The Internet is a dynamic monster constantly changing. Nothing is static. What is true today, will not be true tomorrow. Another truism is, there is alway something broken on the Internet.
This time of year, as the weather changes around the world, and the people are out on holidays and vacations, the Internet is just a nasty mess. Always has been, always will be. It may not effect you today, but there is a very good chance it will effect you tomorrow. Point being, the odds will catch up with you.
Then it will all change again.
A server, any server, would be hard pressed to cause a disconnect. A disconnect is an abnormal termination of a communication stream. If the server was causing it, it would, generally speaking, effect everyone at the same time.
