How often should a website be checked for uptime?

Choose a check interval based on the page's business impact, recovery process and documented plan limits. Critical public endpoints usually need more frequent checks than low-risk content.

• A shorter interval reduces the maximum time before the next observation, but it also produces more checks and more noise to assess.
• Use lightweight requests where they accurately represent the customer journey; a HEAD request does not always behave like a browser GET request.
• Cache behaviour, DNS, rate limits and bot protection can affect what a monitor sees.
• Use confirmation rules or a second independent check where the tool supports them, then test the alert path deliberately.
