You're staring at a blank white screen. Or maybe it’s that annoying "spinning wheel of death" that just won't quit. You’ve refreshed the page five times. You’ve toggled your Wi-Fi on and off. You even considered restarting your router, which—let's be honest—is a massive pain because it’s tucked behind the couch. But before you crawl under the furniture, you have to ask the golden question: is a site down, or is it just you?
It’s a frustratingly common scenario. One minute you’re scrolling through Reddit or trying to check out on Amazon, and the next, the digital world just... stops. Honestly, the internet feels incredibly fragile when this happens. We rely on these platforms for basically everything, so when a major player like Google, Slack, or Instagram hiccups, it feels like a mini-apocalypse.
But here is the thing: "down" doesn't always mean the same thing. Sometimes the server is literally on fire (metaphorically, usually). Other times, a DNS setting somewhere in Virginia got tweaked by a tired engineer, and now half the world can't find their way to a specific URL. Understanding the nuance of why a site fails can save you a lot of troubleshooting time.

How to Check if a Site is Down Right Now
Stop guessing. There are actually tools for this that don't involve texting your friend, "Hey, is Netflix working for you?"
The most reliable way to verify the status of a platform is to use a third-party aggregator. Sites like DownDetector or Is It Down Right Now? are the gold standard here. They don't just check if the server is responding; they crowdsource reports from thousands of users in real-time. If you see a massive spike in a red graph, you know it’s not your ISP. It’s them.
Cloudflare also maintains a very transparent status page. Since Cloudflare powers a massive chunk of the internet's infrastructure, if they are having an "incident," you can bet a dozen of your favorite apps are going to be wonky. It's also worth checking the official social media accounts of the service in question. Twitter (X) is usually the first place companies post when things go south, though "checking Twitter" is getting harder if Twitter itself is the one having the outage.

The "Just Me" vs. "Everyone" Test
Sometimes a site is technically "up" but won't load for you. This is the "Partial Outage" nightmare. Maybe the login server is fried, but the homepage loads fine. To get a clear answer, try these three things:
- Try Incognito Mode: This disables your extensions and uses a fresh set of cookies. If the site loads here, your browser cache is the culprit.
- Switch to Mobile Data: If a site loads on your phone’s 5G but not on your home Wi-Fi, your ISP might be having a DNS issue or your router is blocking the site.
- Check a "Ping" Service: Tools like Site24x7 or Pingdom can ping a site from different geographic locations like London, Singapore, or New York. If it’s up in London but down in New York, you’re looking at a regional CDN failure.
Why Big Websites Randomly Break
It seems impossible that a company worth billions could just... break. But they do. All the time. Facebook famously vanished from the internet for hours in 2021. Not just the app—their entire internal network was gone. Their badges didn't even work to let employees into the building.
The culprit? BGP (Border Gateway Protocol). Think of BGP as the "map" of the internet. If a company accidentally deletes their map, the rest of the internet literally doesn't know how to find their servers. It’s like a city disappearing off a GPS while you’re driving toward it.
DNS Issues: The Phonebook Problem
Most of the time when people ask "is a site down," the real issue is DNS (Domain Name System). When you type google.com, your computer asks a DNS server for an IP address. If that server is slow or has wrong information, you get an error. This is why many tech-savvy people switch their DNS settings to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) instead of using the default one provided by Comcast or AT&T. It’s often faster and much more reliable.

CDN Failures
Content Delivery Networks (CDNs) like Fastly or Akamai are the backbone of the modern web. They store copies of websites on servers all over the world so they load faster. But if Fastly goes down, sites like CNN, The New York Times, and Twitch go down with it. These are "cascading failures." One small piece of the puzzle breaks, and the whole picture falls apart.
Don't Let Your Browser Lie to You
Your browser is a hoarder. It saves bits of websites—images, scripts, CSS—so it doesn't have to download them every single time. This is called caching. It’s great for speed, but it’s terrible for troubleshooting. If a site was down ten minutes ago and it’s back up now, your browser might still be trying to show you the "down" version it saved.
You’ve got to force a "Hard Refresh." On Windows, it’s usually Ctrl + F5. On Mac, it’s Cmd + Shift + R. This tells the browser, "Forget what you know. Go get the newest version of this page right now." Honestly, this fixes about 40% of the issues people have when they think a site is down.
What to Do When the Internet is Actually Broken
If you’ve confirmed the site is down and it’s not just your Wi-Fi, there isn't much you can do but wait. However, "waiting" doesn't mean you have to be unproductive.
- Check for a "Lite" Version: Some sites have a mobile-only or basic HTML version that might still be running while the main site is struggling.
- Use Wayback Machine: If you just need to read an article or see information on a page that is currently dead, the Internet Archive’s Wayback Machine might have a snapshot from yesterday.
- Check the Status Page: Most professional SaaS companies (like Slack, Zoom, or Trello) have a specific
status.companyname.compage. These are hosted on separate infrastructure, so they stay up even when the main service is down. They will give you an ETA for the fix.
It’s easy to get annoyed, but remember that the web is a massive, interconnected web of cables under the ocean and satellites in space. It’s a miracle it works as well as it does.
Actionable Troubleshooting Steps
Next time you hit a wall, follow this exact sequence to stop wasting time:
- Verify with DownDetector. If the spike is huge, walk away. It’s a server-side issue.
- Perform a Hard Refresh (
Ctrl + F5). Don't skip this. - Try a different device. If it works on your phone, the issue is your computer or your browser settings.
- Clear your DNS cache. On Windows, open Command Prompt and type
ipconfig /flushdns. It’s a "magic fix" for many "site not found" errors. - Check your VPN. Sometimes a VPN server in a specific city is having issues. Try disconnecting it or switching to a different country.
Stop fighting with your hardware. If a site is truly down, the engineers at that company are likely panicking and working at 100mph to fix it. Give them twenty minutes. Usually, by the time you've made a cup of coffee, the "map" will be fixed, the BGP routes will be updated, and the digital world will be back in its place.
Next Steps for You
If you are consistently seeing "Site Can't Be Reached" errors on many different websites, the problem isn't the sites—it's your DNS. Consider changing your router's DNS settings to a public provider like Cloudflare (1.1.1.1) or Google (8.8.8.8). This is a one-time change that significantly reduces the frequency of "false positive" outages and often makes your general browsing feel snappier. Check your router’s manual or a quick online guide for your specific model to make the switch.
