Up
The target host returned a successful response during the latest probe.
Quick answer: this tool helps answer whether a site is down for everyone or just you, using a live domain probe, response timing, and practical next checks.
The target host returned a successful response during the latest probe.
The probe timed out or returned an unavailable result for the host.
Measured round-trip time in milliseconds for the latest status request.
A site can be up globally but still inaccessible locally due to ISP routing, DNS cache issues, enterprise firewalls, or regional network incidents.
Anonymous aggregate counts only. We store domain popularity and status-check timestamps, never IP addresses, session IDs, or user identifiers.

Start with high-demand checks below. Each route uses one canonical format so results are easier to share, cite, and revisit.
Monitor high-impact developer infrastructure domains for release and incident triage.
Use these guides to diagnose outages and resolver issues faster.
Check whether a website is up, down, or invalid using a live availability probe. The check runs directly from your browser and does not use a Plain Tools proxy.
Enter any domain and this tool normalizes it to a canonical status route. Checks run live and return current reachability plus response timing.
A site can be up globally but still fail locally due to resolver, ISP routing, or firewall conditions.
Need more than uptime? Jump into DNS, IP, and latency checks in the same network toolkit.
It runs a live probe and reports whether a host responds as up, down, or invalid.
Yes. Each domain has a canonical route such as /status/reddit.com for repeat checks and sharing.
No. This tool checks network availability only and does not process or upload document files.
A status result shows whether the target domain responded during the latest probe. Use this as a practical signal for first-line triage, then follow up with DNS and latency checks to isolate routing or resolver issues.
