I can confirm this. But it's not recent occurrence, it been like that for a very long time and especialy "my sales" which is often simply inaccessible for days (timeout error). AFAIK since introduction of new design, the site was never running smoothly, but things got much worse in few last months. "Lots of traffic" is a laughible excuse - the amount of traffic will only increase in the future, so if they want this site to function normally, they need to take measures immediately!
