Once again, I can't access any site that has BlogSpot in its URL. Did a live chat with Earthlink tech who tried all sorts of tricks to alter my computer's configuration AND rejected out of hand that it could possibly be an Earthlink system problem. An hour-and-a-half later, after following his instructions, I had to reinstall my wireless router. The tech seemed to think it was everybody's fault but Earthlink's.
I did get a couple of workarounds so that I can access my own site and a couple of others. But, for the first time in many years I have begun to consider the possibility of changing my ISP. My loyalty to Earthlink is about to wear out.
