Enter up to 100 URLs (Each URL must be on separate line)
You type a web address into your browser, hit enter, and stare at a blank white screen. The little loading wheel spins in circles for 30 seconds. Then you see a generic error message telling you the site took too long to respond.
Your first thought is usually annoyance. You wonder if your home Wi-Fi cut out, or if the website itself crashed for everyone on the planet. That is why we built the free Server Status Checker on Marketer Milk. This tool dials the target domain from an external computer outside your home network. It pings the host and gives you the exact HTTP response code in seconds. You find out immediately whether you are facing a private connection problem or a total website blackout.
Website downtime burns real money. If you run an online store, every minute your checkout page stays broken means lost orders that never come back. Shoppers give up fast. If a page refuses to load after 3 seconds, they click back to Google and spend their cash with your rival. Search engines care about page availability too. Google sends web crawlers to your site every single day to look for new pages and updates.
When those automated crawlers hit repeated server errors, Google pulls back. The search engine slows down its crawl rate to protect your server from overloading. If your pages stay down for several days in a row, Google drops your URLs from search results to protect searchers from broken links. Uptime also protects your marketing budget. If you run paid search ads or social media campaigns, sending clicks to a dead server burns cash on empty visits. Checking server status lets you pause campaigns the moment an outage begins.
Your home web browser travels through multiple layers to open a web page. First, your laptop talks to your local Wi-Fi router. Your router talks to your internet service provider (ISP). Your ISP looks up the domain name through a DNS directory, routes your request through underwater cables, and finally knocks on the hosting company's door. A failure at any single point along that physical chain will cause your browser to show a timeout screen.
The Server Status Checker tests the website from a remote cloud server. It skips your home hardware, your local cable lines, and your neighborhood internet routing hubs. Our tool queries the domain directly from a clean data center connection. It sends an HTTP request to the target server and waits for a response packet. If our testing node gets an immediate answer, the website is working fine across the broader internet. If our testing node gets an error code or an empty response, the website's host server is offline.
Testing any domain takes only a few seconds. First, copy the full website address you want to inspect from your browser address bar.
Paste the address directly into the input box on Marketer Milk. If you want to test several websites at once, paste each web address on its own line. Click the check button to begin the test. Our testing system pings each URL in your list and prints the live status code next to each domain name. You will see green checkmarks for healthy servers and red alerts for offline hosts.
Servers speak in numerical response codes whenever a browser knocks on their door. These numbers tell you what the host computer is doing behind the scenes. Here is what the standard response codes mean when you run a check.
A 200 response means the server is online, healthy, and delivering the requested page content. This is the standard status you want to see for your primary content pages. The server received the visitor's request, found the correct files in its storage, and transmitted them back without errors.
A 300-level code means the page moved to a different web address. A 301 response means the move is permanent. The server tells the browser to update its bookmarks and pass search value to the new URL. A 302 response means the move is temporary. Both codes mean the server is running properly, but the browser must take an extra hop to load the final destination page.
codeText
HTTP/1.1 301 Moved Permanently
Location: https://example.com/new-page
A 403 code means the host computer is running, but it refuses to let your request inside. Websites use 403 protections on administrative login portals and private staging directories. Firewalls also throw 403 errors when they detect automated scrapers, bot traffic, or IP addresses from specific geographical regions. The server is active, but your connection got blocked at the front gate.
A 404 code means the host server is running fine, but it cannot locate the specific URL path you requested. This happens when someone deletes an old blog post or mistypes a word in the address bar. Your server hardware is completely healthy in this scenario. You simply need to restore the missing file or set up a 301 redirect pointing visitors to a working page.
codeText
HTTP/1.1 404 Not Found
Content-Type: text/html; charset=UTF-8
A 500 code means the server crashed while trying to build the web page. This usually points to broken software code, faulty PHP scripts, or database connection failures. The physical hardware is awake and taking calls, but the software running on that machine choked on a script error. You will need to inspect your application error logs to find which line of code broke the page.
A 502 error occurs in multi-server web setups. Modern websites often use a proxy server or content delivery network sitting in front of their main application host. When the front-end proxy knocks on the back-end host and receives an invalid response, it sends back a 502 code. This indicates your origin database or application server died while the front-end gatekeeper stayed online.
