We have been having major problems with our internet for the past couple of months. We are running online applications via a Metro Ethernet circuit and our web browsing is routed through a T1 connection. Well, the problem is that the majority of the time, neither web browsing, nor our online applications work really at all. When I try to access a web page, it will take forever and it will say that it is loading, then 20 minutes later it will give a page not responding error. Sometimes things seem to work without a problem, but most of the time (like 90% of the time), things don't work at all. Someone told me that it is an internal problem, possibly with one of our switches? How would one go about analysing his/her switches to see where the problem might be or what would be the first steps in figuring this out?
