I have a garage door opener server that works for 4 or so days and then stops (Firefox times out and says that it took too long). This is not installed at my house, so I thought it was the internet connection. I can ping the address without any loss. The odd thing is that I was not able to access the site a few tries, then it worked but would not reload (or when the meta refresh happened, it would time out) and then I could not access it anymore.
