The fastest way to separate a service outage from a connection problem is to compare scope: open several unrelated websites, then try the affected service from another device or network. If many unrelated sites fail, investigate your Wi-Fi, Ethernet link, router, modem, or internet provider. If only one service fails, check that service’s official status page and test it elsewhere. Neither pattern is absolute—a browser, DNS resolver, device, or routing fault can make one site fail, while a provider incident can affect many destinations—but the comparison tells you what to check next.
Google Chrome Help gives the same first rule: “If the issue affects multiple websites, check your internet connection.” Use it as a clue, not as proof. Work through the checks below in order, changing one thing at a time so you can identify the cause instead of masking it.

Start with a two-minute scope test
Do not begin by changing DNS settings, reinstalling a browser, or resetting your router. First establish how broad the failure is.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Confirm the address. Check the spelling, top-level domain, and path. A typo or an old bookmark can look like an outage.
- Reload once. Use the browser’s reload control. If the page was partly loaded, note whether the error changes from a blank page to a specific message.
- Open several unrelated sites. Choose sites that use different services rather than several pages from the same company. Record whether each one loads, loads slowly, or times out.
- Try the affected service again in a private window or another browser. This separates a site problem from a stale cache, extension, blocked script, or expired login session.
- Compare another device on the same network. A phone and a laptop using the same Wi-Fi provide a useful device comparison.
- Compare another connection when available. A mobile-data hotspot, a workplace network, or a wired Ethernet connection can show whether the usual network path is involved. This is a diagnostic comparison, not a requirement to buy equipment.
Write down the time, the exact error text, and which combinations worked. A simple record prevents guesses such as “the internet is down” when only one browser or one domain is affected.

Use the failure pattern to choose the next branch
| What you observe | What it makes more plausible | Next check |
|---|---|---|
| One service fails, while unrelated sites work | Service incident, service-specific DNS or routing problem, browser issue, or account problem | Check the service’s official status page; retry in another browser, device, or network |
| Several unrelated sites fail on one device | Device Wi-Fi, Ethernet, DNS, security software, or browser configuration | Check the connection indicator, reconnect, try another browser, and compare another device |
| Several unrelated sites fail on every device on the same network | Router, modem, local network, or internet-provider problem | Inspect network equipment, test wired versus Wi-Fi if possible, restart equipment, then contact the ISP |
| The service works on mobile data but not on home Wi-Fi | Home-network DNS, routing, filtering, or provider path | Check the router and provider; preserve the working-versus-failing comparison for support |
| The service fails everywhere, including another network | Service outage, maintenance, or a problem with the account or service itself | Read the official incident information and wait for provider guidance; contact support if no incident is listed |
| A page opens but images, scripts, or login controls are missing | Partial service degradation, blocked requests, content-filtering, extension, or cache problem | Use a private window, disable extensions temporarily, and inspect browser requests if support asks |
These are probabilities, not verdicts. A local DNS failure can affect one popular domain while everything else works, and a regional service incident may leave users in other locations unaffected.
When only one website or service appears broken
Check the service’s own status information
Use the affected provider’s official status page, incident feed, or maintenance page. Look for the exact product or component, the affected regions, the incident start time, and whether the provider says it is investigating, mitigating, or resolved. A status page is evidence about that provider’s systems and infrastructure; it is not a health report for the entire internet.
Some providers publish a status dashboard, an independent notification channel, or a status feed. Those channels can differ in timing, so an empty dashboard does not prove that every customer can reach the service. Conversely, an incident entry does not tell you whether your local connection has a second, separate fault.
Test the same service outside the original setup
Open the service on another device using the same network. If it fails only on the original device, investigate that device’s browser, DNS cache, security software, clock, or account session. If it fails on every device on the same network, change the connection path: use mobile data or another trusted network if available. A result that changes when the network changes points toward the original path, although a regional outage can still affect more than one provider.
Separate account and browser symptoms from availability
A site that loads its home page but rejects a sign-in, shows an endless spinner, or omits embedded content may be available while a particular account, authentication system, or browser request is failing. Try a private window without saved cookies, then sign in only if the page loads normally. Check that the device date and time are correct because an incorrect clock can break secure connections. Do not repeatedly reset passwords or clear all browser data before recording the exact error; those actions can remove useful evidence.

