Server Status Checker - Check 20 URLs Free

A server status checker tells you whether a website's server answers requests, which HTTP status code it returns and how long it takes to reply. Paste up to 20 URLs, one per line, and this free tool returns a response summary plus a per-URL table, so site owners and SEOs can spot downtime in seconds.

What Is Server Status?

Server status is the HTTP response a web server gives when something asks for a URL. That response includes a three-digit status code, and the code tells browsers and search engine crawlers whether the request worked, moved or failed.

The first digit sets the category. A 200 means the page was delivered, a 3xx means the URL redirects somewhere else, a 4xx means the request has a problem on the client side, and a 5xx means the server failed. When no response arrives at all, there is no status code, and the site is effectively down for that visitor.

People often search "what is server status 429." It means the server received too many requests in a short time and is asking the client to slow down. It is a rate-limit signal, not a sign that the site is gone.

How to Check Server Status of a Website

You can check the server status of a website by pasting its address into the box and submitting the form. The steps below match the page you see on this tool.

1. Click the large text box. The placeholder shows the format: example.com, google.com and github.com, each on its own line.
2. Type or paste one URL per line, up to 20 URLs. Blank lines are ignored.
3. Add the full address when you care about a specific page, such as example.com/pricing. If you leave out http:// or https://, the tool tests the address with https://.
4. Press the submit button under the box to run the check.
5. Read the summary cards first: Total, Responded, Unverified / invalid and Avg Response.
6. Scan the results table for each URL, its HTTP code, its response time and its status.
7. Use the link at the bottom of the results to return to the form and run a new batch.

Worked Example: Reading a Three-URL Check

Say you run a small shop and you paste these three lines after a site update: example.com, example.com/old-page and shop.example.net.

The tool might report this:

• example.com: HTTP 200, 0.420 Sec, Responded.
• example.com/old-page: HTTP 404, 0.310 Sec, Responded.
• shop.example.net: HTTP Unverified, Unavailable, Unverified.

The summary would show Total 3, Responded 2, Unverified / invalid 1, and Avg Response 0.365s, which is (0.420 + 0.310) divided by 2. Notice that the average only counts URLs that answered.

Here is what that means. The homepage is healthy. The old page reached a working server, but the page itself is missing, so you need to restore it or add a redirect. The third URL gave no response at all: check the spelling, the DNS record and whether the host is running.

How to Read and Act on the Results

Each result row combines a status code, a response time and a status label, and you need all three to judge a URL.

The summary cards

Total is the number of URLs you submitted. Responded counts every URL that returned any HTTP status code, including errors such as 404 or 503. Unverified / invalid counts everything else. A "Responded" label therefore means the server answered, not that the page is correct, so always look at the code too.

The HTTP code column

Codes are color-coded: green for 2xx, blue for 3xx, red for 4xx and 5xx, and gray when no code was observed. The tool follows redirects, so the code shown is the one from the final destination. A URL that redirects to a working page appears as 200.

The response time column

Response time is the total time in seconds for the request, including connection and page download. A widely used guideline for time to first byte is under 800 ms, and total time runs a little higher than that. If a simple page regularly takes more than 1 to 2 seconds, look at hosting resources, caching and heavy plugins. You can also confirm that GZIP compression is enabled to cut transfer time.

Fixes for common outcomes

• 200 and fast: healthy, no action needed.
• 404: restore the page, fix the internal link or add a 301 redirect to the closest replacement.
• 403: a firewall, hotlink rule or permission setting is blocking access.
• 429: the server is rate limiting. Wait a few minutes and test again.
• 500 or 503: check server logs, recent deployments and resource limits. A 503 is also the correct code for planned maintenance.
• Unavailable: no response came back. Check DNS, the hosting account, SSL setup and whether the server is up.
• Invalid URL: fix typos, spaces or unsupported characters.
• Public hosts only: the tool cannot test private or internal addresses, only publicly reachable websites.
• Time limit reached: the batch took too long. Run the remaining URLs in a smaller group.

Why Server Status Matters for SEO

Server errors affect crawling and rankings because Googlebot cannot index a page it cannot fetch. Google's Search Central documentation explains that repeated 5xx and 429 responses cause Googlebot to slow its crawl rate, and URLs that keep failing can eventually drop out of the index.

That makes a quick status check a useful habit after a migration, a plugin update or a hosting change. If you need to confirm that important pages are still listed after a problem, run them through the Google Index Checker.

Who Should Use This Tool and When

This tool suits anyone who needs a fast yes-or-no answer on whether sites respond, plus the code behind the answer.

• Site owners: confirm your site is reachable when a customer says it is down. Test both the www and non-www versions, and both http and https.
• SEO specialists: spot-check key landing pages after a release or redesign.
• Agencies and freelancers: test a client's domains, subdomains and staging URLs in one pass.
• Developers and sysadmins: verify a deployment, a DNS change or a new SSL certificate from an outside request.
• Content teams: check that old campaign URLs still resolve or redirect.

If you need to test more than 20 addresses, the Bulk HTTP Status Code Checker handles up to 100 URLs at a time.

Best Practices and Troubleshooting Tips

Better input gives clearer results, and a few habits prevent most confusing readings.

• Test exact URLs. A homepage can return 200 while a deep page returns 500. Include the pages that earn traffic or revenue.
• Keep one URL per line. Commas or spaces between addresses make a line invalid.
• Stay at 20 or fewer. Pasting more shows the message "Enter up to 20 URLs per check."
• Run a second check before escalating. One slow or failed response can be a brief spike. If a URL fails twice a few minutes apart, treat it as a real problem.
• Compare http and https. If the secure version fails while the plain one works, look at your certificate or redirect setup.
• Read the header details when the code surprises you. The HTTP header checker shows the full response headers, which helps explain unexpected redirects or caching behavior.

If a site works in your browser but shows Unavailable here, the host may block automated requests, or the site may be down only for certain regions. Check the firewall or CDN settings and test again.

Limitations to Keep in Mind

This tool checks websites over HTTP and HTTPS, and nothing else. It does not show whether a Minecraft, Roblox, Fortnite or Xbox game server is online, and it does not report internet provider outages. For those, use the official status page of the game or provider.

It also does not ping ports, read Linux or Windows service states, or send alerts. Each run is a single snapshot at the moment you press the button, so it will not catch an outage that happened an hour ago. Because redirects are followed automatically, you see the final code rather than every hop in a redirect chain.

For deeper performance checks, such as modern protocol support, try the HTTP/2 and HTTP/3 checker. You can find related audit tools in the Website Audit and Performance category.

A fast server status check takes under a minute and tells you whether your pages answer, what code they return and how quickly they respond. Add your URLs to the box above, run the check, and fix any red or Unavailable rows first.
