I seem to be having some connectivity problems today. My email monitor frequently reports that it couldn't access my mailbox - I'm still getting the mail - it just can't always get an answer when it asks.
I also find that visiting many sites initially gives me a backwards (anticlockwise) connection indicator, suggesting it's not going to work, before it sorts itself out, and the indicator starts going clockwise.
This is not very easy to explain, as I don't know what that thing is called. The circle that shows that you're connecting...or not. Backwards circling usually means not.
