In this article, we will explore what server uptime and downtime are , how to measure them, what are the most common causes, how to prevent them, and how to choose the best hosting to ensure maximum availability of your website. We will also give you some practical tips to better manage downtime situations and minimize damage.
Server uptime is the period during which the server remains active , thus ensuring the accessibility of the website to visitors. This time interval is expressed as a percentage and reflects the proportion of server availability in a specific period of time.
For example, a 99.9% uptime for a month means that the server was operational for 99.9% of the total hours in the month, with only 0.1% downtime.
Uptime is a crucial parameter for evaluating the quality and reliability of a hosting service. A high esinc email list uptime ensures that the website is constantly online, favoring the acquisition of traffic, the generation of conversions, the dissemination of information and the satisfaction of user needs.
Conversely , reduced uptime leads to website downtime, resulting in lost opportunities, damaged reputation, erosion of trust, and a negative impact on revenue.
Server uptime is determined using dedicated monitoring tools. These monitors perform periodic checks on the status of the server and the website, sending notifications in case of anomalies or service interruptions.
Monitors vary in their specific capabilities: some check server availability at the network level, others at the operating system, application, or content level. Popular tools in the industry include Pingdom , Uptime Robot , StatusCake , and Site24x7 .
To calculate uptime, the formula is applied:
Uptime (%)=(Total TimeTotal Time−Downtime)×100
For example, if we consider a total period of 30 days and a downtime of 43 minutes, the server uptime is calculated as follows.
