Website monitoring
Website monitoring Website monitoring is an automated process of checking availability of a site.

Website monitoring is an automated process of checking availability of a site. The main goal of it is evaluation of possibility to access the site by clients. It is clear, that a site is efficient when an interested person can load the page and make a purchase or look for some information. If this action fails for some reason - the site does not execute its mission, and a client will find what he needs somewhere else.

There are many solutions of this problems, and all of them could be divided into passive and active ways. The result of monitoring is the value of uptime, measured with some accuracy. Having it, one can conclude how long is the site broken during some period of time (usually, for a year). Low uptime usually means that the server where the site is hosted, or internet connection to it, is unreliable and is required to be changed.

"Thank you so much for your service. We were suspecting problems with our hosting company but they denied any problems saying the issues must be at our end. We know we do have issues at our end but still suspected that wasn't the entire story. Your service was able to prove that they are indeed going down regularly - on average twice a week during the trial period. Thanks again for providing the information we needed to make a proper decision on this issue."

Blacklisted again? Why does this keep happening to me?!

We’re happy to announce that this tool has just got even more awesome! Now you can use our DNSBL check tool as a one-time job or on a regular basis. It means you can keep your IP address in a continuous check against dozens of the most popular blacklists. 

Previously, we have introduced one of the “Check site instantly ” board functions -  DNSBL - which helps you find out whether your server is blacklisted before it gets out of control.

We’re happy to announce that this tool has just got even more awesome! Now you can use our DNSBL check tool as a one-time job or on a regular basis. It means you can keep your IP address in a continuous check against dozens of popular blacklists. 

This can significantly ease your website’s life online, moreover, bring balance into it.

New options

With the new extension of the DNSBL check tool, it's become easier to test your website accessibility, as well as, server message deliverability.

For example, suppose your IP address is currently on the DNSBL monitoring. The moment your website is found blacklisted, our system will report back to you all the detailed information on the check results - the name of the blacklist (which one of the DNS-based anti-spam lists recognize you as a source of spam activity) and the reason for listing (this information is public and provided directly by DNSBL databases).

All this will allow you to quickly clean up “the mess”, speed up the process of domain removal (delisting), protect your business reputation and, by extension, prevent recurrence of such a problem in the future.

HostTracker, as a website monitoring service, always keeps moving forward - our list of DNSBL servers is constantly updated.

The whole setup process will take you only a few minutes to complete:

Some Secrets of Activating Blacklist Monitoring

The good news is that you’re opted to activate the DNSBL check for already existing monitoring tasks. All you need to do is to put a tick mark in the box next to “DNSBL check” field when editing or adding a check task.

Once enabled, HostTracker starts gathering information about your website availability and checking whether your IP is currently listed. A Contact Group for notifications will be automatically added to the current test task. If our system finds your server blacklisted, you’ll immediately receive a message with the relevant information.

We hope that with such a tool you’ll enjoy the convenience, simplicity and quality of our all-in-one monitoring service. If you have any questions or suggestions, feel free to contact us - we’re always looking for ways to improve!

It is rather strange, but instead of going down web services usually grow so overloaded with the user requests that after slowing down they become unresponsive. But nowadays it is extremely important to provide secure and high-quality web hosting services, available anytime, as e-businesses is acquiring popularity. The owners of the websites demand perfect service, 100% uptime and quality assurance. Numerous techniques may be used to make access to the website smooth, thus increasing uptime. Site uptime informer

Here we offer you twelve methods recommended to achieve performance gain and uptime increase. Software optimization is required for that, as well as hardware optimization. A lot of software features may be upgraded with the use of general and improved coding standards, operated by the website manager. At the same time the company providing the webhosting services needs to improve the hardware constantly.
You can measure the accessibility of the website using monitoring services HostTracker.

Software Optimization
The following are the first six ways to improve uptime:

  • Split the databases
  • Separate the read an write databases
  • Use popular content caching more often and improve its quality
  • Optimize static content
  • Ensure compressed delivery of content
  • Optimize the content management system


To begin with, splitting  the databases – horizontally or vertically, or combining these two directions - is essential, making the connection more reliable. It is also good to differentiate the read and write databases, this giving an opportunity for master/slave setup. These actions are useful to extend the database infrastructure for future use.

Second, when you set the system to use better popular content cache, and to use it more often, your site will scale up more easily with many users operating it. Internet caching has no difference from computer caching: it supposes storing popular content at a separate container, allowing much quicker access to the information for the users.

To optimize static content is one more way to make the access to internet pages and files quicker. One of the means for it is to compress the images to the maximum extent possible (but, of course, preserving their high quality). Moreover, it is necessary to check if the web server may be used to deliver compressed content; this characteristic is not connected with the images, as they are already compressed files. Take care to have all the appropriate settings from the beginning.
.
One more appropriate thing to do is to improve the system of content management reducing the database calls number for each page request. It is like any type of connection: at the decrease of the information sending times the connection is maintained. In this circumstances, the number of calls to the database should be as low as possible – it will ensure that the users are able to access the content with the greatest speed.

Software and Hardware Optimization
The next six methods for augmenting uptime are:
Six more ways to augment the uptime are the following:

  • Use content delivery networks
  • Use emerging standards, such as HTML5
  • Improve the programming techniques
  • Add the content “expires” headers
  • Lessen the number of HTTP requests
  • Use Ethernet connections, allowing for more speed


Contend delivery networks allow for operation over larger amounts of media, at the same time improving the performance of the site. They are developed to direct the traffic to private networks. Such services allow operation over large media files, rooting the traffic along the Internet age, not straightly, averting extreme overloading. As the content delivery networks operate with large files, this unloads the servers, providing quick and qualitative connection.

Emerging standards, such as HTML5, include systems, improving the websites. It is achieved through advanced programming techniques, aimed at website and internet communications. Such standards do not 100 % assure that the website that uses them will not go down, but the in-built mechanisms of the code will act as the auxiliary mechanisms if it happens. Moreover, you should use improved programming methods while working with large loads and traffic spike.

“Expiers” content headers make all the automatically downloaded files cacheable for the visitors. So adding these headers to the content you will prevent the constant downloading of the browser. It blocks page review pointless HTTP requests. As well as the reduction of the database calls number, the reduction of the HTTP requests number will make the connection speed stable and not overloaded.
The last method is to develop Ethernet connection speeds. This will allow to cope with larger files and unexpected traffic spikes. A lot of hosting providers consider it as an excellent investment.

Speeds improvement and downtime reduction make the customers happier. Many of these methods to improve the web server or web site uptime may be achieved in a few minor steps. Such tactics, including Database rearrangement software optimization, caching improvements, content compressing, use of content delivery networks and content management systems, programming practices improvements and hardware upgrading will improve the web host as well as web site uptime, thus also improving your business.
