Your website is your business's front door. When it is down, nobody can buy, book or sign in. A few minutes of downtime costs sales and can cost you customers' trust, and a long or repeated outage can affect how Google crawls and indexes your pages. This post covers what downtime costs, what Google's documentation says about it, and what you can do to catch it sooner.

The Real Costs of Website Downtime

Downtime is a direct hit to your bottom line. Three costs show up first:

  1. Lost Revenue: When your website is down, customers can't buy, book, or engage. For an e-commerce store averaging $1,000 in hourly sales, 30 minutes of downtime means about $500 in sales that did not happen (some shoppers come back later, so treat it as an upper bound). A Gartner analyst wrote in 2014 that the figure Gartner typically cites for the cost of network downtime is $5,600 per minute, or well over $300,000 per hour, and stressed that it is only an average with a large degree of variance (Gartner blog, July 2014, archived copy). That figure is more than a decade old and is not specific to mid-sized companies. For current survey figures, see The Cost of Website Downtime: What the Research Shows.

  2. Damaged Reputation: Customers expect a site to work when they arrive. If it fails at the wrong moment, some will try someone else, and for a small business one lost client can matter a lot.

    Imagine a freelance graphic designer whose portfolio site crashes during a client pitch. That's not just a missed opportunity. It's a blow to their credibility. An alert as soon as a check fails lets you start fixing the problem sooner, though how soon depends on the check interval: every 5 minutes on our free plan, every 30 seconds on paid uptime plans.

  3. Search Visibility: Google's documentation says that 5xx and 429 server errors make its crawlers slow down, that URLs already in the index are kept but eventually dropped if the server errors persist, and that the crawl rate rises only gradually once your server responds normally again (Google Search Central, HTTP status codes and network errors). It does not say how long “persistently” is. A short outage is a smaller risk than a long or repeated one, but there is no safe duration to rely on.

How Site Qwality Helps

Downtime is costly, but you can shorten it. Site Qwality's HTTP checks run every 5 minutes on the free plan and as often as every 30 seconds on paid uptime plans. You decide what counts as a failure on each monitor, such as an unexpected status code, a response slower than a limit you set, or missing page content. The free plan checks from one location. Paid plans can check from several (see locations). Here's what that includes:

  • Alerts: Email, SMS (10 free credits a month), Slack, Microsoft Teams, Discord, Telegram, webhooks and more when a monitor goes down.
  • Failure Reasons: Every down alert names the monitor, the URL that was checked and the reason for the failure, such as a timeout or an unexpected status code.
  • Per-Phase Timing: Every HTTP check records DNS, TCP, TLS, time to first byte and download separately, so a slow site tells you which part is slow.
  • A Free Tier: Every product has one and none needs a credit card. Free uptime monitoring covers 100K checks a month at 5-minute intervals. See pricing.

Actionable Tips to Boost Your Uptime

You don't need to be a tech expert to keep your site reliable. Here are three simple steps you can take today:

  1. Choose a Reliable Host: Not all hosting providers are equal. Look for a published uptime commitment (an SLA), read what the host offers if it misses it, and check its public status history. Then verify the host's claims yourself with independent monitoring.
  2. Monitor Proactively: Use an uptime monitoring tool like Site Qwality to track uptime and response time. Knowing about issues before your customers do is half the battle.
  3. Test Regularly: Check critical pages (like your checkout or contact form) by hand every week to catch small issues early, or schedule a browser check that walks through them for you. The free plan includes 100 browser-check minutes a month.

What 99.9% Uptime Means

A 99.9% uptime target allows about 43 minutes of downtime in a 30-day month (0.1% of 43,200 minutes). A 99.99% target allows about 4.3 minutes. Monitoring can't prevent an outage, but it measures your real uptime and shortens the time before you know about one. The uptime calculator converts any target into minutes.
