You click a link, the page spins, and then you get an error. Is the website down for everyone, or is your own internet broken? Guessing wrong wastes time — you either reboot routers for no reason or sit waiting for a site that will not come back for hours.
The good news is that you can answer this question in under two minutes with a simple sequence of checks. No technical background is needed, and most of the tools are free websites and settings already on your phone and computer.
This guide gives you that exact sequence, explains the error messages you will see, and shows you how to tell the difference between a website outage, a DNS problem, and a fault on your own home network.
Quick Answer
Try opening two or three other well-known websites. If they load, your internet works and the original site is likely down — confirm it on a status checker. If nothing loads on any device, your internet connection or home router is the problem, so restart the router and check your provider’s outage page.
Start With the 30-Second Triage
Do not start by unplugging everything. First narrow down where the failure sits: the website, your device, your home network, or your provider.
Step 1: Try Other Websites
Open three sites you do not normally visit at the same time, such as a news site, a search engine, and a video site. If all of them load normally, your connection is alive and the problem is almost certainly the original website.
If some load and some do not, you may have a DNS issue or a partial provider outage. If none load, move on to checking other devices before you conclude anything.
Step 2: Try a Second Device
Pick up your phone and try the same failing website, first on Wi-Fi and then with Wi-Fi turned off so it uses mobile data.
- If the site fails on your computer but works on your phone using mobile data, the site is up and your home internet or computer is at fault.
- If the site fails on both Wi-Fi and mobile data, the website itself is very likely down.
- If every site fails on Wi-Fi but works on mobile data, your home broadband or router has failed.
- If every site fails on every device and connection, check whether there is a wider regional or national outage.
This single test, switching between Wi-Fi and mobile data, is the fastest way to separate a website problem from a home internet problem.
Use a Website Status Checker
Once your quick tests suggest the website is at fault, confirm it with an independent checker instead of relying on your own browser.
How Downdetector and Similar Tools Work
Sites like Downdetector for real-time outage reports from other users collect problem reports and show a live graph. A sharp spike in reports in the last 15 to 60 minutes is strong evidence of a real outage. A flat line with only a handful of reports suggests the problem is on your side.
You can also search for a phrase like “is it down right now” checkers where you paste the website address and the service tries to load it from its own servers in another country. If that service can load it but you cannot, the site is up globally and the fault is local or regional.
Check the Company’s Official Status Page
Large services publish their own status dashboards listing each product as operational, degraded, or down. Banks, cloud providers, gaming networks, and social platforms all maintain them, and they are more precise than crowd reports.
Also check the company’s social media account, often the first place an outage is acknowledged. Our guide to fixing DNS errors when websites will not load covers what to do if a status checker says a site is up but it still will not open for you.
Understanding Browser Error Messages
Your browser is already telling you a lot about where the problem is. You just need to read the error correctly.
DNS and Name Errors
Messages such as “DNS_PROBE_FINISHED_NXDOMAIN”, “server IP address could not be found”, or “This site can’t be reached” with a DNS note mean your device could not translate the website name into an address. The site may be fine, but your DNS server has failed or has a bad record.
Try switching your DNS to 1.1.1.1 or 8.8.8.8 in your router or device settings and reload the page. If it works immediately, you have found the culprit.
Timeout, 403, 404, and 500 Errors
A connection timeout usually means the site’s server is overloaded, down, or blocking your connection. A 404 error means the site is definitely up — its server answered you — but that specific page no longer exists or the address is mistyped.
A 500 or 502 error also means the site’s server responded but has an internal fault. You cannot fix 500-series errors from home; you can only wait. A 403 error means the server understood you but refuses access, which can happen if a VPN or a regional block is involved.
Check Your Own Internet Properly
If other websites also fail, now it is time to check your own connection methodically rather than randomly rebooting things.
Look at the Router Lights and Restart Correctly
A red or flashing amber internet light on the router or on the fibre optical terminal usually means the line itself has lost connection. A solid white or green light with no access suggests a device or Wi-Fi problem instead.
Restart in this order:
- Turn off the router and, if you have one, the separate modem or fibre terminal.
- Wait a full 30 seconds — this clears the session properly with your provider.
- Turn the modem or fibre terminal on first and wait until its lights are stable.
- Turn the router on and give it two to three minutes to reconnect and restore Wi-Fi.
- Test again with a device wired by Ethernet if possible, to remove Wi-Fi from the equation.
If a wired device works but Wi-Fi devices do not, your internet is fine and your Wi-Fi needs attention — a channel change, a firmware update, or repositioning the router.
Run a Ping and Speed Test
On Windows, open Command Prompt and type ping 8.8.8.8. On a Mac, open Terminal and type the same command. Replies in 10 to 50ms mean your internet path is alive even if websites fail, which points back to DNS. “Request timed out” means the connection itself is broken.
Then run a test through Speedtest by Ookla to verify your current download and upload speeds. A result near zero or a test that cannot even start confirms a line fault you should report to your provider with the time the outage began.
When It Is Your Provider, Not You
Search your provider’s name plus “outage” or check its official service status page using mobile data. Major providers publish affected postcodes or regions and estimated repair times during larger incidents.
Weather damage, a cut cable from roadworks, and overnight maintenance between midnight and 6am are the most common causes. If your provider confirms an area outage, there is nothing to fix at home.
If neighbours on the same provider share the problem, that confirms a provider-level fault.
Common Mistakes to Avoid
The most common mistake is clearing your browser cache and reinstalling apps before doing the basic second-device and mobile-data tests. Those steps rarely fix an outage and they waste the first ten minutes when simple tests would have told you the truth.
Another mistake is trusting a single status website without checking the time. An outage graph from three hours ago does not explain a problem happening now, so always look at the last 30 minutes of reports.
Do not factory-reset your router during an outage. You will lose your provider settings and Wi-Fi configuration, turning a temporary external fault into a longer self-inflicted one. A simple power restart is safe; a reset is a last resort on provider advice only.
Conclusion
Telling a website outage apart from broken home internet is a process of elimination that takes two minutes: try other sites, try a second device on mobile data, confirm with a status checker, and read the browser error carefully.
If everything fails everywhere, restart the modem and router in the right order and check your provider’s status. If only one site fails everywhere, the problem is theirs, not yours — save your time, check back later, and avoid changing settings that were never broken.
Frequently Asked Questions
How can I tell if a website is down for everyone?
Check a crowd-report site such as Downdetector for a sharp spike in recent reports and try a down-checker that loads the site from another location. If both show problems and the site also fails on mobile data, it is down for everyone.
Why does one website not load while everything else works?
Usually that site has its own outage, a DNS problem, or it is blocking your IP range or VPN. Try mobile data, try changing your DNS to 1.1.1.1, and check its official status page before changing anything else.
What does it mean if Wi-Fi works on my phone but not my laptop?
Your internet and router are fine and the fault is on the laptop — often a stuck Wi-Fi driver, a wrong saved network setting, or security software. Restart the laptop, forget and rejoin the Wi-Fi network, and update its wireless driver.
Should I call my provider as soon as the internet stops working?
Wait ten minutes and do one proper router restart first, because many glitches clear themselves. If a wired test still fails and lights show no connection, call them and note the time and the light status to speed up the call.
Can a VPN make it look like a website is down?
Yes. Some sites block known VPN addresses or the VPN server itself can fail. Disconnect the VPN and reload the page. If it loads instantly without the VPN, the website was never down.
