I am having continual slow responses when using Googlemail. With 30MB+ fibre broadband and other sites opening very quickly it seems to me it the Google infrastructure itself. I have just sent an email and now face the message "working.." - for 5 mins now.

I have not found a way of notifying Google directly so I will try this method. I am based in the UK.
