Artificial intelligence (AI) is changing multiple industries – but what about the one that keeps the World Wide Web online?
While much of the world’s focus has been on how AI is changing the world of work and improving our personal lives, it has slipped into the data centre rack so quietly that many website owners haven’t noticed their infrastructure is already co-managed by algorithms.
But across the huge, multi-billion-dollar web hosting market, machine learning systems now decide when extra servers spin up, spot cyberattacks in milliseconds, and even answer many helpdesk tickets. The result is faster pages, fewer outages and – at least for early adopters – leaner power bills.
The most obvious change is invisible to users: predictive auto-scaling. Instead of reacting to traffic spikes, cloud platforms model them hours in advance.
Microsoft’s Azure predictive autoscale analyses past CPU patterns on each virtual-machine cluster and adds capacity before the surge hits, heading off slowdowns without wasting hardware during lulls.
Microsoft is far from alone: Amazon Web Services takes a similar approach, feeding weeks of load data into machine-learning models that forecast demand for EC2 instances and expand Auto Scaling groups automatically.
Content-delivery specialists like Cloudflare supplement that with AI-driven traffic management, routing requests to the quickest edge server and smoothing global peaks. Together, these tools promise a kind of anticipatory uptime: the site stays fast because the algorithms are ready.
Stopping traffic at the door
Security teams are leaning just as heavily on machine learning. ScalaHosting’s SShield watches every request to client sites and, according to the company, blocks 99.998% of malicious traffic by training on the latest attack patterns. Larger clouds embed comparable defences in their web-application firewalls, sifting billions of logs for anomalies that signal a zero-day exploit or botnet swarm.
The advantage is two-fold: faster detection and far fewer false alarms, which is a chronic headache for human analysts.
But AI is not simply helping in identifying risks. It’s also answering support queries once fielded by call-centre staff.
At Lithuanian host Hostinger, their homegrown AI chatbot Kodee resolves about 5,500 tickets every day in 50 languages, with an average response time of 20 seconds – solving roughly half of all issues before a human agent is pinged.
Executives say the bot’s workload is equivalent to “more than 100 employees”, freeing specialists to tackle knottier problems and cutting payroll costs.
However, efficiency gains are not only measured in headcount. As early as 2016, Google used its DeepMind unit to tune cooling pumps and fans in real time, trimming energy for air-conditioning by 40% and boosting overall power-usage efficiency by 15%.
Given AI advancements over time, those figures are only likely to improve. Hosting firms now pitch such savings as proof that AI is a sustainability tool as much as a performance one: by predicting load precisely, they can consolidate workloads at night and let idle servers sleep, shrinking electricity bills and carbon footprints.
AI under the hood, everywhere
The momentum is industry-wide. An April 2025 PagerDuty survey found that 71% of companies with mature generative AI programmes had already deployed “agentic AI” in IT operations, and most expected triple-digit returns on investment.
Vendors frame the trend as a march toward self-healing infrastructure: systems that diagnose faults, patch themselves and only inform engineers after the fix is in.
Yet, it’s worth remembering AI can be a double-edged sword, and the benefits can be cancelled out – or outweighed – by the drawbacks.
Sceptics warn of new dependencies. If a scaling model drifts or an AI firewall overblocks an IP address, thousands of sites could go dark at once. There are workforce fears, too: while senior engineers still vet the algorithms, tier-one support and routine admin roles are shrinking.
But for businesses that demand uninterrupted uptime, the appeal is clear. In an industry where milliseconds and megawatts both hit the bottom line, that quiet concierge work by AI could soon be the new definition of good hosting.
