🛰️ Quick tool to see if you can reach common IPs, resolve DNS, and load popular sites — Test country blockages and VPNs.
Perform a fast series of checks from your current network to help you understand whether common web stuff is reachable and how fast (ping, DNS, popular news and social websites).
- Ping some well‑known anycast IPs like 1.1.1.1 and 8.8.8.8
- Resolve DNS A records for some major domains like google.com and bing.com
- Fetch your public IP and rough geo-location (city / region / country) from ipinfo.io
- The returned location may be inaccurate, e.g. VPN in UAE may show England
- Try to reach a set of popular websites in several countries, reporting:
- Country
- HTTP status or timeout / error
- Latency in ms

PING_HOSTS– list of IPs to ICMP ping once each.DNS_HOSTS– hostnames to A‑record resolve.SITES– array of{ host, country }entries (ISO 3166‑1 alpha‑2 exceptXXused here for "Other").CHECK_CONCURRENCY– max concurrent website fetch.CHECK_TIMEOUT_MS– per‑site timeout (ms) for theHEADrequest.
Just append / delete objects in the SITES array.
Currently HEAD is used in httpProbe (utils.ts) to reduce data transfer. Change to GET if you need deeper reachability checks (increases bandwidth / time).
| Issue | Hint |
|---|---|
ping: command not found |
Ensure ping is available (minimal containers may lack it). |
| All pings fail | Possible local firewall / ICMP blocked. |
| DNS failures | Check local resolver / network connectivity. |
| All HTTP probes timeout | Likely egress filtering or captive portal. |
| Public IP fetch fails | Temporary issue reaching ipinfo.io or blocked; retry or substitute another service. |
