I'm browsing on slightly off peak hours and I'm not seeing any slowdown or degradation in the server response times. I would suspect there is a higher level of traffic today given that the site was down yesterday. That would be my first guess as to what may be causing some of the peak hour slowdown. People really need there HTF fix.
I don't want to talk out of turn here so please shoot me down if I am, but would extra cash flow help in mitigating some of these problems? Is this a good time to reevaluate payment/donation options?
