PINGING COSP.JP @ 220.127.116.11
* Ping failure does not necessary mean that the website is not working. Ping may be disabled on host by the sysadmin.
A website status check is now in progress to see whether the cosp.jp site is down or not. Please be patient. If the results do not appear within 30 seconds, first check the entered domain name and then try to reload or refresh this page.
What to do, if the site is up for everyone else
First of all check your browser's local settings, or you could also try to use a proxy server (most ISPs have official, but there are free ones as well).
If you are trying to connect to a website through your browser and the website is not opening, you receive a connection timed out, server not found or website down error message, please make sure that in your browser's File menu Work Offline is unchecked.
You could try to reload the site directly from the Internet. This can be done by pressing CTRL + F5 keys at the same time. Sometimes a firewall or other security software is disabling you to visit a web page, and there is also a possibility that your ISP has some kind of network problems.
Disable security software: failed page loads can be caused by anti-virus and firewall software as well. Disable them to make sure they don't block pages.
There are other browsers: try browsing with opera, firefox or chrome. You could also check the page from another computer and network.
Restart computer: remember that sometimes the most obvious solution is the best solution. Simply restart your computer and see what happens.
Try alternative website check: try to test website availability from another independent location like websitedown.info online status checker tool.
