Hit the leaderboard with your own monitors

Sites at the top of this leaderboard run more than just an uptime check. Match the standard with continuous monitoring across the categories that matter:

HTTP uptime monitoring
The foundational check that drives the leaderboard percentage.
SSL certificate monitoring
Expired certificates are one of the top causes of uptime drops.
DNS record monitoring
DNS misconfiguration takes more sites offline than infrastructure failure.
Response time monitoring
Slow responses count against availability on most strict SLAs.
Domain expiry monitoring
Expired domains are a common, embarrassing reason sites drop off the leaderboard.

Or run a one-off website health score to see how your site stacks up before you start monitoring.

How is uptime calculated for the leaderboard?
Each site on the leaderboard is checked from our edge network, and the percentage shown is the share of successful checks over the rolling last 30 days. A successful check means a 2xx HTTP response within the response-time threshold, with a valid SSL chain. Failures, timeouts, and 5xx errors all count as downtime.
Every 5 minutes. The 30-day uptime percentage is recomputed continuously as new check results come in, so the rankings reflect the most recent monitoring data — not a snapshot from days ago.
The leaderboard is curated from popular public sites we already monitor on the public tracker. To track your own uptime privately, sign up for a free Uptrue account — you get the same monitoring engine, alerts, and 30-day uptime stats on your own dashboard.
Roughly 4.3 minutes of downtime per month, or 52 minutes per year. Sites at this tier typically run multi-region failover, CDN-fronted origins, and continuous SSL certificate monitoring. Most outages at this level come from DNS or certificate misconfiguration, not infrastructure failure.
The leaderboard is honest. Even well-known services have intermittent failures — slow SSL handshakes, regional outages, expired certificates, response time degradation. The leaderboard captures all of this, not just complete outages. Click any site to see its incident timeline.
Sites that rank in the top 10 can embed a "Top 10 on Uptrue Leaderboard" badge. The badge updates dynamically — if a site drops out of the top 10, the badge automatically reflects the new ranking.
