside in the country code in question.

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.