When several unrelated websites fail
Verify Wi-Fi or Ethernet at the device
Check the operating system’s network indicator and confirm that the device is connected to the intended Wi-Fi network or Ethernet adapter. If Wi-Fi is connected but pages time out, disconnect and reconnect once. On a wired link, reseat the cable at both ends and check whether the port lights change. If a public network is involved, open a new browser tab and visit a plain, non-secure page to trigger its sign-in portal. Hotels, airports, libraries, and cafés can show a connected Wi-Fi icon while blocking internet traffic until you accept terms or enter a room number.
Move close to the access point only as a test. A weak radio signal, interference, or a crowded channel can cause intermittent timeouts even when the service itself is healthy. If another device works on the same Wi-Fi, focus on the failing device rather than immediately rebooting every network component.

Inspect the modem and router
Look at the power, internet, and link indicators and note any warning light or repeated restart cycle. Confirm that the network cable from the modem or fiber terminal to the router is firmly connected. If the equipment has separate power supplies, verify both are plugged in. A router’s local Wi-Fi can remain available even when its upstream internet connection has failed.
Restart equipment only when you can tolerate a brief interruption. Turn off or unplug the modem or fiber terminal and router, wait until their indicators go dark, then power the upstream device first. Allow it to finish synchronizing before powering the router. The exact light sequence varies by model; a persistent loss-of-signal or service indicator after startup is useful information for the ISP.
Check whether the problem follows the network
Test a second device on the same network. If both devices fail to reach unrelated sites, the common network path is more likely than two independent browser problems. If only one device fails, compare another browser, temporarily pause a recently installed VPN or security filter, and verify that the system has not been set to use an unreachable proxy. Restore any security setting after the test.

Compare connection paths without over-interpreting the result
A wired Ethernet test can remove Wi-Fi interference from the equation when the device and router have compatible ports. If Ethernet works while Wi-Fi fails, investigate wireless signal, access-point configuration, or radio interference. If both fail, the fault may be upstream of Wi-Fi. If mobile data works but the home connection does not, save that observation for the ISP; it narrows the issue to the home network or its provider path.
The reverse result also matters. If Wi-Fi works but one device’s mobile data does not, the mobile carrier path or that device’s cellular settings may be involved. A single successful request is not conclusive: repeat the test several times and note whether failures are intermittent, region-specific, or limited to a particular protocol such as image loading or video playback.
Read status pages with the right scope
An official status page can report incidents, scheduled maintenance, component health, regional impact, and updates from the provider’s operations team. Check the timestamp and affected location rather than relying only on a green overall banner. Some dashboards separate authentication, APIs, storage, search, payments, or media delivery; the component that matters to your task may be degraded while the headline service remains marked operational.
Cloudflare’s status documentation, for example, explains that a vendor status page can include location information, independent notifications, and status feeds. That illustrates how to use a provider dashboard, not a guarantee about any other service. Google’s status-dashboard explanations likewise apply to Google Search systems specifically. Always consult the service you are actually trying to use.
Third-party outage reports can be a clue that other people are seeing symptoms, but they cannot conclusively establish that a service is down for everyone. Reports may be delayed, concentrated in one country, or caused by a shared local provider. Treat them as supporting evidence and prioritize the affected service’s own notices plus your device-and-network comparisons.

| Symptom | Useful interpretation | Low-risk next action |
|---|---|---|
| DNS name cannot be found | Possible DNS resolver, typo, domain, or service-side DNS problem | Recheck the address, try another network, and compare a different browser |
| Connection timed out | No timely response; could be local connectivity, routing, congestion, filtering, or an unavailable server | Test unrelated sites and another connection before changing settings |
| Connection refused | A host or intermediate system actively rejected the connection, or the requested port is closed | Retry later and check the provider’s incident information |
| HTTP 4xx error | The server received a request but rejected it because of authorization, rate limits, location, or request details | Read the page’s explanation; avoid rapid repeated retries |
| HTTP 5xx error | The service or an upstream component reported a server-side failure | Check the official status page and retry after a short interval |
| Only images, scripts, or embedded tools fail | Partial outage, content delivery issue, extension, privacy filter, or blocked third-party request | Use a private window and inspect which requests fail |
| Very slow loading across many sites | Weak signal, congestion, packet loss, overloaded equipment, or provider impairment | Compare wired and Wi-Fi performance and note times of day |
Error codes are clues, not diagnoses. The same timeout can be produced by a local firewall or a remote server, so always combine the code with scope and comparison tests.

