What is up time and what is the threat of disruptions in the work of the site


Imagine that you are looking for a specific product or service. You find a company in a search engine and you’re ready to take advantage of the offer, but you go to the site and find that it doesn’t work. The next step is to close the page and find an accessible resource. This is exactly what the users of your site do.

In order not to lose customers and not to suffer losses, it is important to regularly site monitoring – check their operability and correct functioning. There are two important concepts: uptime и downtime – percentage of time when the server itself and its components were available and unavailable, respectively. Let’s look at what this means, why it’s so important, and how to measure uptime.

What a properly configured site monitoring will do

Tracking the performance of the site will allow:

  • Detect hosting problems and hidden bugs of the resource itself.
  • Identify virus infections that affect the security of of your site and visitors’ devices. Remember that the prolonged presence of harmful code is fraught with lower positions in search results.
  • Rationally allocate budget for promotion. The collapse of the servers can reduce all SEO efforts to almost nothing. If the site is inaccessible, but at this point the search robot comes to it, the pages are not included in the index, which also leads to a deterioration in the rankings. In this case, you do not need to allocate more money to the promotion, and to ensure a high up-time.
  • Understand why sales are not growing. The first thing most business owners blame an ineffective advertising campaign, but it’s not always about marketers. If a customer sees an attractive ad, decides to contact you, but can not go to the site, most likely, he will go to a competitor. Getting him to reach out to resource after some time can only untwisted brand and a high level of loyalty to your company.
  • Evaluate the quality of service of the hosting provider. With low uptime, it makes sense to think about changing hosts.

In addition to your own site, you can track the performance of competitors’ resources. This will allow you to understand whether you are in an advantageous position in comparison with them.

What is website uptime

What is the optimal interval for checking availability?

As a preventive measure site accessibility monitoring can be performed once every 10 minutes. This is enough to identify errors and correct them promptly. After all, many visitors, especially regular visitors, will return to the page after some time time.

If “floating” errors are detected (related to the influence of several factors), then the minimum frequency of checking should be once a minute. This will require distributed monitoring – tracking from multiple access points. This refers to checking the availability of the site from different regions and devices. When the problem is solved, you can go back to the normal mode at 10-minute intervals.

Are short-term malfunctions a problem?

In itself, the inaccessibility of the site for a short time is not very scary. There are several reasons for such failures: server overloaded, problems with peer-to-peer networks or routing. However, to be sure that this failure will not last much longer, you can’t. To avoid critical consequences, we recommend that you set the frequency of the check. On many services you can set the frequency of monitoring after a failure is detected – once a minute until it is eliminated. If you are intimidated by the multitude of notifications in such situations, set them to be sent only after several errors occur in a row.

Site failures always carry risks, but their extent depends on how quickly the problem is fixed.
