Most website outages have nothing to do with sophisticated attacks or bugs in the code. More often a site stops working because of small things nobody was keeping an eye on. The usual list looks like this:
All of this is caught by simple routine checks, and that is exactly what website support is built on: tracking renewal dates, monitoring uptime and sending test form submissions, rather than reacting after customers have already started calling.
Every CMS and module update closes holes that have been found. Once a fix is released, the details of the vulnerability become public, and sites on the old version turn into easy targets: they are found and hacked automatically, with no interest in your particular business.
The damage from an infection rarely stays on one page. Attackers plant spam links and hidden pages, redirect visitors to other sites and use your hosting to send spam. Yandex and Google flag the site as dangerous, browsers show a warning, and the host may suspend the account. Recovery means cleaning the code, finding every backdoor, changing passwords and requesting a review from search engines, and it costs noticeably more than regular updates, not counting the leads lost during downtime.
Updating blindly is risky too: a new module version may conflict with older code. The right order is a fresh backup, an update on a staging copy, a check of key user flows, and only then a rollout to the live site.
Our website maintenance plans differ mainly in the monthly pool of hours and how deeply we're involved in the project. The entry level, from $150 a month, covers the technical side: monitoring, backups, updates and security. The middle plan adds regular content edits and small improvements. The top plan suits sites that are actively growing, with a steady flow of tasks.
To choose a plan, consider three things: how often you make changes, what an hour of downtime costs your business, and whether new sections or integrations are on the roadmap. A simple business card site with rare edits will do fine on the entry plan, while an online store with daily updates needs headroom in hours.
Large tasks that don't fit into a monthly package, such as new features, a redesign or a move to another CMS, are usually estimated separately. Paid module licences and hosting aren't part of the support fee either, and it's worth agreeing on this upfront so the contract holds no surprises.
