Especially yesterday, there did seem to be some widespread internet disruptions. My friend in Arizona was trying to book tickets for me and was having problems, then I tried and I was having problems. And a couple of times when we were talking my land line (through my comcast digital connection) broke off. We are also having fiber optic stuff installed around my area, but it seemed to be national.
But I have never been able to figure out combinations of whatever and my sometimes problems of getting logged out often here are. Sometimes I am logged in for hours, sometimes for minutes... I prefer to stay not logged in all the time on sites so it isn't so annoying.
