Website Uptime Checker
Check if any website is up or down right now. Test HTTPS, response time, DNS, redirects, robots.txt, and sitemap availability.
Why Monitor Website Uptime?
SEO Impact
Google crawlers visit your site regularly. If your site is down during a crawl, it can hurt indexing and rankings. Frequent downtime signals unreliability to search engines.
Revenue Loss
Every minute of downtime costs money. E-commerce sites lose sales, SaaS products lose subscribers. Even 99.9% uptime means 8.7 hours of downtime per year.
User Trust
Users who encounter a down website are unlikely to return. 88% of users won't return after a bad experience. First impressions matter.
SLA Compliance
If you offer services with SLAs, undetected downtime means violated agreements and potential penalties. Proactive monitoring helps you catch issues first.
What This Tool Checks
Frequently Asked Questions
How accurate is this uptime check?
This tool performs a real-time check from our servers. It tests HTTPS connectivity, response time, and several health indicators. For continuous monitoring, consider our Pro plan which checks every 5 minutes and sends alerts.
What is a good response time?
Under 500ms is excellent, 500ms-2s is acceptable, and over 2s indicates potential performance issues. Response time depends on server location, hosting quality, and page complexity.
Does downtime affect SEO?
Yes. Google's crawlers can't index pages they can't reach. Short outages (minutes) are fine — Google retries. But extended downtime (hours+) or frequent outages can cause pages to be deindexed and rankings to drop.
What's the difference between HTTP and HTTPS?
HTTPS uses SSL/TLS encryption to secure data in transit. Google requires HTTPS for ranking benefits. If your site doesn't redirect HTTP to HTTPS, you're losing SEO value and potentially exposing user data.
