I agree with you, connection speed matters a lot. But what I feel is even more problematic is the 504 Busy error that happened two consecutive days for now, at least for some hours. What is strange is that it was at the same moment approximatively.
As you mentioned 504 busy error first of all you should need to report that in Meta because it is quite mention in the error that you should go to report that in Meta. So i would like to say that. It is happen just because of traffic bitcointalk is improving that side because there are millions people who are coming online on bitcointalk therefore traffic goes more than the website goes down.
