Site uptime

Hi guys.Our company has created a web site that is hosted at
The problem is that for many hours every day that website is not accessible from us and when it is happening we cannot access our emails.
How can I check if the problem is from our side? (since most of these times when we check with it seems that the rest of the word can access the site)
Is there a 3rd party service that can check site uptime and probably pinpoint the exact location of the problem in the traceroute?
Thank you very much!:slight_smile: has worked well for me… it won’t tell you the exact location but it can monitor your site every 5 mins and tell you if it’s up for down.
