What Causes Website Downtime?

man-on-bike

We’ve all experienced websites which are unreliable, and appear to be offline when we need to access them. Perhaps you have had a similar experience with your own website, and know-how damaging downtime can be to your bottom line and to your brand image.

Whether a website is ‘down’ for an extended period of time, or for a matter of minutes, it can be extremely frustrating for anyone who is trying to access the site in that period. With improvements in cyber-security, computer hardware, and hosting coverage, website downtime is arguably less common than it was 5-10 years ago. However, this means that users are accustomed to having the information they require at their fingertips at all times. An experience with a website that is unable to meet these high standards is likely to result in a lasting negative impression that may be hard to shift.

In this article, we take a closer look at some of the causes of website downtime.

What is Website Downtime?

In its simplest form, website downtime occurs when a website is completely inaccessible to end-users. However, it is more often the case that only certain sections or elements of a website are inaccessible at any given time. For example, an e-commerce website where users are unable to complete a checkout would also be considered to be experiencing some form of downtime. In fact, it is often the case that the latter example can be even more frustrating to the end-user than a website that is completely inaccessible.

What Causes Website Downtime?

IT System Malfunctions

Each year the IT systems we use in the business world become faster, more adaptable, and more reliable. Despite this, the infallible IT system has yet to be created, and any single piece of IT hardware or software is subject to malfunction. When one of the components in an IT system fails, it can result in any number of issues for the IT infrastructure of an organisation, one of which is the status of the company website. Many such errors are relatively commonplace and will have no impact on website uptime at all. However, for companies who host their own website, any malfunction in the server hardware is likely to result in a period of downtime for the website.

Hosting Provider Errors

Downtime can be caused by a company’s internal servers malfunctioning, but most companies choose to host their website with a third-party provider, rather than internally. Generally speaking, this should minimise the risk of your website going offline, but only if you entrust your website into the hands of a reliable web hosting provider.

Cheaper web hosting providers are likely to offer an affordable hosting plan, but this will often come at the cost of reliability. Companies that offer cheaper web hosting may be using outdated server software, obsolete IT infrastructure, or non-virtualised servers.

Alternatively, your website could go offline because you have chosen a cheaper hosting plan, and you’ve experienced an unexpected spike in traffic. Even worse, perhaps you’ve forgotten to renew your web hosting plan altogether!

As you can see, web hosting is crucial to ensuring the constant uptime of your website. For more info, check out our article on How to Choose a Web Hosting Provider.

DDoS (Distributed Denial of Service)

While such instances are relatively rare, a DDoS attack (distributed denial-of-service) can take your website offline very quickly.

The purpose of a DDoS attack is to ‘deny service’ by overloading a server with abnormally high levels of traffic. This occurs by ‘jamming’ traffic to a server, resulting in a disruption of service for anyone else trying to access the website hosted on the server under attack.

A DDoS attack can pose a significant disruption to the normal functionality of a website and can result in an extended period of website slowdown and/or complete outage in the most severe cases.

Planned Downtime

Finally, one of the most common causes of websites being made inaccessible to the end-user is actually ‘planned downtime‘. Planned downtime occurs when an IT team undertakes an internal system update, such as upgrading hardware or software, integrating new equipment, or uninstalling redundant IT assets with the aim of improving the overall functionality of the company’s IT infrastructure. As planned downtime is accounted for in advance, potential website visitors should be forewarned if at all possible that they can expect to find the website offline in a certain time period. This will help to set expectations, and to minimise any potential customer or client dissatisfaction in the event that they attempt to access the website during the period of planned downtime.

A dedicated website uptime monitoring service can help you to proactively address any period of downtime by alerting you the moment your website goes offline.
