Quick Status Check
Results in Under 2 Seconds
We send an HTTP request to the site and measure the response time, so you know immediately if there's an outage.
Checks from AWS US-East
Our backend runs on AWS Lambda in us-east-1. If the site responds to us but not to you, the issue is on your end.
Ad-Free
Unlike most outage checkers, there are no ads, pop-ups, or cookie walls between you and the answer.
No Account Needed
Just type a URL and hit check. There's nothing to sign up for and nothing to install.
Frequently Asked Questions
When you enter a URL, our backend (running on AWS Lambda) sends an HTTP request to that site and measures whether it responds and how long it takes. You get the actual HTTP status code and response time, not a guess based on user reports.
Downdetector aggregates user-submitted reports, which means results lag behind the actual outage and can spike from social media rumors. This tool makes a real HTTP connection to the site and tells you what happened. If we get a 200 OK, the site is up. If we get a timeout, it's not.
Our check runs from AWS us-east-1. If we can reach the site but you can't, the problem is between you and the server. Common causes: your ISP is having a routing issue, your DNS resolver has a stale cache, or the site is geo-blocking your region. Try flushing your DNS or switching to 1.1.1.1 or 8.8.8.8.
This tool is for on-demand manual checks. If you need continuous monitoring with alerts when your own site goes down, Status Tiger runs scheduled checks every 30 seconds and can notify you via email, Slack, or Discord.
The most common causes are server overload during traffic spikes, bad deployments that crash the app, expired SSL certificates (which browsers treat as a hard failure), DNS misconfigurations after a migration, and DDoS attacks. Scheduled maintenance is another common cause, though well-run sites announce that in advance on their status page.