Optional advanced diagnostics for support cases
Use command-line tools when a provider or technical support agent asks for deeper evidence. They are not necessary for a first outage check, and their output can be confusing without context.
Inspect an HTTP response with curl
On macOS, Linux, Windows PowerShell, and many other systems, run:
curl -I https://example.comReplace the address with the affected service. The command requests headers and can show whether a server responds, which HTTP status it returns, and whether redirects occur. A browser may still behave differently because it sends cookies, JavaScript requests, authentication headers, and a different user agent.
Recommended Free Tools
To measure timing without printing the page, use:
curl -sS -o /dev/null -w "DNS: %{time_namelookup}snConnect: %{time_connect}snTLS: %{time_appconnect}snFirst byte: %{time_starttransfer}snTotal: %{time_total}snHTTP: %{http_code}n" https://example.comRun it more than once and record the date, network used, and destination. One slow result is not a benchmark. Do not paste private URLs, authorization headers, or response bodies into a public forum.
Trace the network path
On Windows, the command is:
tracert example.comOn macOS or Linux, use:
traceroute example.comWhere installed, mtr -rw example.com combines repeated probes with a route view. These tools can reveal where responses stop or latency increases, but many routers deliberately ignore probe packets. Asterisks at one hop do not prove that hop is broken, and a route can change between tests. Share the complete output with support only after removing internal hostnames, IP addresses, or other information your organization treats as confidential.

Capture a HAR file only when requested
A HAR file records browser network requests and responses while you reproduce a problem. In Chromium-based browsers, open Developer Tools, select the Network panel, enable Preserve log if support requests it, clear the existing entries, reproduce the failure, then use the panel’s option to save all requests as a HAR file with content. Labels can vary by browser version.
HAR files may contain cookies, authorization tokens, query parameters, account names, private paths, and response data. Open the file as text, remove or redact secrets, and follow the receiving provider’s secure-upload instructions. Never post an unsanitized HAR file in a public issue tracker or chat. If support does not need request-level detail, send the exact error text and timestamps instead.
Common mistakes that produce false conclusions
- Testing only one page. A homepage can be cached or served from a different component. Use several unrelated sites.
- Assuming a green status page means universal access. Dashboards have provider and often regional scope; a clean page does not prove reachability from your location.
- Blaming Wi-Fi because one site fails. If other sites work, investigate the service, browser, DNS, or account before resetting the router.
- Changing many settings at once. Record the original configuration and make one reversible change per test.
- Ignoring public-network sign-in. A connected icon may represent only a local link until the captive portal is completed.
- Reading one traceroute hop as proof. Probe filtering and asymmetric routes make isolated hop failures ambiguous.
- Sharing sensitive diagnostics. HAR files, command output, screenshots, and URLs can expose credentials or internal information.
- Repeating retries rapidly. Aggressive refreshes can trigger rate limits and make a temporary service problem harder to interpret.
When to contact the internet provider
Contact the ISP when several unrelated sites remain unavailable on multiple devices after you have checked the local connection and restarted network equipment appropriately. Provide the time the problem began, whether wired and Wi-Fi tests differ, which devices were tested, the modem or router indicator state, and whether mobile data or another network worked. Ask whether there is a known outage or maintenance event for your area.
If only one service fails while other sites work, contact that service’s support after checking its official status information and reproducing the issue on another connection. Include the exact error, affected region, device and browser versions, and timestamps. State what worked as well as what failed; a support agent can use that contrast to distinguish an account issue from a network path problem.
A compact decision checklist
- Confirm the URL and reload once.
- Open several unrelated websites.
- If several fail, check Wi-Fi or Ethernet, public-network sign-in, and modem/router indicators.
- Compare a second device on the same network.
- If one service fails, read its official status page and try another browser or private window.
- Compare another network when available, recording the result and time.
- Restart network equipment only when appropriate, allowing the modem or fiber terminal to synchronize before the router.
- Escalate persistent multi-site failures to the ISP; use HAR, curl, or traceroute/MTR only for advanced support cases and sanitize anything you share.
The reliable answer comes from combining scope, device comparisons, connection-path tests, and provider evidence. One failed page or one green dashboard is not enough; a consistent pattern across independent tests is what tells you where to look.
