Load shedding ruins a lot of things. Dinner plans. Your UPS battery. And if you're not paying attention, your website.
Most business owners don't connect the two. Between local servers going dark during outages, painfully slow page loads on mobile data, and hosting providers quietly cutting corners, your website's performance might be bleeding you dry without a single error message to show for it.
How Load Shedding Directly Hits Your Website
If your site is hosted on a server physically sitting in South Africa, especially with a smaller budget provider, load shedding is a genuine threat. Power goes out at the data centre, the backup generators fail or run dry on diesel, and your site goes down. No warning. No graceful fallback.
During Stage 6 in late 2023, several SA hosting providers had multi-hour outages. Businesses on those hosts lost orders, lost enquiries, lost credibility. A customer who hits an error page doesn't bookmark your site and try again later. They go straight to your competitor.
Even when generators kick in properly, constant power cycling wears hardware down over time. You get intermittent slowdowns and random downtime. Death by a thousand cuts.
Why Global CDNs Beat Local Hosting
A Content Delivery Network distributes your website across servers worldwide. When a customer in Joburg visits your site, they get served from the nearest edge node (which might be in Johannesburg), but the origin server sits safely in a world-class data centre that doesn't care what stage Eskom is on.
Platforms like Vercel and Cloudflare host websites on global edge networks with 99.99% uptime guarantees. Your site loads fast whether the visitor is in Durban, London, or Lagos. When load shedding hammers SA, your site stays up because it's not tethered to local infrastructure.
We host all our client websites on these platforms. It's a core reason we can offer the reliability businesses need. More details on our maintenance and hosting packages.
Mobile Data Is the Bottleneck Nobody Tests For
Over 70% of South African internet users browse primarily on their phones. Most are on mobile data, not fibre or Wi-Fi. And data is expensive here relative to income. Network speeds outside major metros can be brutal.
Your homepage that loads 5MB of uncompressed images? Fine on your office fibre. Takes 15 to 20 seconds on a 3G connection in Limpopo. That customer is gone before the page finishes rendering.
Speed Optimisations That Actually Matter for SA
- Use WebP format and compress every image. A hero image should be under 150KB, not 2MB
- Lazy load images and videos so they only download when they scroll into view, saving precious data for mobile users
- Strip out unnecessary JavaScript. Every unused plugin and widget adds load time
- System fonts can save 100 to 500KB in downloads compared to custom fonts. If you must use custom fonts, load only the weights you need
- Set caching headers so returning visitors don't re-download assets they already have
What a Slow Website Actually Costs You
Google's research puts it at 53%. That's the share of mobile users who abandon sites taking longer than 3 seconds to load. In South Africa, where patience with slow connections is thinner, that number is probably higher.
Bounce rates are only half the problem. Google uses page speed as a ranking factor. A slow site means lower rankings and fewer people finding you in the first place. You get less traffic arriving and more of it leaving before seeing your content.
If your current website drags, it could be one of the signs your website is losing you customers.
How to Test Your Speed on SA Networks
Don't just load your site on office Wi-Fi and assume it's fine. That tells you nothing about what your customers experience.
- Google PageSpeed Insights is free. It scores your mobile and desktop speed and tells you exactly what to fix
- In Chrome DevTools, go to Network and select "Slow 3G." Now you're seeing what your customers see on mobile data
- WebPageTest.org lets you test from different locations and connection speeds
- Open your site on an entry-level Android phone using mobile data. If it frustrates you, it's frustrating your customers
What You Can Do Right Now
If your site is with a budget SA host and you've been experiencing downtime during load shedding, move. Modern hosting on global edge networks costs roughly the same as traditional local hosting but delivers dramatically better performance and reliability.
If your site just loads slowly, an optimisation pass (compressing images, enabling caching, stripping unnecessary scripts) can often halve your load times without a full redesign.

Your customers won't wait. Not when your competitor's site loads in under two seconds.
