DNS
DNS DNS - domain name system, a system for locating a web site.

DNS - domain name system. This system helps to find a real server by virtual site name. The system is realized by the hierarchy of DNS servers, each of them holds information about specific domains and may delegate such role to lower stage servers. Let's take, for example, site www.host-tracker.com. The upper domain is .com, so the request is made to the server, which is responsible for all .com sites. It knows where each site is located, or at least, where is another server, which knows for sure. If you get "Server not found" message, that means no record exists on the DNS server for the site name you've requested.

Each time you enter an address into the browser - a DNS request is made, in order to find where the site is located. To make this process faster, DNS data can be saved into a cache. If you own a site and decide to change its name for some reason, or if you have just created the new one - you should keep in mind that DNS cache needs some time to be updated globally. Usually, it happens within couple of hours, but it can take up to 48 hours. That's why sometimes a newly-hosted site can not be visible for some time.

Active Monitoring Active Monitoring is the way to check the site performance by simulation of visiting by real users.

Active Monitoring is the way to check the site performance by simulation of visiting by real users. It is done by external service, usually with distribyted networks. The checking servers create the requests like the real clients, who are trying to download a web page. Doing it on regular schedule, allows to check if the page is available from the web. If not - there is a possibility to catch and report the error. The difference between the bot and a real person is visible only for bulky pages with lots of content - in order to save the traffic, monitoring systems usually download only a part of such pages, which is enough to make sure the site is Ok.

Active monitoring is an independent eye on your site. The checking is not connected to your company and web hosting, and so provides the clear third-party view of the situation. HostTracker service uses active monitoring to supervise web sites.
