Weird problem, server loses connection every hour?
I have no idea what is causing this weird problem. Ever since I had to restore my site on a new harddrive, every hour or so my server appears as if it goes offline or loses connection for a minute, then everything comes back and there is no evidence of any problems. The load is not high, there is plenty of RAM, there are no errors about anything being down or having to be restarted, but every hour suddenly my sites go offline and display the "Page cannot be displayed" error but everything returns to normal a minute later. Is it perhaps ServerMatrix network lag?
Depending on what system and what webserver you use. If it is Apache I suspect it could be caused by max connection limit. I have experienced this myself with Apache on Win2k3 and the condition matches your description perfectly.
When you get that "page cannot be displayed" error, try and ping your server to see if it is Apache's fault for not serving you or it is the server that is not responding to any incoming connection.