A 503 response means the host server cannot handle the volume of requests hitting it right now. This happens during sudden traffic spikes, distributed denial-of-service attacks, or scheduled server maintenance windows. The machine is alive, but its memory and processing chips are pinned at 100% capacity. The server drops incoming requests to keep its operating system from locking up entirely.
codeText
HTTP/1.1 503 Service Unavailable
Retry-After: 300
A 504 code means the front-end proxy server waited for the back-end application server, but the clock ran out before an answer arrived. Slow database queries and heavy file operations cause 504 timeouts. The origin machine took too long to chew through the database records, so the edge network gave up and closed the connection.
You might find that your website opens fine on our checking tool, but your personal phone still shows an error. Local technical conflicts cause this split. Here are the primary reasons a website looks dead on your screen while remaining live for the rest of the world.
Computers save domain lookups in local storage to speed up daily browsing. When a website migrates to a new hosting provider or changes its IP address, your laptop might keep dialing the old, abandoned IP number. You can fix this by clearing your computer's DNS cache. On a Windows PC, open the command prompt and run this command:
codeBash
ipconfig /flushdns
On an Apple Mac, open the terminal application and paste this command:
codeBash
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
This wipes your computer's temporary memory bank. Your machine will ask public internet directories for the fresh IP coordinates on your next click.
Open a private or incognito browsing window to test this. Private windows bypass saved cache files and pull everything fresh from the hosting server. If the site opens inside an incognito tab, clear your browser history and cookies to fix your primary window.
Corporate security suites and home antivirus software monitor outgoing web traffic. Aggressive security filters sometimes flag safe websites as malicious targets, cutting the data line before the page reaches your screen. Virtual private networks (VPNs) can cause identical lockouts. Many cloud hosts block entire blocks of shared VPN IP addresses to defend against spam bots and scrapers. Disconnect from your VPN software and refresh the target URL to see if your connection returns.
Checking URLs one at a time works when you run a single small personal blog. Agencies and marketing consultants face a tougher job. I manage dozens of client accounts across Marketer Milk, and inspecting 40 domains manually every morning eats up half the workday. Our Server Status Checker supports batch testing right inside the main input area. You can paste 20, 50, or 100 client links into the box in one go. The tool checks each server concurrently and outputs a master status list.
You can spot broken landing pages, dead client portals, and bad redirects in a few seconds. This bulk test is helpful right before you turn on paid ad campaigns. Running a quick bulk check ensures that every destination URL in your ad groups resolves to an active 200 OK status before you spend marketing dollars on traffic.
Confirming that a website is down is step one. Finding out why it crashed requires extra diagnostic tools.
Our status code checker traces the full hop-by-hop path of a redirect chain. Sometimes a URL redirects through 4 different web addresses before reaching its final destination. Each jump slows down page delivery and drains search engine crawl budgets. The status code tool maps every individual jump and flags redirect loops that choke web crawlers.
Web headers carry technical instructions between the server and the browser. They display your caching instructions, cookie settings, content types, and server software versions. Inspecting headers shows you whether your content delivery network is serving pages from cache or pulling directly from your origin host.

When an outage lingers for hours, you often need to contact the company hosting the physical machine. Our hosting checker inspects the public IP address and identifies the data center running the domain. You can check whether the hosting company is suffering a widespread regional power failure or network outage across their server farm.
Yes. The tool runs completely free inside your browser on Marketer Milk. You can run single checks or bulk domain audits without creating an account or providing an email address.
Check your core marketing pages at least once a week. If you run high-volume e-commerce campaigns or manage enterprise clients, set up automated monitoring software that pings your host every 5 minutes. Automated pings wake you up with a text alert the moment your server drops offline.
Start by logging into your hosting dashboard to see if your hardware ran out of memory or disk storage. Restart your web server software, such as Nginx or Apache, to clear stuck system processes. If a software restart fails, contact your hosting support desk immediately so their technicians can check the physical host machine. Save your error log files so your developers can inspect the code crashes after service returns.
