Every minute your website is down costs you money — in lost sales, eroded trust, and wasted ad spend sending visitors to a broken page. Yet most UK businesses only discover an outage when a customer complains. Uptime monitoring flips that equation: you get notified first, before anyone else notices.
What uptime monitoring actually does
An uptime monitor periodically sends a request to your website or service — typically an HTTP request — and checks whether it gets the expected response. If the response fails, times out, or returns an error status code, the monitor raises an alert. Most modern tools go further, checking TCP ports, DNS resolution, SSL certificate validity, and even SEO signals like your PageSpeed score.
The cost of downtime in 2025
Research from Gartner places the average cost of IT downtime at around £4,000 per minute for enterprise businesses. For SMEs the figure is lower but the proportional impact is often greater. A 30-minute outage during a campaign launch, a payment gateway failure on payday, or a DNS misconfiguration after a domain renewal can each wipe out days of marketing effort.
What checks should you run?
HTTP checks confirm your web server is responding with a 200 OK. TCP checks verify specific ports are open — critical for mail servers, databases, and custom APIs. DNS checks confirm your domain resolves correctly. SSL checks track your certificate expiry so you are never caught with a browser security warning. SEO checks measure your Google PageSpeed score and verify your meta tags are intact after every deployment.
