# High-Traffic Website Hosting UK Source: https://dijituldns.co.uk/high-traffic-hosting/ Updated: 2026-10-08 > dijitul hosts high-traffic websites and online shops in the UK on dedicated, tuned servers, quoted after we review your traffic and application. We size CPU and memory to your peaks, tune PHP-FPM and MariaDB, add Redis object caching and page caching, and put Cloudflare in front to absorb spikes from sales, press coverage or TV mentions. ## Key facts - Quoted after reviewing traffic, platform and peak patterns - Dedicated resources on a VPS, cloud or dedicated server - PHP-FPM and MariaDB tuned to your workload - Redis object caching and full-page caching where suitable - Cloudflare CDN caching and protection in front of the server - Load testing and monitoring before big events ## When a site outgrows standard hosting Most small business sites sit comfortably on [dijitul Complete Hosting](https://dijituldns.co.uk/complete-hosting/). A site needs more when it has steady high traffic, sudden peaks, or heavy pages that each do a lot of work. Signs include: pages slowing at busy times, checkout timeouts during sales, database errors under load, or the host telling you you're over your limits. ## What we look at first - **Traffic shape:** average and peak visitors, and when peaks happen. - **How dynamic the site is:** a blog can be cached heavily; a logged-in forum or a busy WooCommerce checkout can't. - **Slow queries:** a single bad database query can cost more than any hardware upgrade fixes. - **Plugins and modules** that do expensive work on every page load. - **Media weight:** large images and video that should be optimised or offloaded. - **Background jobs:** imports, feeds and emails that compete with visitors. ## How we build for traffic - **Right-size the server.** A [managed VPS](https://dijituldns.co.uk/managed-vps/) or [dedicated server](https://dijituldns.co.uk/dedicated-servers/) with enough CPU cores and RAM for your peak. - **Tune PHP-FPM.** Worker counts set to match memory, so the server doesn't swap under load. - **Tune the database.** MariaDB or MySQL buffer pool sized to your data, slow query log on, indexes added where needed. - **Cache in layers.** Cloudflare at the edge, full-page cache for anonymous visitors, Redis object cache for the application, OPcache for PHP. - **Move heavy work off the request.** Cron or queue workers for imports and emails. - **Watch it.** Monitoring for CPU, memory, disk and response times, with alerts. ## Planned peaks If you know a spike is coming, such as a Black Friday sale, a product launch, or a TV or radio feature, tell us early. We can test the site under load, warm caches, pause non-essential jobs and add capacity for the event. Unplanned spikes are handled better when caching is already in place, which is why we set it up from day one. ## Questions we'll ask - Which platform and version: WordPress, WooCommerce, Magento, Laravel, a forum? - How many visitors a day, and what's the biggest peak you've seen? - How many orders, posts or logins per hour at the busiest time? - How large are the database and media library? - What has gone wrong at busy times before?

A server with dedicated resources, usually a VPS or dedicated server, plus layered caching: a CDN such as Cloudflare, full-page caching, Redis object caching and a tuned database. dijitul specifies and manages this for UK sites on a quoted basis. ### Why does my website slow down when traffic increases? Usually because every visit makes PHP and the database do work, and the server runs out of PHP workers, CPU or memory. Caching, query fixes and right-sized PHP-FPM settings help more than raw hardware. dijitul reviews this before quoting. ### Will Cloudflare stop my site crashing under heavy traffic? It helps a lot for cached pages and static files, and it blocks junk traffic. It can't cache logged-in pages, baskets or checkouts, so the server still needs enough capacity for those. dijitul combines both. ### How many visitors can shared hosting handle? There's no fixed number. A cached brochure site handles far more than an uncached shop. The real limits are CPU, memory and PHP workers. If your site slows at busy times, it's time to look at dedicated resources. ### How do I prepare my online shop for Black Friday? Load-test early, make sure full-page and object caching are working, fix slow queries, pause heavy background jobs during the sale, and confirm your host can add capacity. dijitul does this for customers on quoted high-traffic hosting. ### Is Redis worth it for WordPress or WooCommerce? On busy sites, often yes. Redis stores database query results in memory so repeated requests are faster, which particularly helps logged-in users and WooCommerce. On small quiet sites the benefit is small. ## Pricing and ordering This is quoted to fit. Request a quote at https://dijituldns.co.uk/quote/ or call 01623 650333.
