Is Server Up?

是您还是网站或服务器已关闭？

Quick way to test if a website or a server is down or there's a problem with your connection.

Very easy to setup and with very handy features:

- auto-refresh

- when running in background, there's a notification with the latest results

- low data usage (only the header of webpages is transferred)

- extremely low footprint: around 400KB!

- no cookies, no tracking, no logs, nothing whatsoever is sent to an outside server

Troubleshoot:

- depending on your router configuration, ping on machines on internal network (10.x or 192.168.x) could not pass through.

- ping requests could be filtered by the server firewall
