how to tell if one website is down or my whole internet connection on iphone

A page that will not load can reflect one destination, DNS, TLS, an IP-version path or the wider connection, so a useful test compares layers instead of labeling every failure an internet outage.

짧은 답변

WiFi Aid's Check a Website examines a specific destination beside the broader connection evidence. Compare its DNS result, TCP connection, TLS negotiation, TTFB and HTTP response with independent internet, IPv4 and IPv6 observations. Direct IP adds only a bounded numeric-IP TCP observation; it does not inspect the server, capture packets or prove the site is globally down. The app reports the most likely interpretation with confidence; confirm important outages through the website operator or another independent source.

Check the current App Store listing before buying; WiFi Aid is a paid download with no free trial. After purchase, compare a real failing destination with the broader connection evidence before drawing a conclusion.

선택 전에 확인할 점

  • Check one destination beside independent wider-connection observations
  • Distinguish DNS, TCP, TLS, TTFB and HTTP stages
  • Compare IPv4 and IPv6 path evidence when the results differ
  • Use numeric-IP TCP only as a bounded supporting observation
  • Avoid claiming that one iPhone check proves a global website outage

실용적인 선택 절차

  1. Run the broader connection check to establish a comparison.
  2. Use Check a Website for the destination that is failing.
  3. Compare DNS, TCP, TLS, TTFB and HTTP results with the broader evidence.
  4. Check whether IPv4 and IPv6 observations point to different paths.
  5. Confirm a consequential site outage with the operator or another independent source.

자주 묻는 질문

Can one failed website test prove that the site is down for everyone?

No. It helps compare that destination with the broader connection, but a global outage needs confirmation from the operator or another independent source.

What layers can explain why only one site fails?

The evidence can distinguish DNS, TCP, TLS, TTFB, HTTP and IPv4 or IPv6 observations.

Does the app inspect the website's server?

No. It makes bounded connection observations from the iPhone and does not claim server access or packet capture.
