And begins to doubt this server is down, or the native provider wants to break a contract with you. In this situation, help is one of the sites that test the availability of sites.

0. Is Twitter Down? - the easiest and most currently used theoretically pinger. Checks only one part of the incident, but still a popular site.

1. Down for everyone or just me? - as simple web-tool to ping. No milliseconds heap of servers (at least visible) and paid services. Simply enter the website address and get a result.

2. Uptime Party - a feature-rich service from the creators of «Down for everyone ...». Apart from a quick test, it allows you to subscribe to a notification by electromail fall on the site. You can check the free 1 server every hour. Paying a penny, you can increase the number of servers up to five or ten, and the upgrade to 30 or 15 minutes.

3. Watchmouse - one of the pages of paid pingers. Plus in a number of randomly selected checks the server and display the response time. For the money (not small), you can sign up for periodic inspections, but after Uptime Party is meaningless.

4. just ping - 26 servers located around the world at your service. Similar to Watchmouse, but more servers and less graphics.

5. traceroute.org - a great number of local traceroute. All show the response time from different servers of a certain region.
