I've been experiencing the problems since about 6pm on Sunday evening and it's not gotten any better, hasn't changed appreciably depending where I've tried in the Central US either.
In the past 36 hours or so it's been occurring, I've tried connecting in areas around Omaha, Lincoln, Kansas City, Fort Worth, Las Vegas, and Denver. Las Vegas was normal, all the other locations have been horrible with pages usually taking several attempts to load if they load at all.
